MO3 is a file format, encapsulating the features of several "MOD" formats (IT, XM, S3M, MTM, MOD), but with one big difference - MP3 and OGG compressed samples. A lossless codec is also incorporated for any samples that don't like lossy encoding, and the whole file structure is compressed too.

All this makes it possible to have great reductions in file sizes with practically identical sound quality. Actually MO3 allows greater quality compositions because MP3/OGG encoding works best with 16-bit samples, so there's no reason to use low quality 8-bit samples anymore.

Here are some key features of "MO3":
MP3/OGG compression

- any command-line MP3 or OGG encoder can be used with the MO3 encoder

Lossless compression

- samples that don't compress well with MP3/OGG can still be reduced in size

Structure compression

- all the non-sample data is also compressed

Sample specific config

- the encoding sample/bit rates are individually adjustable for each sample

Text removal

- message/instrument/sample texts can optionally be removed

Decompression

- MO3 files can be decoded back to their original formats using UNMO3

Playable

- MO3s can be played by XMPlay and software that uses the BASS library or UNMO3
