Lossless Audio (La) is a lossless audio compressor developed 2002 to 2004 by Michael Bevin, for the Windows and Linux/x86 platforms.
La is available as closed-source freeware with a graphical front-end and plugins for Winamp/XMMS and foobar2000; its foobar2000 plugin truncates the end of files and should be avoided.
La was - and might still be - the highest compressing lossless encoder, possibly rivaled only by OptimFrog at its highest (and apparently even slower) setting. Both encoding and decoding are CPU-intensive. It is limited to 16 bit input. With the software being closed-source and no format specification available, it is not known whether this is a limitation to the format or to the encoder.
