[This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2.1 of the License, or (at your option) any later version. This library is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License for more details. You should have received a copy of the GNU Lesser General Public License along with this library; if not, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Also add information on how to contact you by electronic and paper mail. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the library, if necessary.

It is 'very' similar to the libmp3lame API. See simplefrontend/simplefrontend.c for a very simple application using the API. Steps to encode PCM to MP2 -------------------------- 1. Grab a set of default options by calling: twolame_options *encodeOptions; encodeOptions = twolame_init(); 2. Adjust those options to suit your requirements. See twolame.h for a full list of options. eg. twolame_set_out_samplerate(encodeOptions, 32000); twolame_set_bitrate(encodeOptions, 160); 3. Initialise twolame library with these options by calling: twolame_init_params(encodeOptions); NOTE: The return value should be checked to see if the options were valid. Currently only ever returns 0 4. Encode PCM audio to MP2 by calling: int twolame_encode_buffer( twolame_options *glopts, // the set of options you're using const short int leftpcm[], // the left and right audio channels const short int rightpcm[], int num_samples, // the number of samples in each channel unsigned char *mp2buffer, // a pointer to a buffer for the MP2 audio data // NB User must allocate space! int mp2buffer_size); // The size of the mp2buffer that the user allocated int *mp2fill_size); This function returns the number of bytes written into mp2buffer by the library MPEG. One frame of MPEG audio will be returned for every 1152 samples of PCM audio. Multiple calls can be made to this function. It is the users responsibility to: - allocate the mp2buffer - read the pcmaudio from somewhere with new samples always staring from the beginning of the buffer - write the mp2buffer contents to somewhere (it is overwritten with each call) 5. Flush the encoder by calling: int twolame_encode_flush( twolame_options *glopts, unsigned char *mp2buffer, int mp2buffer_size); When encoding is finished, unless there was exactly a multiple of 1152 samples/channel sent to the encoder, there will be some remaining audio that is not encoded. This function encodes this last bit of audio by padding out with zeros until there is 1152 samples per channel in the PCM audio buffers and then encoding this. This function returns the number of bytes written into mp2buffer by the library MPEG. 6. The user must "de-initialise" the encoder at the end by calling: void twolame_close(twolame_options **glopts); This function must be called to free all the memory and structures associated with this set of encoding parameters.

This is the interface for encoding PCM audio to MPEG Audio Layer 2.

It is very similar to the libmp3lame API.

See simplefrontend/simplefrontend.c for a very simple application using the API.

Steps to encode PCM to MP2

  1. Grab a set of default options by calling: 

    twolame_options *encodeOptions;
encodeOptions = twolame_init();

  2. Adjust those options to suit your requirements. See twolame.h for a full list of options. eg. 

    twolame_set_out_samplerate(encodeOptions, 32000);
twolame_set_bitrate(encodeOptions, 160);

  3. Initialise twolame library with these options by calling: 

    twolame_init_params(encodeOptions);
    NOTE: The return value should be checked to see if the options were valid.
Currently only ever returns 0

  4. Encode PCM audio to MP2 by calling: 

    int twolame_encode_buffer(
 twolame_options *glopts,   // the set of options you're using
 const short int leftpcm[], // the left and right audio channels
 const short int rightpcm[],
 int num_samples,           // the number of samples in each channel
 unsigned char *mp2buffer,  // a pointer to a buffer for the MP2 audio data
                            // NB User must allocate space!
 int mp2buffer_size);       // The size of the mp2buffer that the user allocated
 int *mp2fill_size);
    This function returns the number of bytes written into mp2buffer by the library MPEG.
One frame of MPEG audio will be returned for every 1152 samples of PCM audio.
Multiple calls can be made to this function.
It is the users responsibility to:

    • allocate the mp2buffer

    • read the pcmaudio from somewhere with new samples always staring from the beginning of the buffer

    • write the mp2buffer contents to somewhere (it is overwritten with each call)

  5. Flush the encoder by calling: 

    int twolame_encode_flush(
    twolame_options *glopts,
    unsigned char *mp2buffer,
    int mp2buffer_size);
    When encoding is finished, unless there was exactly a multiple of 1152 samples/channel
sent to the encoder, there will be some remaining audio that is not encoded. This function
encodes this last bit of audio by padding out with zeros until there is 1152 samples per channel
in the PCM audio buffers and then encoding this.
    This function returns the number of bytes written into mp2buffer by the library MPEG.

  6. The user must "de-initialise" the encoder at the end by calling: 

    void twolame_close(twolame_options **glopts);
    This function must be called to free all the memory and structures
associated with this set of encoding parameters.
POST: glopts = NULL

DOT_TRANSPARENT = YES # Set the DOT_MULTI_TARGETS tag to YES allow dot to generate multiple output # files in one run (i.e. multiple -o and -T options on the command line).

Introduction

In MPEG audio encoding, a psychoacoustic model (PAM) is used to determine which are the sonically important parts of the waveform that is being encoded. The PAM looks for loud sounds which may mask soft sounds, noise which may affect the level of sounds nearby, sounds which are too soft for us to hear and should be ignored and so on. The information from the PAM is used to determine which parts of the spectrum should get more bits and thus be encoded at greater quality - and which parts are inaudible/unimportant and should thus get fewer bits.

In MPEG Audio LayerII encoding, 1152 sound samples are read in - this constitutes a frame. For each frame the PAM outputs just 32 values (The values are the Signal to Masking Ratio [SMR] in that subband). This is important! There are only 32 values to determine how to alloctate bits for 1152 samples - this is a pretty coarse technique.

The different PAMs listed below use different techniques to decide on these 32 values. Some models are better than others - meaning that the 32 values chosen are pretty good at spreading the bits where they should go. Even with a really bad PAM (e.g. Model -1) you can still get satisfactory results a lot of the time. All of these models have strengths and weaknesses. The model you end up using will be the one that produces the best sound for your ears, for your audio.

Psychoacoustic Model -1

This PAM doesn’t actually look at the samples being encoded to decide upon the output values. There is simply a set of 32 default values which are used, regardless of input.

