Music

The original Doom could only play music in a format called MUS. ZDoom can also play these, but it also supports playing MIDI and MOD files and will automatically recognize them. The specific types of MODs that ZDoom supports are the same types supported by the MIDAS Digital Audio System (since ZDoom uses MIDAS for sound):

• 4-channel Protracker modules plus 1-32 -channel variants (.MOD)
• 1-32 -channel Scream Tracker 3 modules (.S3M)
• 2-32 -channel FastTracker 2 modules (.XM)
• 1-64 -channel Impulse Tracker modules (.IT)

Currently, it does not support 2.14 format .ITs, so if you want to use one of them, you will need to convert it with Impulse Tracker.

Large collections of MODs can be found at ftp.wustl.edu/pub/aminet/mods/ and ftp.cdrom.com/pub/demos/music/, but if you want to use any music from those archives, you should check with the song's author(s) first.
