Free online MTM to WAV converter

Source format: MTM

MTM is a module music format used mainly in the demoscene and on older DOS/PC systems. It stands for MultiTracker Module and was created for the MultiTracker tracker application. An MTM file stores pattern-based music data rather than recorded audio, including notes, instruments, and playback instructions. It is typically used for retro game music, demo productions, and archival playback of tracker compositions.

Target format: WAV

WAV is a widely supported uncompressed audio format developed by Microsoft and IBM. It is commonly used for editing, mastering, archiving, and compatibility with nearly all audio software and operating systems. Compared with tracker modules, WAV contains a rendered audio recording, so it can be played without a tracker player and is easy to import into editors, DAWs, and media players.

How to perform the conversion

The best way to convert MTM to WAV is to render the module with a tracker-capable player or audio converter, because MTM is not a recorded sound file. A reliable desktop option is OpenMPT, which can open many module formats and export them as WAV.

1. Install OpenMPT on Windows.
2. Open the .mtm file in OpenMPT.
3. Check that the module plays correctly and that the instruments are loaded properly.
4. Choose File → Export → Wave or File → Export → WAV depending on the version.
5. Select the desired sample rate, channels, and bit depth.
6. Save the exported .wav file.

If you prefer a simpler workflow, you can also convert the file on 101convert.com for free without installing any software, using its built-in online converter.

Notes on quality and limitations

MTM to WAV conversion is a rendering process, so the output quality depends on the player, mixer settings, and instrument samples used in the module. If the original MTM relies on specific tracker effects or old playback behavior, different software may produce slightly different results. For best fidelity, use a converter that supports accurate module playback and export at a high sample rate such as 44.1 kHz or higher. Because WAV is uncompressed, the resulting file will usually be much larger than the MTM source.
