"It might not be very 'artistic', but I suspect that a lot of this stuff could be done at the command line with scripts that take sample files, pitch shift them, concatenate and mix them, etc. Linux has lots of tools that could do things like that." hi mark, thanks for the kind and helpful words. if you have a sec, could you elaborate a little? i'm very comfortable at the commandline, but applying this sort of paradigm to computer audio is still unfamiliar for me. do you mean simply writing my own bash/python/whatever scripts and the like to process waveform audio? or are you thinking of some specific, smaller audio applications that are geared towards this kind of scripted approach, and could be strung/glued together using scripts? do you have an example(s) . . . ? if not, no worries, just thought i'd ask. cheers, hawkeye