Pros: Faaaast. Low complexity. Surprisingly good. "Surprising" in that the other PAMs go to the effort of calculating FFTs and subbands and masking, and this one does absolutely nothing. Zip. Nada. Diddly Squat. This model might be the best example of why it is hard to make a good model - if having no computations sounds OK, how do you improve on it?

Cons: Absolutely no attempt to consider any of the masking effects that would help the audio sound better.

Psychoacoustic Model 0

This PAM looks at the sizes of the scalefactors for the audio and combines it with the Absolute Threshold of Hearing (ATH) to make the 32 SMR values.

Pros: Faaast. Low complexity.

Cons: This model has absolutely no mathematical basis and does not use any perceptual model of hearing. It simply juggles some of the numbers of the input sound to determine the values. Feel free to hack the daylights out of this PAM - add multipliers, constants, log-tables anything. Tweak it until you begin to like the sound.

Psychoacoustic Model 1 and 2

These PAMs are from the ISO standard. Just because they are the standard, doesn’t mean that they are any good. Look at LAME which basically threw out the MP3 standard psycho models and made their own (GPSYCHO).

Pros: A reference for future PAMs

Cons: Terrible ISO code, buggy tables, poor documentation.

Psychoacoustic Model 3

A re-implementation of psychoacoustic model 1. ISO11172 was used as the guide for re-writing this PAM from the ground up.

Pros: No more obscure tables of values from the ISO code. Hopefully a good base to work upon for tweaking PAMs

Cons: At the moment, doesn’t really sound any better than PAM1

Psychoacoustic Model 4

A cleaned up version of PAM2.

Pros: Faster than PAM2. No more obscure tables of values from the ISO standard. Hopefully a good base to work from for improving the PAMs

Cons: Still has the same "warbling"/"Davros" problems as PAM2.

Future psychoacoustic models

There’s a heap that could be done. Unfortunately, I’ve got a set of tin ears, crappy speakers and a noisy computer room. If you’ve got the capability to do proper PAM testing then please feel free to do so. Otherwise, I’ll just keep plodding along with new ideas as they arise, such as:

  • Temporal masking (there’s no pre-echo or anything in TwoLAME)

  • Left Right Masking

  • A PAM that’s fully tuneable from the command line?

  • Graphical output of SMR values etc. Would allow better debugging of PAMs

  • Re-sampling routines

  • Low/High pass filtering

INTRODUCTION

TwoLAME is an optimized MPEG Audio Layer 2 (MP2) encoder. It is based heavily on:

  • tooLAME by Michael Cheng

  • the ISO dist10 code

  • improvement to algorithms as part of the LAME project (lame.sf.net)

  • other contributors (see AUTHORS)

TwoLAME should be able to be used as a drop-in replacement for LAME (a MPEG Layer 3 encoder). The frontend takes very similar command line options to LAME, and the backend library has a very similar API to LAME.

For the latest version of TwoLAME, visit the project homepage: http://www.twolame.org/

MPEG Audio Layer 2 (MP2)

(taken from Wikipedia article on MP2)

MP2 (sometimes incorrectly named Musicam) is a short form of MPEG Audio Layer II, and it is also used as a file extension for files containing audio data of this type. While it has largely been superseded by MP3 for PC and Internet applications, it remains a dominant standard for audio broadcasting as part of the DAB digital radio and DVB digital television standards. It is also used internally within the radio industry, for example in NPR’s PRSS Content Depot programming distribution system.

INSTALLATION

Standard automake process:

./configure
make
make install

  • use Exact-width integer types (eg uint16_t)

  • Add libresample support to libtwolame (twolame_set_in_samplerate etc.)

  • parameter checking in twolame.c using assert

  • Create a new twolame.spec (be sure to include twolame.pc)

  • quite a lot of duplicated code between twolame_encode_buffer_interleaved and twolame_encode_buffer

  • sort out changing parameter for twolame_set_VBR_q from FLOAT to int (like LAME)

  • better use of verbosity settings

  • full options sanity checking/verification in twolame_init_params

  • don’t allow twolame_set_* after twolame_init_params() has been called

  • Fix broken DAB support

  • with this VBR mode, we know the bits aren’t going to run out, so we can just assign them "greedily".

  • VBR_a_bit_allocation() is yet to be written :)

  • Add a layer 2 decoder ? mpglib ?

  • use 32-bit floats internally where possible

SYNOPSIS

twolame [options] <infile> [outfile]

DESCRIPTION

TwoLAME is an optimised MPEG Audio Layer 2 (MP2) encoder based on tooLAME by Mike Cheng, which in turn is based upon the ISO dist10 code and portions of LAME. Encoding is performed by the libtwolame library backend.

OPTIONS

Input File

twolame uses libsndfile for reading the input sound file, so the input file can be in any format supported by libsndfile. To read raw PCM audio from STDIN, then use - as the input filename.

Output File

If no output filename is specified, then suffix of the input filename is automatically changed to .mp2. To write the encoded audio to STDOUT then use - as the output filename.

Input Options

-r, --raw-input

Specifies that input is raw signed PCM audio. If audio is stereo, than audio samples are interleaved between the two channels.

-x, --byte-swap

Force byte-swapping of the input. Endian detection is performed automatically by libsndfile, so this option shouldn’t normally be needed.

-s, --samplerate <int>

If inputting raw PCM sound, you must specify the sample rate of the audio in Hz. Valid sample rates: 16000, 22050, 24000, 32000, 44100, 48000Hz. Default sample rate is 44100Hz.

--samplesize <int>

Specifies the sample size (in bits) of the raw PCM audio. Valid sample sizes: 8, 16, 24, 32. Default sample size is 16-bit.

-N, --channels <int>

If inputting raw PCM sound, you must specify the number of channels in the input audio. Default number of channels is 2.

-g, --swap-channels

Swap the Left and Right channels of a stereo input file.

--scale <float>

Scale the input audio prior to encoding. All of the input audio is multiplied by specified value. Value between 0 and 1 will reduce the audio gain, and a value above 1 will increase the gain of the audio.

--scale-l <float>

Same as --scale, but only affects the left channel.

--scale-r <float>

Same as --scale, but only affects the right channel.

