[Use when]

You need to convert Wwise soundbank (.bnk) files between versions 88, 113, and 145 used in Diesel engine games (PAYDAY 2, RAID: World War II) so older banks load correctly in a newer runtime.

about

A .NET library and CLI tool for reading and converting Wwise soundbank (.bnk) files across the three Wwise versions found in Diesel engine titles: version 88 (2013), 113 (2015), and 145 (2022). It parses the major section headers—BKHD, STMG, DATA, DIDX, HIRC, ENVS, STID—and within HIRC handles a broad set of object types including Actions, Actor Mixers, Attenuations, Audio Devices, Buses, Events, FX Share Sets, Layer Containers, Music Random Sequence Containers, Music Segments, Music Switches, Music Tracks, Random Sequence Containers, Sounds, and Switch Containers.

The converter migrates soundbanks from an older version to a newer one so assets authored against an older Wwise SDK can be loaded by a newer Diesel build. The library exposes an in-memory object model inspectable via any IDE's object inspector, and an accompanying ImHex pattern is provided for raw binary exploration. Format reading was written using bnnm's wwiser as reference.
