About WEM
Wwise is Audiokinetic's sound engine, which game studios have used since 2006 for everything a game plays, from footsteps to its music, in games like Overwatch, Cyberpunk 2077 and Genshin Impact. Each sound Wwise builds for a game is a WEM, named by a number rather than a title.
A WEM is a RIFF file, like a WAV, holding a codec of Audiokinetic's own: most often its own Vorbis, cut down from Ogg Vorbis, or ADPCM, PCM, Opus, ATRAC9 on PlayStation or XMA on Xbox. Its loop points say where the music starts over, so a track plays on for as long as a level lasts. Media players don't know these codecs, so a WEM won't play outside its game.
Filepeek plays a WEM in your browser with vgmstream, the library game music players are built on, twice through its loop and then a fade, with its waveform, speeds and tags. Export saves it as MP3 or WAV. Wwise's Vorbis, ADPCM, PCM, ATRAC9 and the Wii U's DSP play with their loops, and its Opus, AAC, WMA and the Xbox's XMA2 play once through.

Questions
How do I play a WEM file?
Drop it on this page or choose Peek a WEM. 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 WEM 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.
Why is my WEM named with a number?
Wwise names each sound by an ID made from its name in the game's project and leaves the names out of the game. The game's banks say which event plays which number.
Why won't some WEM files play?
Most do. Wwise's Opus, AAC, WMA and the Xbox's XMA2 play once through, without their loops, and a WEM in a codec Filepeek doesn't play says so.
Where are a game's WEM files?
Loose in its folders, or inside its .pck packages and .bnk banks, which Filepeek opens as folders of their sounds.