Output Options

-m, --mode <char>

Choose the mode of the resulting audio. Default is auto.

  • "a" auto - choose mode automatically based on the input

  • "s" stereo

  • "d" dual channel

  • "j" joint stereo

  • "m" mono

-a, --downmix

If the input file is stereo then, downmix the left and right input channels into a single mono channel.

-b, --bitrate <int>

Sets the total bitrate (in kbps) for the output file. The default bitrate depends on the number of input channels and samplerate. 

------------------------------
Sample Rate   Mono    Stereo
------------------------------
48000         96      192
44100         96      192
32000         80      160
24000         48      96
22050         48      96
16000         32      64
------------------------------
-P, --psyc-mode <int>

Choose the psycho-acoustic model to use (-1 to 4). Model number -1 is turns off psycho-acoustic modelling and uses fixed default values instead. Please see the file psycho for a full description of each of the models available. Default model is 3.

-v, --vbr

Enable VBR mode. See vbr documentation file for details. Default VBR level is 5.0.

-V, --vbr-level <float>

Enable VBR mode and set quality level. The higher the number the better the quality. Maximum range is -50 to 50 but useful range is -10 to 10. See vbr documentation file for details.

-l, --ath <float>

Set the ATH level. Default level is 0.0.

-q, --quick <int>

Enable quick mode. Only re-calculate psycho-acoustic model every specified number of frames.

-S, --single-frame

Enables single frame mode: only a single frame of MPEG audio is output and then the program terminates.

Miscellaneous Options

-c, --copyright

Turn on Copyright flag in output bitstream.

-o, --non-original

Turn off Original flag in output bitstream.

--original

Turn on Original flag in output bitstream.

-p, --protect

Enable CRC error protection in output bitstream. An extra 16-bit checksum is added to frames.

-d, --padding

Turn on padding in output bitstream.

-R, --reserve <int>

Reserve specified number of bits in the each from of the output bitstream.

-e, --deemphasis <char>

Set the de-emphasis type (n/c/5). Default is none.

-E, --energy

Turn on energy level extensions.

Verbosity Options

-t, --talkativity <int>

Set the amount of information to be displayed on stderr (0 to 10). Default is 2.

--quiet

Don’t send any messages to stderr, unless there is an error. (Same as --talkativity=0)

--brief

Only display a minimal number of messages while encoding. This setting is quieter than the default talkativity setting. (Same as --talkativity=1)

--verbose

Display an increased number of messages on stderr. This setting is useful to diagnose problems. (Same as --talkativity=4)

Return Codes

If encoding completes successfully, then twolame will return 0. However if encoding is not successful, then it will return one of the following codes.

  • 1 (No encoding performed)

  • 2 (Error opening input file)

  • 4 (Error opening output file)

  • 6 (Error allocating memory)

  • 8 (Error in chosen encoding parameters)

  • 10 (Error reading input audio)

  • 12 (Error occured while encoding)

  • 14 (Error writing output audio)

EXAMPLES

This will encode sound.wav to sound.mp2 using the default constant bitrate of 192 kbps and using the default psycho-acoustic model (model 3):

twolame sound.wav

Constant bitrate of 160kbps and joint stereo encoding, saved to file sound_160.mp2:

twolame -b 160 -m j sound.aiff sound_160.mp2

Encode sound.wav to newfile.mp2 using psycho-acoustic model 2 and encoding with variable bitrate:

twolame -P 2 -v sound.wav newfile.mp2

Same as example above, except that the negative value of the "-V" argument means that the lower bitrates will be favoured over the higher ones:

twolame -P 2 -V -5 sound.wav newfile.mp2

Resample audio file using sox and pipe straight through twolame:

sox sound_11025.aiff -t raw -r 16000 | twolame -r -s 16000 - - > out.mp2

Introduction

VBR mode works by selecting a different bitrate for each frame. Frames which are harder to encode will be allocated more bits i.e. a higher bitrate.

LayerII VBR is a complete hack - the ISO standard actually says that decoders are not required to support it. As a hack, its implementation is a pain to try and understand. If you’re mega-keen to get full range VBR working, either (a) send me money (b) grab the ISO standard and a C compiler and email me.

Usage

twolame -v [level] inputfile outputfile.

A level of 5 works very well for me.

The level value can is a measurement of quality - the higher the level the higher the average bitrate of the resultant file. See TECH STUFF for a better explanation of what the value does.

The confusing part of my implementation of LayerII VBR is that it’s different from MP3 VBR.

  • The range of bitrates used is controlled by the input sampling frequency. (See below "Bitrate ranges")

  • The tendency to use higher bitrates is governed by the <level>.

E.g. Say you have a 44.1kHz Stereo file. In VBR mode, the bitrate can range from 192 to 384 kbps.

Using "-v -5" will force the encoder to favour the lower bitrate.

Using "-v 5" will force the encoder to favour the upper bitrate.

The value can actually be any int. -27, 233, 47. The larger the number, the greater the bitrate bias.

Bitrate Ranges

When making a VBR stream, the bitrate is only allowed to vary within set limits

48kHz
Stereo: 112-384kbps  Mono: 56-192kbps
44.1kHz & 32kHz
Stereo: 192-384kbps  Mono: 96-192kbps
24kHz, 22.05kHz & 16kHz
Stereo/Mono: 8-160kbps

Why doesn’t the VBR mode work the same as MP3VBR? The Short Answer

Why can’t the bitrate vary from 32kbps to 384kbps for every file?

According to the standard (ISO/IEC 11172-3:1993) Section 2.4.2.3

"In order to provide the smallest possible delay and complexity, the
 decoder is not required to support a continuously variable bitrate when
 in layer I or II.  Layer III supports variable bitrate by switching the
 bitrate index."
and
"For Layer II, not all combinations of total bitrate and mode are allowed."

Hence, most LayerII coders would not have been written with VBR in mind, and LayerII VBR is a hack. It works for limited cases. Getting it to work to the same extent as MP3-style VBR will be a major hack.

(If you really want better bitrate ranges, read "The Long Answer" and submit your mega-patch.)

