Microphone input: Allow browser microphone access to apply real-time voice effects. Works best in Chrome/Edge.
Effect presets: Normal (clean pass-through), Robot (pitch down 30% + distortion), Chipmunk (pitch up 80% for squeaky voice), Darth Vader (pitch down 50% + delay for deep voice), Radio (heavy distortion for megaphone effect), Concert Hall (delay + reverb for spacious sound).
VU Meter: Shows real-time input level with color zones - green (safe), yellow (loud), orange, red (clipping).
Waveform: Live scrolling waveform display of your voice signal.
Gain slider: Adjust input amplification from 0% to 200%. Higher values may cause distortion.
Noise gate: Cuts signal below threshold to reduce background noise. Increase if you hear static.
Record: Capture a short audio clip and play it back with current effects applied.
No microphone? Falls back to oscillator demo mode so you can still test all effects without a mic.
Keys: 1-6=Presets, R=Record, Space=Play recording, Up/Down=Gain.
