Heya!

I'm currently trying to extract Metroid Prime Hunters: First Hunt's music, but it's not going as well as I'd hoped.
Here's one of the raw files I extracted from the ROM filesystem's BGMDATA.BIN: https://i.peterwunder.de/BGMDATA_0005D4AB.raw
Here's what I managed to salvage using sox: https://i.peterwunder.de/BGMDATA_0005D4AB.wav

(and here's how i did it)

sox -t vox -e signed-integer -b 4 -r 11025 -c 1 BGMDATA_0005D4AB.raw -r 44100 -b 16 BGMDATA_0005D4AB.wav

And finally, here's how it's supposed to sound: https://www.youtube.com/watch?v=ZpeBEgH53Qs

All I know about the raw file is that it has 4 bits per sample, 11025 samples per second, and only one channel.
It's probably ADPCM-related, but Audacity has no idea what to do with it and I've officially run out of ideas.

Is anyone here a file format wizard?
