DMX is an sound effect format created by Paul Radek for his DMX audio library. This library is best known for powering the audio in Doom (DOS) and related games. The format has multiple structures depending on the intended output device including a PCM format for voice and digital sound effects, a GSS format for MIDI and AdLib sound effects, and a PSG format for PC Speaker sound effects. While the Doom engine games didn't take advantage of GSS sound effects (though Doom engine itself support them), they can be heard in later games like Raptor: Call of the Shadows (DOS).
