Sound File Formats
The Dark Mod is using the following standards:
- SFX: Ogg, 44100Hz, 96kbps, mono
- Ambient: Ogg, 44100Hz, 160kbps, stereo OR Ogg, 44100Hz, 96kbps, mono. (Does the sound really benefit from stereo format?)
Doom 3 supports 1 or 2 channel, 16 bit OGG or WAV files at 11025, 22050 or 44100 Hz.
If making your own recordings use some lossless format like FLAC and only then convert them to OGG. Converting them first (with probably bad compression options, too) to MP3, then recompressing to OGG will introduce unnec. compression artefacts.
