Audio

Dwarf Fortress contains music tracks which play at various points in game, including the main menu theme. Some types of audio seem to be triggered by events, while others play randomly while certain criteria are met. These seem to include some weather sounds, wild ambience, building sounds, river etc.

According to Tarn, there are different settings for every track. One depends on the caverns being opened, one plays only after the second year, one is a first year track. Strike the Earth plays when you first embark, and then gets mixed in with the others afterward. And so forth; there's a raw format for this so you can change it if you like.[1]

Game Audio settings can be adjusted in the settings menu.

Modding

All sound and music files used by Dwarf Fortress are stored in the .ogg format within the <Dwarf Fortress>/data/sound/ subfolders. You can replace the existing ogg files with different ones. That has to be performed manually and isn't actually supported by the game. You can also change some of the definitions of when certain musical cues are played, using available music tokens and sound tokens in the raw files found in <Dwarf Fortress>\data\vanilla\vanilla_music\. You can add new music and sounds with raws in the sound folder^v0.50.09, formatted like so:

Identifiers

To allow the game to read sound files consistently, they must be given an identifier. Identifiers can be any arbitrary string, just like any other raw object. Files containing identifiers are stored in a mod's sound/ directory (not the objects/ directory, where the logic for playing them is stored), and their name must start with sound_file_ or music_file_. Their first line must be the filename, followed by [OBJECT:SOUND_FILE] or [OBJECT:MUSIC_FILE] respectively.

sound_file_example
[OBJECT:SOUND_FILE]
[SOUND_FILE:<identifier>]
    [FILE:file name]

music_file_example
[OBJECT:MUSIC_FILE]
[MUSIC_FILE:<identifier>]
    [FILE:file name]
    [AUTHOR:author name]
    [LOOPS] optional
    [TITLE:piece title]

LOOPS		(Music only) If set, should play continuously until interrupted. [verify]
TITLE	string	(Music only) Displays as track title on pause menu.

Sound effects

All vanilla sound tokens are found within sound_standard.txt. All sound definition files must begin with sound_, followed by the [OBJECT:SOUND] token that tells the game that the file contains sound definitions.

[SOUND:<identifier>]
    [FILE:<file identifier>]
    [ANNOUNCEMENT:<announcement>]
    ...
    [ANNOUNCEMENT:<announcement n>]

Token	Arguments	Extra Information

Music tracks

All vanilla music tokens are found within music_standard.txt. All music files must begin with the file name^[Verify], followed by the [OBJECT:MUSIC] token that tells the game that the file contains music definitions.
