Module file
family of file formats
Module file (MOD music, tracker music) is a family of music file formats originating from the MOD file format on Amiga systems used in the late 1980s. Those who produce these files (using the software called music trackers) and listen to them form the worldwide MOD scene, a part of the demoscene subculture.
The mass interchange of "MOD music" or "tracker music" (music stored in module files created with trackers) evolved from early FIDO networks. Many websites host large numbers of these files, the most comprehensive of them being the Mod Archive.
Nowadays, most module files, including ones in compressed form, are supported by most popular media players such as VLC, Foobar2000, Exaile and many others (mainly due to inclusion of common playback libraries such as libmodplug for gstreamer).
Structure
Module files store digitally recorded samples and several "patterns" or "pages" of music data in a form similar to that of a spreadsheet. These patterns contain note numbers, instrument numbers, and controller messages. The number of notes that can be played simultaneously depends on how many "tracks" there are per pattern. And the song is built of a pattern list, that tells in what order these patterns shall be played in the song.
A disadvantage of module files is that there is no real standard specification in how the modules should be played back properly, which may result in modules sounding different in different players, sometimes quite significantly so.
Begin with the source’s own compact description: “Module file” is family of file formats. The dossier treats that line as a proposition to test through Module, file and family, not as a finished interpretation.
Why this record matters
The phrase “family of file formats” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 20, 2026. The linked authority identifier is Q771510.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