Why doesn’t the VBR mode work the same as MP3VBR? The Long Answer

Why can’t the bitrate vary from 32kbps to 384kbps for every file?

Reason 1: The standard limits the range

As quoted above from the standard for 48/44.1/32kHz:

"For Layer II, not all combinations of total bitrate and mode are allowed. See
 the following table."
Bitrate         Allowed Modes
(kbps)
32              mono only
48              mono only
56              mono only
64              all modes
80              mono only
96              all modes
112             all modes
128             all modes
160             all modes
192             all modes
224             stereo only
256             stereo only
320             stereo only
384             stereo only

So based upon this table alone, you could have VBR stereo encoding which varies smoothly from 96 to 384kbps. Or you could have have VBR mono encoding which varies from 32 to 192kbps. But since the top and bottom bitrates don’t apply to all modes, it would be impossible to have a stereo file encoded from 32 to 384 kbps.

But this isn’t what is really limiting the allowable bitrate range - the bit allocation tables are the major hurdle.

Reason 2: The bit allocation tables don’t allow it

From the standard, Section 2.4.3.3.1 "Bit allocation decoding"

"For different combinations of bitrate and sampling frequency, different bit
 allocation tables exist.

These bit allocation tables are pre-determined tables (in Annex B of the standard) which indicate

  • how many bits to read for the initial data (2,3 or 4)

  • these bits are then used as an index back into the table to find the number of quantize levels for the samples in this subband

But the table used (and hence the number of bits and the calculated index) are different for different combinations of bitrate and sampling frequency.

I will use TableB.2a as an example.

Table B.2a Applies for the following combinations.

Sampling Freq           Bitrates in (kbps/channel) [emphasis: this is a PER CHANNEL bitrate]
48                      56, 64, 80, 96, 112, 128, 160, 192
44.1                    56, 64, 80
32                      56, 64, 80

If we have a STEREO 48kHz input file, and we use this table, then the bitrates we could calculate from this would be 112, 128, 160, 192, 224, 256, 320 and 384 kbps.

This table contains no information on how to encode stuff at bitrates less than 112kbps (for a stereo file). You would have to load allocation table B.2c to encode stereo at 64kbps and 128kbps.

Since it would be a MAJOR piece of hacking to get the different tables shifted in and out during the encoding process, once an allocation table is loaded IT IS NOT CHANGED.

Hence, the best table is picked at the start of the encoding process, and the encoder is stuck with it for the rest of the encode.

For twolame-02j, I have picked the table it loads for different sampling frequencies in order to optimize the range of bitrates possible.

48 kHz - Table B.2a
         Stereo Bitrate Range: 112 - 384
         Mono Bitrate Range : 56 - 192
44.1/32 kHz - Table B.2b
        Stereo Bitrate Range: 192 - 384
        Mono Bitrate Range: 96 - 192
24/22.05/16 kHz - LSF Table (Standard ISO/IEC 13818.3:1995 Annex B, Table B.1)
        There is only 1 table for the Lower Sampling Frequencies
        All modes (mono and stereo) are allowable at all bitrates
        So at the Lower Sampling Frequencies you *can* have a completely variable
        bitrate over the entire range.

Tech Stuff

The VBR mode is mainly centered around the main_bit_allocation() and a_bit_allocation() routines in encode.c.

The limited range of VBR is due to my particular implementation which restricts ranges to within one alloc table (see tables B.2a, B.2b, B.2c and B.2d in ISO 11172). The VBR range for 32/44.1khz lies within B.2b, and the 48khz VBR lies within table B.2a.

I’m not sure whether it is worth extending these ranges down to lower bitrates. The work required to switch alloc tables during the encoding is major.

In the case of silence, it might be worth doing a quick check for very low signals and writing a pre-calculated blank 32kpbs frame. [probably also a lot of work].

How CBR works

  • Use the psycho model to determine the MNRs for each subband [MNR = the ratio of "masking" to "noise"] (From an encoding perspective, a bigger MNR in a subband means that it sounds better since the noise is more masked))

  • calculate the available data bits (adb) for this bitrate.

  • Based upon the MNR (Masking:Noise Ratio) values, allocate bits to each subband

  • Keep increasing the bits to whichever subband currently has the min MNR value until we have no bits left.

  • This mode does not guarentee that all the subbands are without noise ie there may still be subbands with MNR less than 0.0 (noisy!)

How VBR works

  • pretend we have lots of bits to spare, and work out the bits which would raise the MNR in each subband to the level given by the argument on the command line "-v [int]"

  • Pick the bitrate which has more bits than the required_bits we just calculated

  • calculate a_bit_allocation()

  • VBR "guarantees" that all subbands have MNR > VBRLEVEL or that we have reached the maximum bitrate.

FUTURE

  • with this VBR mode, we know the bits aren’t going to run out, so we can just assign them "greedily".

  • VBR_a_bit_allocation() is yet to be written :)

