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, a real-time granular pitch shifter (two crossfaded modulated delay lines), a ring modulator for the robot effect, a waveshaper (distortion), a delay node with feedback, and a convolver reverb with a generated impulse response. Pitch shifting is genuine (the chipmunk and deep-voice presets actually re-pitch your voice), all done locally with stock Web Audio nodes — no external library or upload.
