XM, standing for "extended module", is an audio file type introduced by Triton's Fast Tracker 2. XM introduced multisampling-capable instruments with volume and panning envelopes, and basic sample compression. It also expanded the available effect commands and channels, added 16-bit sample support, and offered an alternate frequency table for portamentoes.

Common format for many Chiptunes.
