What is a MO3 file?

An MO3 file is an audio module saved in a variant of the standard .MOD format. Unlike MOD files, MO3 files are compressed using MP3 or Ogg Vorbis audio compression. For this reason, MO3 files typically have smaller file sizes than MOD files.

More Information

While MO3 files are uncommon, those immersed in the music tracker scene may encounter them. Un4seen Developments created the MO3 file format to allow music tracker users to compress modules saved in the MOD format (and variants, such as .IT, .XM, .S3M, and .MTM).

Typically, music tracker users use the following encoders to compress MOD files (or other audio modules) into MO3 files:

  • Rarewares LAME, to create MP3-compressed MO3 files
  • OGGENC, to create Ogg Vorbis-compressed audio files
