MP3 and MP2 - Others
This page features MP3 and MP2 encoders other than LAME, as well as some encoding tools. Of special interest are Gogo and Helix encoder, which are quite faster than LAME.
Helix mp3 encoder v5.2.3
2024-04-14Helix mp3 encoder modified by 'maikmerten' to include a 'lametag' to provide sample accurate
encoding/decoding for VBR and CBR, plus a bug fix to the original code. Info tag cleanup,
correct bitrate index computation for stereo files. CRC data added.
Further modifications by Case:
* Made encoder reject input tracks with zero samples.
* Added support for printing unicode filenames to the console.
* Fixed gapless data saving, the encoder tried to store too long numbers in
padding info fields and the numbers got truncated as the storage space is only
12 bits long.
* Fixed internal resampling to produce output with correct lengths.
* Fixed encoding WAV files with huge headers.
* Fixed writing empty track when input had unsupported sample rate.
* Added more detailed error message for input file rejection if the audio specs weren't supported.
Plus further updates/fixes by Case: Wave64 support, RF64 support, fix 32-bit overflows
- fix wraparound of 32-bit variables on long inputs
- new parameter "-il" to ignore the source length, automatically enabled for pipe input
- Wave64 support
- RF64 support
A point release consolidating all the updates/bug fixes detailed above.

VS2015 'masm' x32-XP compile should be XP compatible. x32-P4 GCC compile is P4 optimised. A generic GCC x64
compile and a GCC x64-AVX2 compile optimised for AVX2 compatible CPUs.
fpMP3Enc
2009-12-07fpMP3Enc is a multi-threaded version of LAME that uses the Fiber Pool multi-threading framework (click the link to get to the sources). Uses LAME version 3.98.2. Includes x64 compiles for Windows. Also includes a multi-threaded FLAC encoder.
libmpg123 for Mac OS
2004-08-23mpg123 library compiled for Mac OS X, universal binary. Version 1.12.1
GoGo-no-coda 3.13 bundle
2004-05-25GoGo-no-coda is a japanese fork of LAME that focus on speedy encoding, with several internal routines rewritten in assembly language. This bundle includes gogo.exe and gogo.dll compiled with ICL4.5.
MP2 encoder based on CDex' mp2enc.dll
2003?Command line version of the CDex MP2 encoder. Compiled with ICL6.
twoLame 0.4.0 Release
2021-04-07The fork of the tooLAME project. This uses the libsndfile 1.0.25 dll for input which is included. This is a win32 compile.
twoLame 0.3.12b Release
2008-05-01The fork of the tooLAME project. This is a custom version that does NOT use libsndfile for input. It uses its own native input routines. It will accept 8, 16, 24, 32 bit integer and float wave files as input and will also accept input from 'stdin' - which was really the point in doing it. This is a win32 compile.
Special Wack v0.30 Bundle
2005-05-21An easy-to-use script and application package for encoding LAME --preset standard MP3s using --scale, with integrated tagging, all from within EAC. Includes all the required applications. Complete set up instructions are included. Wack can be used with other encoders, but this package is tailored for the above purpose.
