Audio Options (OpenXcom)

OpenXcom default Audio Options

Volume

• Music: Background music played during the game.
• SFX: Sound effects played during the game, except the ones below.
• UI: User interface sounds, like button presses and window popups.

WARNING: When using MIDI music on Windows Vista and later, the music volume slider will actually affect the whole game's volume.

Music Format

OpenXcom supports a variety of music formats, and will automatically pick the best format available in this order:

• FLAC
• OGG
• MP3
• MOD
• WAV
• Adlib
• MIDI

The currently-used format is shown under the option. If you are not happy with its selection, you can use this option to set your own preferred music format.

Original Music

The original game includes different music formats depending on the version:

• DOS 1.0 - Adlib
• DOS 1.4 - Adlib and MIDI
• Windows - MIDI
• Steam - Adlib and MIDI

Custom Music

You can also use custom music (remixes etc.) if you don't like or have trouble getting the original X-COM music to work. Just put it in the SOUND subfolder of the Data folder with the same filenames as the original. Here's a table listing the correspondences between the original and fan soundtracks:
