MO3 is a file format written by Un4seen, developers of the soundengine BASS, encapsulating the features of several "MOD" formats (IT, XM, S3M, MTM, MOD, MPTM), 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 of this makes it possible to have great reductions in file sizes with practically identical sound quality.

Common file extensions: mo3
