file extension IMF - Apogee IMF audio file format
File extension IMF description:
MF is an audio file format created by id Software for the AdLib sound card for use in their video games. The default filename extension is also "imf". The abbreviation stands for "id music file" or "id's music format".The format is similar to MIDI, in that it defines musical notes, and does not support sampled digital audio for sound effects. IMF files store the actual bytes sent to the AdLib's OPL2 chip, which uses FM synthesis to produce audio output. The format is based on the AdLib command syntax, with a few modifications. Due to the limited features and relatively low sound quality, modern games no longer use IMF music.
Games using IMF music include: Bio Menace, Blake Stone: Aliens of Gold, Blake Stone: Planet Strike, Catacomb 3-D, Commander Keen 4-6, Corridor 7, Cosmo's Cosmic Adventure, Duke Nukem II, Major Stryker, Monster Bash, Operation Body Count, Spear of Destiny, and Wolfenstein 3D.