The PAM looks for loud sounds which may mask soft sounds, noise which may affect the level of sounds nearby, sounds which are too soft for us to hear and should be ignored and so on. The information from the PAM is used to determine which parts of the spectrum should get more bits and thus be encoded at greater quality - and which parts are inaudible/unimportant and should thus get fewer bits. In MPEG Audio LayerII encoding, 1152 sound samples are read in - this constitutes a 'frame'. For each frame the PAM outputs just *32* values (The values are the Signal to Masking Ratio [SMR] in that subband). This is important! There are only 32 values to determine how to alloctate bits for 1152 samples - this is a pretty coarse technique. The different PAMs listed below use different techniques to decide on these 32 values. Some models are better than others - meaning that the 32 values chosen are pretty good at spreading the bits where they should go. Even with a really bad PAM (e.g. Model -1) you can still get satisfactory results a lot of the time. All of these models have strengths and weaknesses. The model 'you' end up using will be the one that produces the best sound for your ears, for your audio. Psychoacoustic Model -1 ----------------------- This PAM doesn't actually look at the samples being encoded to decide upon the output values. There is simply a set of 32 default values which are used, regardless of input. *Pros*: Faaaast. Low complexity. Surprisingly good. "Surprising" in that the other PAMs go to the effort of calculating FFTs and subbands and masking, and this one does absolutely *nothing*. Zip. Nada. Diddly Squat. This model might be the best example of why it is hard to make a good model - if having no computations sounds OK, how do you improve on it? *Cons*: Absolutely no attempt to consider any of the masking effects that would help the audio sound better. Psychoacoustic Model 0 ---------------------- This PAM looks at the sizes of the 'scalefactors' for the audio and combines it with the Absolute Threshold of Hearing (ATH) to make the 32 SMR values. *Pros*: Faaast. Low complexity. *Cons*: This model has absolutely no mathematical basis and does not use any perceptual model of hearing. It simply juggles some of the numbers of the input sound to determine the values. Feel free to hack the daylights out of this PAM - add multipliers, constants, log-tables *anything*. Tweak it until you begin to like the sound. Psychoacoustic Model 1 and 2 ---------------------------- These PAMs are from the ISO standard. Just because they are the standard, doesn't mean that they are any good. Look at LAME which basically threw out the MP3 standard psycho models and made their own (GPSYCHO). *Pros*: A reference for future PAMs *Cons*: Terrible ISO code, buggy tables, poor documentation. Psychoacoustic Model 3 ---------------------- A re-implementation of psychoacoustic model 1. ISO11172 was used as the guide for re-writing this PAM from the ground up. *Pros*: No more obscure tables of values from the ISO code. Hopefully a good base to work upon for tweaking PAMs *Cons*: At the moment, doesn't really sound any better than PAM1 Psychoacoustic Model 4 ---------------------- A cleaned up version of PAM2. *Pros*: Faster than PAM2. No more obscure tables of values from the ISO standard. Hopefully a good base to work from for improving the PAMs *Cons*: Still has the same "warbling"/"Davros" problems as PAM2. Future psychoacoustic models ---------------------------- There's a heap that could be done. Unfortunately, I've got a set of tin ears, crappy speakers and a noisy computer room. If you've got the capability to do proper PAM testing then please feel free to do so. Otherwise, I'll just keep plodding along with new ideas as they arise, such as: - Temporal masking (there's no pre-echo or anything in TwoLAME) - Left Right Masking - A PAM that's fully tuneable from the command line? - Graphical output of SMR values etc. Would allow better debugging of PAMs - Re-sampling routines - Low/High pass filtering twolame-0.3.13/doc/twolame.10000644000076500000240000002234311516345602012473 00000000000000'\" t .\" Title: twolame .\" Author: Nicholas J Humfrey .\" Generator: DocBook XSL Stylesheets v1.74.3 .\" Date: 01/21/2011 .\" Manual: \ \& .\" Source: \ \& .\" Language: English .\" .TH "TWOLAME" "1" "01/21/2011" "\ \&" "\ \&" .\" ----------------------------------------------------------------- .\" * set default formatting .\" ----------------------------------------------------------------- .\" disable hyphenation .nh .\" disable justification (adjust text to left margin only) .ad l .\" ----------------------------------------------------------------- .\" * MAIN CONTENT STARTS HERE * .\" ----------------------------------------------------------------- .SH "NAME" twolame \- an optimised MPEG Audio Layer 2 (MP2) encoder .SH "SYNOPSIS" .sp \fItwolame\fR [options] [outfile] .SH "DESCRIPTION" .sp TwoLAME is an optimised MPEG Audio Layer 2 (MP2) encoder based on tooLAME by Mike Cheng, which in turn is based upon the ISO dist10 code and portions of LAME\&.

