I often use it to get the magnitude response plot of filters while changing params, so in that case it doesn't matter much if the period is truncated. I have a pulse function that I use to trigger grains in a granulator and, for that, I check the first diff of a phasor for float periods. I know that using the phasor is more expensive but I like that negative periods give you the anti-pulse function. :-) Ciao, Dario > All I can say is that if I send the output from "process = pulsef(P)" to > the > soundcard it does not sound nice, but I can certainly hear the difference > between P == 441.0 (100Hz with SR=44100) and P == 441.9 or even P == 441.5. > While ba.pulse() simply truncates 441.* to the integer == 441. > > Oleg. > >
