Ring Modulator Patch

Use the Ring Modulator patch to create an oscillating sound effect with varying pitches. Modulation is often used as an experimental audio effect and is found in many synthesizers.



Connect the audio source that you want to alter, for example an audio clip, microphone or other audio source.


The frequency of the modulator sin wave in Hz. Accepts values from 20 to 10,0000.


Blends source audio with affected audio, measured as a percentage. A value of 0 will pass only the source signal, while a value of 100 will pass only affected signal. Adding some of the source signal with the affected signal can enhance the overall effect.


Removes the sound effect from the audio source.



Connect to a speaker, an audio effect or another patch that has an audio input.

Example - oscillating, alien sound

In this example, we’ll edit the values in the Distortion patch to add a slightly fuzzy effect to sound detected by the Microphone.

This is what the audio effect sounds like.

In the Patch Editor, a patch representing the Microphone scene object is connected to the Audio port in the Modulator patch. The output of the Modulator patch is then connected to the input of a patch representing the Audio property of a speaker.

To create the fuzzy sound, we set:

  • Frequency to 100. Adjusting the Frequency creates interesting layers and overtones that make the audio going into the modulator come out sounding strange.
  • Mix to 100. Mix is used to blend the sound that comes out of the distortion effect with the clean, unaffected sound. Setting this value to 100% only sends out audio affected by the modulator.
  • Bypass to OFF. Bypass turns the distortion effect on or off. When the box is unchecked, the distortion effect is turned on.