Encoding is performed by the libtwolame library backend. OPTIONS ------- Input File ~~~~~~~~~~ twolame uses libsndfile for reading the input sound file, so the input file can be in any format supported by libsndfile. To read raw PCM audio from STDIN, then use - as the input filename. Output File ~~~~~~~~~~~ If no output filename is specified, then suffix of the input filename is automatically changed to .mp2. To write the encoded audio to STDOUT then use - as the output filename. Input Options ~~~~~~~~~~~~~ -r, --raw-input:: Specifies that input is raw signed PCM audio. If audio is stereo, than audio samples are interleaved between the two channels. -x, --byte-swap:: Force byte-swapping of the input. Endian detection is performed automatically by libsndfile, so this option shouldn't normally be needed. -s, --samplerate :: If inputting raw PCM sound, you must specify the sample rate of the audio in Hz. Valid sample rates: 16000, 22050, 24000, 32000, 44100, 48000Hz. Default sample rate is 44100Hz. --samplesize :: Specifies the sample size (in bits) of the raw PCM audio. Valid sample sizes: 8, 16, 24, 32. Default sample size is 16-bit. -N, --channels :: If inputting raw PCM sound, you must specify the number of channels in the input audio. Default number of channels is 2. -g, --swap-channels:: Swap the Left and Right channels of a stereo input file. --scale :: Scale the input audio prior to encoding. All of the input audio is multiplied by specified value. Value between 0 and 1 will reduce the audio gain, and a value above 1 will increase the gain of the audio. --scale-l :: Same as --scale, but only affects the left channel. --scale-r :: Same as --scale, but only affects the right channel. Output Options ~~~~~~~~~~~~~~ -m, --mode :: Choose the mode of the resulting audio. Default is auto. - "a" auto - choose mode automatically based on the input - "s" stereo - "d" dual channel - "j" joint stereo - "m" mono -a, --downmix:: If the input file is stereo then, downmix the left and right input channels into a single mono channel. -b, --bitrate :: Sets the total bitrate (in kbps) for the output file. The default bitrate depends on the number of input channels and samplerate. ------------------------------ Sample Rate Mono Stereo ------------------------------ 48000 96 192 44100 96 192 32000 80 160 24000 48 96 22050 48 96 16000 32 64 ------------------------------ -P, --psyc-mode :: Choose the psycho-acoustic model to use (-1 to 4). Model number -1 is turns off psycho-acoustic modelling and uses fixed default values instead. Please see the file 'psycho' for a full description of each of the models available. Default model is 3. -v, --vbr:: Enable VBR mode. See 'vbr' documentation file for details. Default VBR level is 5.0. -V, --vbr-level :: Enable VBR mode and set quality level. The higher the number the better the quality. Maximum range is -50 to 50 but useful range is -10 to 10. See 'vbr' documentation file for details. -l, --ath :: Set the ATH level. Default level is 0.0. -q, --quick :: Enable quick mode. Only re-calculate psycho-acoustic model every specified number of frames. -S, --single-frame:: Enables single frame mode: only a single frame of MPEG audio is output and then the program terminates. Miscellaneous Options ~~~~~~~~~~~~~~~~~~~~~ -c, --copyright:: Turn on Copyright flag in output bitstream. -o, --non-original:: Turn off Original flag in output bitstream. --original:: Turn on Original flag in output bitstream. -p, --protect:: Enable CRC error protection in output bitstream. An extra 16-bit checksum is added to frames. -d, --padding:: Turn on padding in output bitstream. -R, --reserve :: Reserve specified number of bits in the each from of the output bitstream. -e, --deemphasis :: Set the de-emphasis type (n/c/5). Default is none. -E, --energy:: Turn on energy level extensions. Verbosity Options ~~~~~~~~~~~~~~~~~ -t, --talkativity :: Set the amount of information to be displayed on stderr (0 to 10). Default is 2. --quiet:: Don't send any messages to stderr, unless there is an error. (Same as --talkativity=0) --brief:: Only display a minimal number of messages while encoding. This setting is quieter than the default talkativity setting. (Same as --talkativity=1) --verbose:: Display an increased number of messages on stderr. This setting is useful to diagnose problems. (Same as --talkativity=4) Return Codes ------------ If encoding completes successfully, then twolame will return 0. However if encoding is not successful, then it will return one of the following codes. - 1 (No encoding performed) - 2 (Error opening input file) - 4 (Error opening output file) - 6 (Error allocating memory) - 8 (Error in chosen encoding parameters) - 10 (Error reading input audio) - 12 (Error occured while encoding) - 14 (Error writing output audio) EXAMPLES -------- This will encode sound.wav to sound.mp2 using the default constant bitrate of 192 kbps and using the default psycho-acoustic model (model 3): twolame sound.wav Constant bitrate of 160kbps and joint stereo encoding, saved to file sound_160.mp2: twolame -b 160 -m j sound.aiff sound_160.mp2 Encode sound.wav to newfile.mp2 using psycho-acoustic model 2 and encoding with variable bitrate: twolame -P 2 -v sound.wav newfile.mp2 Same as example above, except that the negative value of the "-V" argument means that the lower bitrates will be favoured over the higher ones: twolame -P 2 -V -5 sound.wav newfile.mp2 Resample audio file using sox and pipe straight through twolame: sox sound_11025.aiff -t raw -r 16000 | twolame -r -s 16000 - - > out.mp2 AUTHORS ------- The twolame frontend was (re)written by Nicholas J Humfrey.

