well the spectrogram only updates 44100/512 times a second, and looks cool and generates 5% cpu load on winXP...so why not? i'd hve to have enforced throttling ((isnt that pretty antithetical)). but it seems there may be some throttling in place? for example loading wavs into my BLT wav editor takes FOREVER on windows...but on linux its quite fast...
