Fisher Audio (Sid Fisher's Proffesional Recordings for SL)just my previous experience with the Amiga sampling software coming out from 1994)
Now, and before, specialising in low lag seamless loops of sounds that dont need a scripted orb, atmo-sphere, or any heavily scripted object with 30 meg of sounds(200 seconds of sounds), so.... just get a few of these seamless loops and a randon scripted multi-sound emitter and that is all you will need. the loops have a 10m radius, and the MSE's go 100m, its amazing what effects one can create.