Frames which are harder to encode will be allocated more bits i.e. a higher bitrate. LayerII VBR is a complete hack - the ISO standard actually says that decoders are not required to support it. As a hack, its implementation is a pain to try and understand. If you're mega-keen to get full range VBR working, either (a) send me money (b) grab the ISO standard and a C compiler and email me. Usage ----- twolame -v [level] inputfile outputfile. A level of 5 works very well for me. The level value can is a measurement of quality - the higher the level the higher the average bitrate of the resultant file. See TECH STUFF for a better explanation of what the value does. The confusing part of my implementation of LayerII VBR is that it's different from MP3 VBR. - The range of bitrates used is controlled by the input sampling frequency. (See below "Bitrate ranges") - The tendency to use higher bitrates is governed by the . E.g. Say you have a 44.1kHz Stereo file. In VBR mode, the bitrate can range from 192 to 384 kbps. Using "-v -5" will force the encoder to favour the lower bitrate. Using "-v 5" will force the encoder to favour the upper bitrate. The value can actually be *any* int. -27, 233, 47. The larger the number, the greater the bitrate bias. Bitrate Ranges -------------- When making a VBR stream, the bitrate is only allowed to vary within set limits 48kHz Stereo: 112-384kbps Mono: 56-192kbps 44.1kHz & 32kHz Stereo: 192-384kbps Mono: 96-192kbps 24kHz, 22.05kHz & 16kHz Stereo/Mono: 8-160kbps Why doesn't the VBR mode work the same as MP3VBR? The Short Answer ------------------------------------------------------------------ *Why can't the bitrate vary from 32kbps to 384kbps for every file?* According to the standard (ISO/IEC 11172-3:1993) Section 2.4.2.3 "In order to provide the smallest possible delay and complexity, the decoder is not required to support a continuously variable bitrate when in layer I or II. Layer III supports variable bitrate by switching the bitrate index." and "For Layer II, not all combinations of total bitrate and mode are allowed." Hence, most LayerII coders would not have been written with VBR in mind, and LayerII VBR is a hack. It works for limited cases. Getting it to work to the same extent as MP3-style VBR will be a major hack. (If you *really* want better bitrate ranges, read "The Long Answer" and submit your mega-patch.) Why doesn't the VBR mode work the same as MP3VBR? The Long Answer ----------------------------------------------------------------- *Why can't the bitrate vary from 32kbps to 384kbps for every file?* Reason 1: The standard limits the range ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ As quoted above from the standard for 48/44.1/32kHz: "For Layer II, not all combinations of total bitrate and mode are allowed. See the following table." Bitrate Allowed Modes (kbps) 32 mono only 48 mono only 56 mono only 64 all modes 80 mono only 96 all modes 112 all modes 128 all modes 160 all modes 192 all modes 224 stereo only 256 stereo only 320 stereo only 384 stereo only So based upon this table alone, you *could* have VBR stereo encoding which varies smoothly from 96 to 384kbps. Or you could have have VBR mono encoding which varies from 32 to 192kbps. But since the top and bottom bitrates don't apply to all modes, it would be impossible to have a stereo file encoded from 32 to 384 kbps. But this isn't what is really limiting the allowable bitrate range - the bit allocation tables are the major hurdle. Reason 2: The bit allocation tables don't allow it ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ From the standard, Section 2.4.3.3.1 "Bit allocation decoding" "For different combinations of bitrate and sampling frequency, different bit allocation tables exist. These bit allocation tables are pre-determined tables (in Annex B of the standard) which indicate - how many bits to read for the initial data (2,3 or 4) - these bits are then used as an index back into the table to find the number of quantize levels for the samples in this subband But the table used (and hence the number of bits and the calculated index) are different for different combinations of bitrate and sampling frequency. I will use TableB.2a as an example. Table B.2a Applies for the following combinations. Sampling Freq Bitrates in (kbps/channel) [emphasis: this is a PER CHANNEL bitrate] 48 56, 64, 80, 96, 112, 128, 160, 192 44.1 56, 64, 80 32 56, 64, 80 If we have a STEREO 48kHz input file, and we use this table, then the bitrates we could calculate from this would be 112, 128, 160, 192, 224, 256, 320 and 384 kbps. This table contains no information on how to encode stuff at bitrates less than 112kbps (for a stereo file). You would have to load allocation table B.2c to encode stereo at 64kbps and 128kbps. Since it would be a MAJOR piece of hacking to get the different tables shifted in and out during the encoding process, once an allocation table is loaded *IT IS NOT CHANGED*. Hence, the best table is picked at the start of the encoding process, and the encoder is stuck with it for the rest of the encode. For twolame-02j, I have picked the table it loads for different sampling frequencies in order to optimize the range of bitrates possible. 48 kHz - Table B.2a Stereo Bitrate Range: 112 - 384 Mono Bitrate Range : 56 - 192 44.1/32 kHz - Table B.2b Stereo Bitrate Range: 192 - 384 Mono Bitrate Range: 96 - 192 24/22.05/16 kHz - LSF Table (Standard ISO/IEC 13818.3:1995 Annex B, Table B.1) There is only 1 table for the Lower Sampling Frequencies All modes (mono and stereo) are allowable at all bitrates So at the Lower Sampling Frequencies you *can* have a completely variable bitrate over the entire range. Tech Stuff ---------- The VBR mode is mainly centered around the main_bit_allocation() and a_bit_allocation() routines in encode.c. The limited range of VBR is due to my particular implementation which restricts ranges to within one alloc table (see tables B.2a, B.2b, B.2c and B.2d in ISO 11172). The VBR range for 32/44.1khz lies within B.2b, and the 48khz VBR lies within table B.2a. I'm not sure whether it is worth extending these ranges down to lower bitrates. The work required to switch alloc tables *during* the encoding is major. In the case of silence, it might be worth doing a quick check for very low signals and writing a pre-calculated *blank* 32kpbs frame. [probably also a lot of work]. How CBR works ------------- - Use the psycho model to determine the MNRs for each subband [MNR = the ratio of "masking" to "noise"] (From an encoding perspective, a bigger MNR in a subband means that it sounds better since the noise is more masked)) - calculate the available data bits (adb) for this bitrate. - Based upon the MNR (Masking:Noise Ratio) values, allocate bits to each subband - Keep increasing the bits to whichever subband currently has the min MNR value until we have no bits left. - This mode does not guarentee that all the subbands are without noise ie there may still be subbands with MNR less than 0.0 (noisy!) How VBR works ------------- - pretend we have lots of bits to spare, and work out the bits which would raise the MNR in each subband to the level given by the argument on the command line "-v [int]" - Pick the bitrate which has more bits than the required_bits we just calculated - calculate a_bit_allocation() - VBR "guarantees" that all subbands have MNR > VBRLEVEL or that we have reached the maximum bitrate. FUTURE ------ - with this VBR mode, we know the bits aren't going to run out, so we can just assign them "greedily". - VBR_a_bit_allocation() is yet to be written :) twolame-0.3.13/frontend/0000777000076500000240000000000011516347144012076 500000000000000twolame-0.3.13/frontend/audioin_raw.c0000644000076500000240000000602011507676465014470 00000000000000/* * TwoLAME: an optimized MPEG Audio Layer Two encoder * * Copyright (C) 2004-2007 The TwoLAME Project * * This library is free software; you can redistribute it and/or * modify it under the terms of the GNU Lesser General Public * License as published by the Free Software Foundation; either * version 2.1 of the License, or (at your option) any later version. * * This library is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

This is basically because I was sick of the inconsistencies between the notation in the ISO docs and in the sourcecode. I've nicked a bunch of stuff from LAME to make this a bit easier to grok - ATH values (this also overcomes the lack of mpeg-2 tables which meant that LSF never had proper values) - ath_freq2bark() to convert frequencies directly to bark values. - spreading_function() isolated the calculation of the spreading function. Basically the same code as before, just isolated in its own function. LAME seem to does some extra tweaks to the ISO1117s model. Not really sure if they help or hinder, so I've commented them out (#ifdef LAME) NB: Because of some of the tweaks to bark value calculation etc, it is now possible to have 64 CBANDS. There's no real limit on the actual number of paritions. I wonder if it's worth experimenting with really higher numbers? Probably won't make that much difference to the final SNR values, but it's something worth trying Maybe CBANDS should be a dynamic value, calculated by the psycho_init function CBANDS definition has been changed in encoder.h from 63 to 64 ****************************************************************/ /* The static variables "r", "phi_sav", "new", "old" and "oldest" have to be remembered for the unpredictability measure.

