Overview​

Watch Dogs: Legion (and WD2) use Audiokinetic Wwise for audio. Sound data is stored in Wwise SoundBank (.bnk) files within the Disrupt archive system.

WDL SoundBank Version​

WDL soundbanks = Wwise SoundBank version 132 (0x84)

This corresponds to Wwise 2019.2.x.

SoundBank Chunk Structure​

WDL BNKs follow standard Wwise chunk layout:

BKHD (version 132) + DIDX + DATA + HIRC
  • BKHD: Bank header (contains version, ID, etc.)
  • DIDX: Data index (file offsets/sizes for embedded media)
  • DATA: Audio data blob
  • HIRC: Hierarchy (event/action/structure definitions)
