To keep it from being confused with LAME 3.93 alpha versions, the code was made to self-identify as LAME 4.0 alpha 1 (in late 2002) through 4.0 alpha 14 (since 2005). One of these branches was started after the release of LAME 3.92 in 2002. There are also numerous experimental branches of this code in which the developers test new ideas. LAME source code is maintained in a CVS repository, and the only official codebase for public use is the trunk code tagged 'MAIN'. Descriptions of patents are in the public domain.' The LAME project's position is 'Source code is considered as speech, which may contain descriptions of patented technology. When the source code is compiled and distributed, it may require a license from Thomson, depending on where and how it's to be used. Development is ongoing.Īlthough LAME is generally considered to be an encoder, according to the LAME technical FAQ, it's technically not an encoder, but rather is officially just 'a development project which uses the open source model to improve MP3 technology.' This improved technology is only released in source code form in order to minimize the risk of violating patents. Nowadays LAME is considered the best MP3 encoder at mid & high bitrates, and features the best VBR model among MP3 implementations, mostly thanks to the dedicated work of talented developers Takehiro Tominaga, Naoki Shibata, Darin Morrison, Gabriel Bouvigne, Robert Hegemann, and others. Mark Taylor became leader and released version 3.0 featuring gpsycho, a new psychoacoustic model developed by him. Mike Cheng eventually left leadership and started working on tooLAME, an MP2 encoder.

The project quickly became a team effort. By the release of LAME 3.81, all dist10 code was removed, making LAME a completely new program, not a mere patch of an existing encoder. That branch (a patch against the reference sources) became LAME 2.0. After some quality concerns raised by others, he decided to start from scratch based on the dist10 sources. Mike Cheng started it as a patch against the 8hz-MP3 encoder sources.

5.5 Hey! What happened to '-alt-preset'?.

3.5 Very low bitrate, small sizes: eg.3.4 Portable: listening in noisy conditions, lower bitrate, smaller file size.3.3 Very high quality: HiFi, home, or quiet listening, with maximum file size.3.2 Very high quality: HiFi, home, or quiet listening, with best file size.2 Recommended encoder compiles and source code.
