Microphone Access Required

Click below to allow microphone access and start the voice changer. Use headphones to avoid feedback.

Stream Voice Changer processes your microphone in real time using the browser's built-in Web Audio API — no audio is uploaded anywhere. The signal passes through a filter (cutoff + pitch detune), a waveshaper (distortion), a delay node with feedback, and a convolver reverb with a generated impulse response. Pitch shifting is simulated via filter detune (100 cents per semitone) and ring modulation for the robot effect — true pitch shifting requires an external library.