It is based heavily on: - tooLAME by Michael Cheng - the ISO dist10 code - improvement to algorithms as part of the LAME project (lame.sf.net) - other contributors (see AUTHORS) TwoLAME should be able to be used as a drop-in replacement for LAME (a MPEG Layer 3 encoder). The frontend takes very similar command line options to LAME, and the backend library has a very similar API to LAME. For the latest version of TwoLAME, visit the project homepage: http://www.twolame.org/ MPEG Audio Layer 2 (MP2) ------------------------ (taken from Wikipedia article on MP2) MP2 (sometimes incorrectly named Musicam) is a short form of MPEG Audio Layer II, and it is also used as a file extension for files containing audio data of this type. While it has largely been superseded by MP3 for PC and Internet applications, it remains a dominant standard for audio broadcasting as part of the DAB digital radio and DVB digital television standards. It is also used internally within the radio industry, for example in NPR's PRSS Content Depot programming distribution system.

mpglib ? - use 32-bit floats internally where possible twolame-0.3.13/twolame.pc.in0000644000076500000240000000035111507676465012606 00000000000000prefix=@prefix@ exec_prefix=@exec_prefix@ libdir=@libdir@ includedir=@includedir@ Name: twolame Description: An optimized MPEG Audio Layer 2 encoder Requires: Version: @VERSION@ Libs: -L${libdir} -ltwolame Cflags: -I${includedir} twolame-0.3.13/win32/0000777000076500000240000000000011516347143011220 500000000000000twolame-0.3.13/win32/configwin.h0000644000076500000240000000366611507676465013317 00000000000000/* Configuration header file for Win32 */ #include "winutil.h" /* Define if debugging is enabled. */ #ifdef _DEBUG #define DEBUG 1 #else #undef DEBUG #endif /* Define to 1 if you have the header file. */ #define HAVE_ASSERT_H 1 /* Define to 1 if you have the header file. */ #define HAVE_DLFCN_H 1 /* Define to 1 if you have the header file. */ #define HAVE_INTTYPES_H 1 /* Define to 1 if you have the `m' library (-lm). */ #define HAVE_LIBM 1 /* Define to 1 if you have the `mx' library (-lmx). */ #undef HAVE_LIBMX /* Define to 1 if you have the header file. */ #define HAVE_MEMORY_H 1 /* Define to 1 if you have the header file. */ #define HAVE_STDINT_H 1 /* Define to 1 if you have the header file. */ #define HAVE_STDLIB_H 1 /* Define to 1 if you have the header file. */ #define HAVE_STRINGS_H 1 /* Define to 1 if you have the header file. */ #define HAVE_STRING_H 1 /* Define to 1 if you have the header file. */ #define HAVE_SYS_STAT_H 1 /* Define to 1 if you have the header file. */ #define HAVE_SYS_TYPES_H 1 /* Define to 1 if you have the header file. */ #define HAVE_UNISTD_H 1 /* Name of package */ #define PACKAGE "libtwolame" /* The size of a `float', as computed by sizeof. */ #define SIZEOF_FLOAT 4 /* The size of a `short', as computed by sizeof. */ #define SIZEOF_SHORT 2 /* Define to 1 if you have the ANSI C header files. */ #define STDC_HEADERS 1 /* Version information for package */ #define PACKAGE_BUGREPORT "support" #define PACKAGE_VERSION "unknown" /* Define to 1 if your processor stores words with the most significant byte first (like Motorola and SPARC, unlike Intel and VAX). */ #undef WORDS_BIGENDIAN /* Define to `__inline__' or `__inline' if that's what the C compiler calls it, or to nothing if 'inline' is not supported under any name. */ #undef inline #define inline __inline twolame-0.3.13/win32/libtwolame_dll.sln0000644000076500000240000000155511507676465014666 00000000000000 Microsoft Visual Studio Solution File, Format Version 9.00 # Visual C++ Express 2005 Project("{8BC9CEB8-8B4A-11D0-8D11-00A0C91BC942}") = "libtwolame_dll", "libtwolame_dll.vcproj", "{DFB06356-061D-4EAD-82F5-4696149B6F01}" EndProject Global GlobalSection(SolutionConfigurationPlatforms) = preSolution Debug|Win32 = Debug|Win32 Release|Win32 = Release|Win32 EndGlobalSection GlobalSection(ProjectConfigurationPlatforms) = postSolution {DFB06356-061D-4EAD-82F5-4696149B6F01}.Debug|Win32.ActiveCfg = Debug|Win32 {DFB06356-061D-4EAD-82F5-4696149B6F01}.Debug|Win32.Build.0 = Debug|Win32 {DFB06356-061D-4EAD-82F5-4696149B6F01}.Release|Win32.ActiveCfg = Release|Win32 {DFB06356-061D-4EAD-82F5-4696149B6F01}.Release|Win32.Build.0 = Release|Win32 EndGlobalSection GlobalSection(SolutionProperties) = preSolution HideSolutionNode = FALSE EndGlobalSection EndGlobal twolame-0.3.13/win32/libtwolame_dll.vcproj0000644000076500000240000001507611507676465015400 00000000000000 twolame-0.3.13/win32/libtwolame_static.sln0000644000076500000240000000156311507676465015401 00000000000000 Microsoft Visual Studio Solution File, Format Version 9.00 # Visual C++ Express 2005 Project("{8BC9CEB8-8B4A-11D0-8D11-00A0C91BC942}") = "libtwolame_static", "libtwolame_static.vcproj", "{8C69F7B6-684F-48D9-9057-8912CA3DAA8B}" EndProject Global GlobalSection(SolutionConfigurationPlatforms) = preSolution Debug|Win32 = Debug|Win32 Release|Win32 = Release|Win32 EndGlobalSection GlobalSection(ProjectConfigurationPlatforms) = postSolution {8C69F7B6-684F-48D9-9057-8912CA3DAA8B}.Debug|Win32.ActiveCfg = Debug|Win32 {8C69F7B6-684F-48D9-9057-8912CA3DAA8B}.Debug|Win32.Build.0 = Debug|Win32 {8C69F7B6-684F-48D9-9057-8912CA3DAA8B}.Release|Win32.ActiveCfg = Release|Win32 {8C69F7B6-684F-48D9-9057-8912CA3DAA8B}.Release|Win32.Build.0 = Release|Win32 EndGlobalSection GlobalSection(SolutionProperties) = preSolution HideSolutionNode = FALSE EndGlobalSection EndGlobal twolame-0.3.13/win32/libtwolame_static.vcproj0000644000076500000240000001406211507676465016106 00000000000000 twolame-0.3.13/win32/winutil.h0000644000076500000240000000032411507676465013013 00000000000000#ifndef __TWOLAME_WINUTIL_H #define __TWOLAME_WINUTIL_H /* * Don't define this as a function to avoid conflicts * with other libraries which already define this. */ #define lrintf(x) ((int)((x)+0.5)) #endif
