Extracting/Converting Gamecube .SAMP banks?

[SuperMario123311]

Hey, Sorry to brag but I'm having trouble finding out what the hell to do with these. I imported the raw data into Audacity and through the static I can KIND OF make out a few voice clips from the soundbank for Bomberman Jetters. Apparently Wario World uses the same format for it's sounds but I don't know of any real program that could extract these. Help would be greatly appreciated.

Just looking for more info if possible?
