LAME is a high quality MPEG Audio Layer III (MP3) encoder licensed under the LGPL.

Latest LAME release: v3.100(October 2017)

LAME development started around mid-1998. Mike Cheng started it as a patch against the 8hz-MP3 encoder sources. After some quality concerns raised by others, he decided to start from scratch based on the dist10 sources. His goal was only to speed up the dist10 sources, and leave its quality untouched. That branch (a patch against the reference sources) became Lame 2.0, and with Lame 3.81 all of dist10 code was replaced, making LAME no more only a patch.

Libmp3lame.dll, File description: MP3 Encoder. Errors related to libmp3lame.dll can arise for a few different different reasons. For instance, a faulty application, libmp3lame.dll has been deleted or misplaced, corrupted by malicious software present on your PC or a damaged Windows registry.

The project quickly became a team project. Mike Cheng eventually left leadership and started working on tooLame, an MP2 encoder. Mark Taylor became leader and started pursuing better quality in addition to increased speed. He can be considered the initiator of the LAME project in its current form. He released version 3.0 featuring gpsycho, a new psychoacoustic model he developed.

In early 2003 Mark left project leadership, and since then the project has been lead through the cooperation of the active developers (currently three individuals).

Today, LAME is considered the best MP3 encoder at mid-high bitrates and at VBR, mostly thanks to the dedicated work of its developers and the open source licensing model that allowed the project to tap into engineering resources from all around the world. Both quality and speed improvements are still happening, probably making LAME the only MP3 encoder still being actively developed.

  1. I would not bother. The installer puts libmp3lame in /usr/local/lib/audacity. If Audacity has not detected libmp3lame.dylib there itself when you open the Audacity Preferences then the Mac is locking out /usr/local/lib/audacity, as it often does.
  2. To enable MP3 on LadioCast 0.12+.In this example, the mp3 encoding library file libmp3lame.0.dylib was installed by the package from
  3. A dylib is a dynamic library ready to run it is not compressed. Here are some instructions I have found on the Audacity site: 'Once you have unzipped the archive, you will have a file called LameLib or libmp3lame.dylib.
  4. A dynamic link library/shared object: lameenc.dll on Windows, on Linux and Solaris, libmp3lame.dylib on Mac OS X. This library exports the standard LAME API as declared in lame.h. The Windows version (lameenc.dll) exports the API too, this API is backward compatible with the old BladeEnc MP3 encoder.

In this site, and you will find Audacity-compatible plug-ins and libraries such as those needed forMP3 Encoding, or the FFmpeg library for wider file format support. This siteis NOT affiliated with Audacity(R) in any other way than by compatibility withit.

LAME is a library that allows some programs to encode MP3 files.LAME is free,but in some countries you may need to pay a license fee in orderto legally encode MP3 files.

Audacity is a free and open source Audio Editor which allows you totransform ogg to mp3, transform mp3 to ogg, transform vinyls to mp3 or ogg, do anykind of home recording, remove noise, etc. Is WONDERFUL. I have used it torecord and mix some of my bands songs. Feel free to check out this page to download some songs.

To use LAME (or FFmpeg) with Audacity, you can put it anywhereyou want, but the first time you want to export an MP3 file,Audacity will ask you for the location of this file, so you willwant to remember where you put it.
