<nowiki>==History==</nowiki>
 
LAME development began 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. That branch (a patch against the reference sources) became LAME 2.0, and only on LAME 3.81 they got rid of all dist10 code, making LAME a completely new program-not a mere patch of an existing encoder.
 
The project quickly became a team effort. Mike Cheng eventually left leadership and started working on tooLAME, an MP2 encoder. Mark Taylor became leader and released version 3.0 featuring gpsycho, a new psychoacoustic model developed by him.
 
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 like Takehiro Tominaga, Naoki Shibata, Darin Morrison, Gabriel Bouvigne, Robert Hegemann, etc. And development is still going on...

Some more details, history and examples about joint stereo & mid/side coding:
The project quickly became a team effort. Mike Cheng eventually left leadership and started working on tooLAME, an MP2 encoder. Mark Taylor became leader and released version 3.0 featuring gpsycho, a new psychoacoustic model developed by him.


mid/side can be lossless like obviously in Lossless formats Flac, Wavpack, Monkey's Audio (ape) etc., but in lossy encoders the encoder tries to do the best to minimize all losses in perception. And here the encoder has not only to deal with stereo modes, but also with mids, highs etc. etc.
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 like Takehiro Tominaga, Naoki Shibata, Darin Morrison, Gabriel Bouvigne, Robert Hegemann, etc. And development is still going on...
So, regarding lossy formats like MP3 (Lame, Fraunhofer, Xing), Musepack (MPC), Vorbis etc., the mid/side coding might be even mathematical lossless, might be perceptual lossless (=transparent), or not so lossless at all at low bitrates.
So, it depends in the lossy formats about the quality of mid/side (js) coding.
From obvious bad sounding bugs like in some old Fraunhofer mp3 ("Radium hack"), not so optimized perfomance like in mp3-Xing, up to the optimized js-modes in mp3-Lame, which offer frame-dependent stereo or mid/side coding to achieve maximum qualities. And advanced formats like mp3-lame, Musepack-MPC or Vorbis-ogg offer increasing js(mid/side//stereo)qualities in increasing general quality (q) levels, examples:
Mp3-Lame inside the presets eg. -V quality levels, with different -msfix values up to the "nssafejoint" mode in 320 kbit cbr.
Musepack-MPC inside the various q-levels/presets and the --ms x switch.
Vorbis in its presets, 1 example above q6 the "lossless stereo coupling".

==Recommended encoder settings==

This section describes the Hydrogenaudio recommended settings to be used with LAME for highest quality MP3 encoding.

These settings require LAME 3.94 or later. LAME 3.97beta3 is the recommended version.

Avoid using alpha (a) versions of LAME. More often than not those are exclusively for testing purposes. Use them only if you want to help developers with feedback.

(...)

===VBR (variable bitrate) settings===

'''[[VBR]]:''' ''variable bitrate mode. Use variable bitrate modes when the goal is to achieve a fixed level of quality using the lowest possible bitrate.''

VBR is best used to target a specific quality level, instead of a specific bitrate. The final file size of a VBR encode is less predictable than with ABR, but the quality is usually better.
