Dankira audio files, decoding help by OtogeHelp at 6:57 AM EST on December 9, 2020

I tried to figure this out on my own but after spending about three days on it I decided to finally ask for help. Sorry for the troubles.

I'm trying to extract the soundtrack from the Konami mobile game Dankira: Boys Be Dancing. It's an offline game that clocks in at about 3.2GB, I'm afraid. Its id is jp.konami.dankira

The audio files are encoded and just end up playing shrill buzzing in vgmstream. I've been pouring over a hex editor trying to figure out the decode keys but I haven't been able to figure it out.

The audio files are in the file patch.20010.jp.konami.dankira.obb inside of the xapk. The OBB is extractable as a CPK.

If it's helpful, here's a sample acb/awb pair.

Thanks for any help that you can give. I'm very appreciative.

Sample plays fine for me. Try some non-ancient vgmstream:

Thanks. I feel a bit dumb right now, but you're right! Also I figured out what I was doing wrong.

For the record I was extracting HCA's from the AWB/ACB pairs and trying to play them that way because I typically preview them in Foobar, which doesn't do the AWB/ACB pairs and this is the method that worked for another game I've datamined. User error on my part for assuming it'd be the same instead of just trying the command line version of vgmstream. Sorry for the trouble!
