How to make frequency modulation
Posted: Tue Jun 09, 2015 12:57 pm
Hi all there! I want to make frequency modulation without a FM module for experiments and for possibility to use any sound as a carrier, not only sine. I am trying to use this approach:
The Sound2Ctl controls pitch of the top Pitch Shifter Module.
My questions are:
1. Can this approach works at all? I don't exactly know sunvox specific of sound processing in the top Pitch Shifter, it seems the module needs very quick responsiveness and large intput buffer. (Visualization is not perfect on the screenshot…)
2. If it can, how should I setup the Sound2Ctl and bottom PitchShiffter? Obviously sampling rate must be maximized. I have troubles with the Gain and Smooth parameters.
3. How can I calculate a frequency of the final modulator signal? For example, the bottom generator plays C4, Pitch=-4, Pitch scale=50%, so final frequency is approximatly 261.63 Hz / (4 * 0.5) = 130.815 Hz. Is it correct?
Thanks.
