Crazy Taxi 3 .BIN audio containers

[McCunyao]

Greetings. I've found a rare dub of this game for the PC version and I'd like to pop open the format. The encoding seems to be ADPCM, could be XMA or something like that. The files inside are headerless, and there's a pointer table at the end of the file. That's as much as I can figure out.
