yeah, got the point. however with hi-gain input, there's only a few samples between the lower and upper clipping threshold, so i'm afraid it will not guarantee bandlimited operation. this is largely based on intuition though. probably the 'how to anti-alias a hard clipper' topic is more of a music-dsp question. >> for building a decent 'virtual amp', i imagine some combination >> of Steve's excellent valve and valve_rect for a good, smooth >> and warm lowish-gain tone, a bit of tunable eq and this kind of >> hard-clipping for hi-gain, harsh distortion topped off with a >> cabinet response will just about do it for me. > >Yup, thats sounds like its going to rule. Its not really fair to call the >valve mine though, I just copied it from someones thesis! you made the valve_rect though which helps a lot to get a good attack for lo-gain inputs. (and besides, do you seriously want to deny that you wrote these plugins? ;) any hints for good pre- and post-eq? i'm planning to use one lo-, 1 to n band- and one hi-pass. i'll probably still do the integer-period saw wave recordings unless you say you don't think we need those. tim
