About BWAV
BWAV is the wave format of Nintendo's newer sound tools, which its own Switch games use for voices, effects and music, often many of them packed into one archive. Its name says WAV, but it isn't one, and media players don't know it.
A BWAV holds a sound in Nintendo's DSP-ADPCM, 4 bits a sample, or PCM, one channel after another, each with its own coefficients and loop, so a sound plays on seamlessly for as long as the game needs it.
Filepeek plays a BWAV in your browser with vgmstream, twice through its loop and then a fade, with its waveform, speeds and tags, and Export saves it as MP3 or WAV.

Questions
How do I play a BWAV file?
Drop it on this page or choose Peek a BWAV. It plays in your browser, twice through its loop and then a 5 second fade, the way a game loops its music.
Can I turn a BWAV into an MP3?
Yes. Choose Export, then Save as MP3 or WAV, and the sound is saved as it plays here, loop and fade included.
Is a BWAV a WAV?
No. It's Nintendo's own format, holding DSP-ADPCM that WAV players don't know. Saved here as a WAV, it plays anywhere.
