I think he wants to know how to extract the sounds from the AKB files, Mystie 
If I can find the time I'll try to download and look through them. With luck they should be similarly simple to the FLB files.
EDIT: BGM_00.akb seems to contain OGG files, I'm seeing "OggS" and "Vorbis" around the place. More than I would expect though, it might be some weird variation or possibly even compressed? I hope not though. The other AKB files, either contain raw OGG/MP3/WAV data or some compressed stuff.
That was at a quick glance, maybe I can find out more when I'm not pressed for time.
