What is a MO3 file?

MO3 files mostly belong to XMPlay. MO3 files are a type of tracker audio file format that use compression to store music data efficiently.
They combine uncompressed pattern data with compressed sample data, keeping the file size smaller while still preserving the arrangement and playback instructions used in tracker music.
This file format is mainly used to hold music created for or by tracker programs. It is supported by players like XMPlay and OpenMPT. When playing an MO3 file, the software decompresses the sample data on the fly while reading the unchanged module patterns.
