Ring Modulation + Phase Modulation

Oh I also suggest using a sine wave as the secondary input because it sounds cooler

But if one is not playing sound then the other one does not play because they both have to play at the same time

You need the main input and the second one and you put them both in. Then you adjust the volume boost on the ring modulator, you can look at youtube videos

tomorrow

I could show you
