What is a .nst file?

A .nst file is an amiga SoundTracker audio. Its registered MIME type is audio/x-mod, which places it in the audio family of formats.

NST is a binary format: the contents are not readable text, so opening it in a text editor shows scrambled characters.

The same format is also saved with the extensions .fst, .m15, .mod, .stk.
