A list of its functions can be found here.
From what it looks, it was written in C and C++ and assembled with GCC.
Stay tuned for more stuff.
See the list here (courtesy Wikipedia).
As we don't know who compiled the US build of Pikmin, we cannot determine who has the library, and even asking them about it would result in no response.
We can, however, wait for a Gamecube emulator with sound and debugging features that works so that we can analyze the format from there. Who knows, we even might be able to make 3sf rips...
thakis programmed some tools for GC files a whole while ago, among them an ARC archive dumper. If your ripper has a different purpose I apologise for the useless information. :-)
3sf? What's that an acronym for?

Sorry for the static.
Decoding is done thus:
outbin=*(long*)inbin - 128;
idx = (outbin)&0xf;
outbin=((outbin-16)+afccoef[idx][1]);
outbin=(outbin << 8)^0x8000; // convert to 16-bit signed pcm
Samples should be decoded at 18000 Hz
This uses some code from the AFC decoder, and I must admit that it works quite nicely, though not accurately.
...
What, you're still here?
Fine, take these wavs and leave me alone!
Wavs from Super Mario Sunshine and Luigi's Mansion
This is on megaupload as the ftp uploads here are slow and I am collapsing from drowsiness atm, so get it while its hot.
Decoding is now done thus:
for (int i=0;i<2;i++) {
outbin=*(long*)inbin + 128;
idx = (outbin)&0xf;
delta = 1<<(((outbin)>>4)&0xf); // currently unused.
outbin=outbin^afccoef[idx][i];
outbin=(outbin << 8)^0x8000;
// output the audio here...
}
and the samplerate is 36000 Hz.
The way decoding is done is pretty much the same as before, but at least it's easier to hear now.
I'm also doing analysis on the BMS format as well. Setting up the instruments seems to be done thus
SET_INSTRUMENT(long instrument,long offset)
C1 0000 00E2
In theory, to get to the function that handles music, we could xref DVD-related functions until we land at the jaudio sequence subroutines.
