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 and often surpass 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, see: Software which uses LAME.

Using the LAME encoding engine (or other mp3 encoding technology) in your software may require a patent license in some countries.

LAME features:

* Many improvements in quality in speed over ISO reference software. See history.
* MPEG1,2 and 2.5 layer III encoding.
* CBR (constant bitrate) and two types of variable bitrate, VBR and ABR.
* Encoding engine can be compiled as a shared library (Linux/UNIX), DLL , Directshow filter or ACM codec (Windows).
* Free format encoding and decoding.
* GPSYCHO: a GPL'd psycho acoustic and noise shaping model.
* Powerful and easy to use presets.
* Quality better than all other encoders at most bitrates.
* Fast! Encodes faster than real time on a PII 266 at highest quality mode.
* MP3x: a GTK/X-Window MP3 frame analyzer for both .mp3 and unencoded audio files.

LAME 3.98 Beta 5 (August 12, 2007):

* Jonathan Stott:
o Bug tracker items: [ 1590693 ] ID3v2 tag not writing, [ 1636267 ] ID3v2 tags overwritten
If the output file is opened 'write-only', then LAME can't update the LAME tag. In this case LAME silently overwrote the first bytes of the file and an optional ID3v2 tag disappeared. Now an error message will be printed and no data is written in this case.
* Robert Hegemann:
o Fix for Bugtracker item [ 1719593 ] Track numbers > 255 not allowed even with --id3v2-only
o Fix for Bugtracker item [ 1742623 ] fail(lame --mp3input -m m -b 128 --resample 8 *.mp3 **.mp3)
The problem here was, the input files are MPEG-1 Layer2 files named as MP3s. Even if you leave out the --mp3input switch LAME tried to decode the input files as Layer3 files because of the file name extension and because it found some valid looking Layer3 synchronization header. The fixed LAME version does not assume the file name extension is always correct and treats the files depending on the first found MPEG sync word. The files in question are now correctly detected as Layer2 files and transcoding does succeed.
o Fix for Bugtracker item [ 1445175 ] Input being stdin fails in Windows on WAV files
The problem here was, seeking on pipes shows some different behaviour depending on C-Library implementations. The workaround tries to detect it's working on a pipe and doing some reading instead of seeking in that case.
o Fixing some memory leak in the 'lame_enc.dll'.
o Fix for Bugtracker items [ 1160757, 1160741 ] --little-endian / --big-endian not working
These switches where originally intended to be used together with Libsndfile only.
o Fix for Bugtracker item [ 1746336 ] Incorrect Bitrate with ABR und --resample, LAME 3.98b4
Some earlier bug-fix had some typo. As a result, when adding a '--resample 123' switch, the average bitrate rised upto maximum bitrate.
