The ModulationNode collects audio data from all of its inputs and applies either amplitude or ring modulation to the audio before passing it along to its outputs.
Common Uses
- Using amplitude modulation to regularly vary the volume of a sound
- Using ring modulation to create sound effects or synthesizers
Using the ModulationNode
Amplitude modulation will oscillate the volume of the audio at a rate set by the Frequency property. The volume changes from 0 to 1.0. If the user does not want the volume to go to silence, setting the WetPercent to values below 100 will reduce the strength of the modulation.
Ring modulation will directly alter the frequencies of the sound, with stronger effects as the Frequency value gets larger.
