Metroid Prime 3 InGameAudio.pak by Friendly Blob at 2:48 AM EST on November 25, 2012
I was poking around for the few jingles and other tracks not found in Metroid Prime 3 main audio directory. Apart from a few bits stuck in THPs, I have to assume that the missings are in InGameAudio.pak.
Extracted, I get CAUD and CSMP files, as well as one ATBL and a few DGRP. ATBL is system-related, and DGRP probably is as well. The names are just 0_ and 1_ followed by lots of hexadecimal.
Does anyone happen to know anything about CSMP and CAUD? Is one or both sound effects instead of stream? The CAUD files have text in them like samus_land_metal_heavy that appear to describe sound effects, but seem awfully small to be any kind of audio. Then again, I know next to nothing about SFX. The CSMP files don't give me any indication what they're for.
Not much hope of ever getting usable audio out of them, but I'd like to know more.
(I know this is quite a bump, but) I know for a fact that Dolphin can emulate the CSMP audio properly. If I had the programming skills, I'd go into the Dolphin source code and find the correct algorithms there for interpreting CSMP files, but alas I do not have said skills.
And I know for a fact that the CSMP files are the audio files, because I could just barely make out the audio behind all the noise of incorrect decoding when I imported it into Audacity as raw audio. (Case in point: my not-so-successful, but leading-in-the-right-direction, trials with what is definitely the title/menu theme.)
So, can someone perhaps make some kind of CSMP file decoder? (Or, if anyone has such a thing already, could you share it?)

In other words:
Can someone please provide a solution for decoding CSMP files directly? It would be highly appreciated :)
