It appears to be Gamecube DSP ADPCM. Here are the pairs of coefficients: FD D5 02 74 08 94 FB BC 05 E1 FF D7 0D D4 F9 93 02 7C 02 85 0B B9 FA E4 07 28 00 6A 0E 6F F9 73 I'm not sure how to play it with that information, but I'm sure someone with more knowledge can help you out.
It's (of course) the theme/opening from the original anime TV show, and it's absolutely brilliant.
This must have been directly from the master audio tapes or something, even the DVD remasters of the show sound like shit compared to the Gamecube audio.
Even music from games released today don't come close to the sound quality the music from this game has.
The fact that the norm these days is compressed ogg, ADPCM or CRI ADX, while nearly 16 years ago they were putting master-quality audio in games just shows how the standards have dropped.
The rest of the files are standard 44.1KHz 4-bit ADPCM, but the 24-bit audiophile-grade track at the end of the pac file blew me away, and I needed to share it!
Could you rip the musics man? I'm trying at least for one month to rip it and could not do it. You'll do a great favor for me if you can rip the music from those .pac files.
And yes, they are used in the games. I can only open them in Awave Studio but they sound terribly in that program.
I'm waiting for the good news. Really excited!!! :D
