About FSB
FMOD is Firelight Technologies' sound engine, which thousands of games play their sounds with, and the audio inside Unity is built on it too. FMOD packs a game's sounds into FSB sound banks, and Unity keeps its games' audio clips as FSBs inside their .resource files.
An FSB starts with FSB and its version, 2 to 5, and holds its sounds in one codec, each with its rate, channels, loop and usually its name: Vorbis, MP3, ADPCM, PCM, CELT, ATRAC9 on PlayStation or XMA on Xbox. Some games encrypt their FSBs, header and all, with a key of their own.
Filepeek opens an FSB as a folder of its sounds, named as the bank names them, 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. XMA and Opus don't play, and an encrypted FSB says so.

Questions
How do I get the sounds out of an FSB file?
Drop it on this page or choose Peek an FSB. 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 it say my FSB is encrypted?
Some games encrypt their FSBs with a key of their own, header and all. Filepeek carries no game's keys and takes none, so those don't open.
Why are some sounds missing from the list?
Sounds in XMA or Opus, which Filepeek doesn't play, stay out of the list.
