This is getting interesting. I'm sorry, how did you do this with vd~? <br><br><div class="gmail_quote">2010/10/18 Mathieu Bouchard <span dir="ltr"><<a href="mailto:matju@artengine.ca">matju@artengine.ca</a>></span><br>

for a sinewave, a peak of ±1 millimètre at 1 kiloHertz travels like<br>
<br>
y = 0.001*sin(2000πt) mètres<br>
so<br>
dy/dt = 2π*cos(2000πt) mètres/seconde<br>
<br>
so, the peak speed is ±2π m/s while the speed of sound is roughly 343 m/s, thus the doppler effect would be ±1.83 %, creating a vibrato of ±32 cents, but this vibrato is so fast, that it actually sounds like something else, because it runs at the same frequency as the input signal.<br>
<br>
I tried it, and it sounds like related to waveshaping (although it's not). So maybe that's closer to what "fallen_devil" wants, because it has a quite richer sound than the usual [expr~ tanh($v1)].<br>
<br>
I did it using [vd~]. (I imagine that I will soon retry with a natural spline version of it...)<br>
