Ring Modulate Audio (vuo.audio.ringModulate)

Multiplies audio channels together.

Connect two or more audio sources to this node — a carrier channel and one or more modulator channels. Use a low frequency modulator (Make Audio Wave set below about 20 Hz) to produce a tremolo effect. Use a high frequency modulator (about 100 Hz to 5,000 Hz) to produce inharmonic, metallic sounds.

The name “ring modulation” comes from the analog circuit implementation of this effect, which uses 4 diodes connected in a ring. See this article for more information.
