Following the great history of GNU naming, LAME originally stood for LAME Ain't an Mp3 Encoder. ** LAME started life as a GPL'd patch against the dist10 ISO demonstration source, and thus was incapable of producing an mp3 stream or even being compiled by itself.** But in May 2000, the last remnants of the ISO source code were replaced, and now LAME is the source code for a fully LGPL'd MP3 encoder, with speed and quality to rival all commercial competitors.
LAME is an educational tool to be used for learning about MP3 encoding.* The goal of the LAME project is to use the open source model to improve the psycho acoustics, noise shaping and speed of MP3. LAME is not for everyone - it is distributed as source code only and requires the ability to use a C compiler.* However, many popular ripping and encoding programs include the LAME encoding engine
