In ring modulation patches, I have noticed that some people use the windowing function to make the signal from modulator all positive instead of orginal alternation of positive and negative values. I did some experiments with both and found that the resulted sound with bipolar modulator "vibrates" twice faster as the one with unipolar modulator but don't know why.
Could any one let me know the purpose of making unipolar modulator in ring modulation patches instead of bipolar ?
I also would like to know what happens with the carrier signal when the signal value of modulator goes below 0. Please explain.
Thank you so much.
