GfK: be realistic. If I'd take out some crowd-noise from a random sports event, EQ it, mix it with inversed versions, pitch-shift it a bit, freq-shift it a bit, swap offsets, then there's no one in this universe who'll ever find out. A lawsuit, started by whom? Or do you really think there's a sports director who plays siread's game with that completely tweaked crowdnoise, and thinks: 'damn! that sounds like my crowd!' ? :P
