Hi Edgar, These posts about the highpass filter & oscillations got me thinking... a 50ms burst of a 20Hz signal means exactly one cycle of the 20Hz tone. It's definitely audible with the following code: (mult (diff 1.0 (ramp 0.05)) ; 50ms ramp from 1 to 0 (osc (hz-to-step 20) 0.05)) ; 50ms of 20Hz tone (just as 10s of a 0.1hz tone is also one cycle of that tone, and so on... does that tone start at a specific point such as 0, 90, 180 or whatever degrees?) Which brings me to my next question: some time back Steven Jones helped me make a "Nyquist generate prompt", it has one line of text input (such as the above all on one line), but I'd like to have about 5 lines to enter code, like in the Nyquist prompt undr the effects menu. Do you know how to make this so? The file generate.ny is attached with this msg. Thanks David |
