About PCK
Wwise packs a game's sound banks and streamed sounds into file packages, so the game reads a few large files instead of thousands of small ones. Games ship them as .pck files, often one for the music and effects and one for each language its voices are in.
A PCK starts with AKPK and the tables of what it holds: its languages, then its banks (.bnk) and its streamed sounds (.wem), each named by a number and stored as it is, one after another.
Filepeek opens a PCK as a folder, its music and effects at the top and each language's voices in a folder of their own. A sound plays at once with vgmstream, twice through its loop and then a fade, and a bank opens as a folder of its own sounds. Save as ZIP or Extract all saves every bank and sound as it is.
Godot games keep their files in a .pck too, which starts with GDPC instead. Filepeek opens one as a folder of the game's scenes, scripts, textures and sounds, beside a page with the Godot version that made it, the game's name and first scene and the pictures inside its imported textures. A pack encrypted with the game's key only says so.

Questions
How do I open a PCK file?
Drop it on this page or choose Peek a PCK. It opens like a folder of its banks and sounds, and each sound plays when you pick it.
Can I get the sounds out as MP3?
Yes. Pick a sound, choose Export, then Save as MP3 or WAV. Save as ZIP or Extract all saves every bank and sound inside as it is.
Is every PCK a Wwise package?
No. Godot games keep their files in .pck packs too. Filepeek tells them apart by their first bytes and opens a Godot pack as a folder of the game's files, with a page of the Godot version, the game's name and its pictures.
Why doesn't a sound play?
Wwise can pack sounds in Opus, or XMA on Xbox, which Filepeek doesn't play, and it says so.
