Revision as of 15:22, 5 January 2019

This is the binary version of the XACT SoundBank (XSB), version 11, as used by Jade Empire on the original Xbox. The Windows PC version of Jade Empire uses an ASCII variant, which contains the same information.

Conceptually, it's very similar to later XSB versions that are used by Microsoft's XNA toolset.

On the top-level, a SoundBank consists of cues and sounds. A sound is a collection of tracks, which each contain a list of events and a list of wave variations, while a cue consists of a list of references to sounds.

A structural example

  • Sounds
    • Sound 0
      • Track 0
        • Event list
          • PLAY
          • LOOP
          • VOLUME
          • PITCH
        • Wave variations
          • Sound 23 out of WaveBank "foobar"
          • Sound 24 out of WaveBank "foobar"
          • Sound 12 out of WaveBank "quux"
    • Sound 1
      • Track 0
        • Event list
          • PLAY
        • Wave variations
          • Sound 24 out of WaveBank "foobar"
      • Track 1
        • Event list
          • PLAY
        • Wave variations
          • Sound 25 out of WaveBank "foobar"
  • Cues
    • Cue 0
      • Cue variations
        • Sound 0
        • Sound 1
    • Cue 1
      • Cue variations
        • Sound 0
    • Cue 2
      • Cue variations
        • Sound 1

Both the cue variation and the wave variation can be selected using different methods. For example, they could be played in order, or randomly. Or they could be explicitly selected by game.

Structures

All numerical values are little-endian.
