About

Ring Modulator

This app creates unique metallic and bell-like timbres by multiplying two audio signals. It offers three modes for versatile sound design, from internal oscillators to sidechaining external audio.

Highlights
  • Ring modulation effect
  • Dual input capability
  • Three distinct modes (OSC+OSC, INPUT+OSC, INPUT+SIDECHAIN)
  • Mono and stereo input support
  • Adjustable carrier and modulator frequencies
  • Mix and output gain controls

Ring modulation multiplies two signals together sample by sample. The result contains the sum and difference of their frequencies, the sidebands, while the original carrier and modulator tones are suppressed. This produces the metallic, bell-like, and clangorous inharmonic timbres associated with classic ring modulators, from robot voices to detuned percussion. Signal path: the carrier is multiplied by the modulator to form the wet signal, Mix blends that against the dry carrier, and Output applies a final makeup gain. Ring Modulator is usable in three modes and can take either mono or stereo inputs. The host app must support mixing to bus inputs or sidechaining in order to use Ring Modulator with dual input. Outputs mono signal. OSC + OSC Both carrier and modulator are internal sine oscillators, set by Car Freq and Mod Freq. Produces classic two-tone ring modulation with no input required, good for bell tones and metallic drones. INPUT + OSC The carrier is your track's audio and the modulator is the internal sine at Mod Freq. This is the standard ring-mod effect: it turns voices and instruments metallic or robotic and adds inharmonic sidebands. This is the default mode. INPUT + SIDECHAIN The carrier is the main input and the modulator is a second, independent input routed into the plugin's sidechain bus. Use it to ring-modulate one track by another, for example a vocal shaped by a drum loop or synth pad. This requires a host that supports sidechain routing; if nothing is routed to the sidechain, the input passes through dry. Car Freq and Mod Freq do not apply in this mode.
