What is a DTM file?
A DTM file is a Dolphin TAS movie created by Dolphin, an emulator used to play GameCube and Wii games. It contains controller input data used to recreate a gameplay recording. DTM files do not store actual video.
You can create DTM files in Dolphin by selecting Emulation → Start Recording. The DTM file is created to store data such as the game ID, recording start time, controller input data, and other in-game settings.
You can use the Dolphin emulator to view the DTM file. You can also use DTM Editor (only for GameCube controller data) to edit the buttons, triggers, D-Pad , and stick positions for each frame.

A DTM file may also be an audio tracking module saved in the Digital Tracker Module (DTM) format, a proprietary format used by the Digital Tracker audio application. It contains note patterns and sound samples representing different instruments played back according to the notes.
Frontier Software developed Digital Tracker and released it in 1994 for the Atari Falcon computer. Its DTM format is based on the .MOD Amiga Module format that Karsten Obarski developed and released with the Ultimate Soundtracker software for the Commodore Amiga system in 1987.
If you encounter a DTM file, a Digital Tracker user most likely created it on an Atari Falcon computer. However, an audio tracker enthusiast may have created the file with another audio tracker program that supports the format.
