Best way to rip sounds from gamecube games

[Ecking Crew]

Are there any pro soundrippers out there who know how to do this? I've seen tons of GC rips on the net, and I want to be able to rip some myself from games I want to rip them from. I've ripped my fair share of GBA and SNES sounds, and have methods for doing each. Is there any good method for ripping gamecube sounds?
