About BNK
A game made with Wwise loads its sounds in banks. A BNK holds the events the game calls, like a footstep or a menu click, the sounds behind them and how they mix, and often the sounds themselves, as WEM files inside it.
Its sections each start with a four letter name: BKHD for the bank's header, DIDX and DATA for the WEMs it holds, and HIRC for its events and objects, each named by a number. Many banks hold only events, their sounds in .wem files of their own or in the game's .pck packages.
Filepeek opens a BNK as a folder of the sounds inside it, each named by its number, and the one you pick plays at once with vgmstream, twice through its loop and then a fade. Export saves it as MP3 or WAV, and Save as ZIP or Extract all saves every sound as a WAV.

Questions
How do I get the sounds out of a BNK file?
Drop it on this page or choose Peek a BNK. Its sounds are listed like the files in a folder, and Save as ZIP or Extract all saves each one as a WAV.
Can I turn a sound from it into an MP3?
Yes. Pick it, choose Export, then Save as MP3 or WAV, and it's saved as it plays here, loop and fade included.
Why does Filepeek say my BNK holds no sounds?
Many banks hold only the game's events, their sounds in .wem files beside them or in its .pck packages. Those open on their own, each sound playing as it is.
Why are the sounds named with numbers?
Wwise names each sound by an ID made from its name in the game's project and leaves the names themselves out of the game.
