![]() Some software is released using this strategy: companies use the LAME library, but obtain patent licenses. At the same time, they advise users to obtain a patent license for any relevant technologies that LAME may implement before including a compiled version of the encoder in a product. The LAME developers state that, since their code is only released in source code form, it should only be considered as an educational description of an MP3 encoder, and thus does not infringe any patent by itself when released as source code only. Distributing compiled binaries of LAME, its libraries, or programs that derive from LAME in countries that recognize those patents may be patent infringing. The developers of LAME do not themselves license the technology described by these patents. Like all MP3 encoders, LAME implements some technology covered by patents owned by the Fraunhofer Society and other entities. May 2007: default variable bitrate encoding speed is vastly improved.LAME no longer requires user to use complicated parameters to produce good results. December 2003: substantial improvement to default settings, along with improved speed.LAME is not a patch anymore, but a full encoder. May 2000: the last pieces of the original ISO demonstration code are removed.November 1999: LAME switches from a GPL license to an LGPL license, which allows using it with closed-source applications.Soon after this, LAME also became able to target lower sampling frequencies from MPEG-2. June 1999: The first variable bitrate implementation is released.May 1999: a new psychoacoustic model (gpsycho) is released along with LAME 3.0.LAME Mp3 Info Tag revision 1 SpecificationsĪ few key improvements, in chronological order:.LAME library for Audacity – recommended for the Audacity free and GPL audio editor.Mark Taylor then started pursuing increased quality in addition to better speed, and released version 3.0 featuring gpsycho, a new psychoacoustic model he developed. Mike Cheng eventually left leadership and started working on tooLAME (an MP2 encoder). The project quickly became a team project. That branch (a patch against the reference sources) became Lame 2.0. His goal was only to speed up the dist10 sources, and leave its quality untouched. After some quality concerns raised by others, he decided to start again from scratch based on the “dist10″ MPEG reference software sources. Around mid-1998, Mike Cheng created LAME 1.0 as a set of modifications against the “8Hz-MP3″ encoder source code. The name LAME is a recursive acronym for “ LAME Ain’t an MP3 Encoder”. LAME is a free software codec used to encode/compress audio into the lossy MP3 file format. ![]()
