About Voice Changer

The Voice Changer turns your voice into a chipmunk, a movie-trailer baritone, a robot, an alien and more. Record straight from your microphone or drop in an audio file you already have, pick an effect, and hear the result immediately.

Eight presets are included (Original, Chipmunk, Deep, Robot, Echo, Telephone, Alien and Cave) built from pitch and speed shifting, band filters, ring modulation, delay and reverb, so each one has a genuinely different character instead of one dial turned further.

Everything runs in your browser with the Web Audio API: your audio is decoded, processed and exported on your own device, and the take you keep downloads as a 16-bit WAV file. The tool is completely free, needs no account and charges no credits.

How to use Voice Changer

  1. Click “Record microphone” and allow microphone access, or upload, or drag an audio file anywhere on the page.
  2. Press Stop when you are done; your clip appears in a player straight away.
  3. Choose a preset: Chipmunk, Deep, Robot, Echo, Telephone, Alien or Cave.
  4. Hit Preview to hear the effect, and switch presets freely until one fits.
  5. Click “Download WAV” to save the processed take to your device.

Frequently asked questions

Yes, completely. Recording, previewing every preset and downloading the result are all free, no credits, no account and no limit on how many takes you make.

No. Microphone capture, decoding, effect rendering and the WAV export all happen in your browser with the Web Audio API. Nothing is sent to or stored on our servers, and closing the tab removes every trace of the recording.

Yes. Use “Upload audio” or drag the file anywhere on the page: any format your browser can decode works, including MP3, WAV, M4A, OGG and WebM. The processed take is always saved as a WAV file.

Eight: Original (untouched), Chipmunk, Deep, Robot with a metallic ring-modulated tone, Echo with canyon-style repeats, Telephone for a thin crunchy phone line, Alien for a wobbly warble, and Cave for a huge reverberant space.

The Chipmunk and Deep presets shift pitch by changing the playback rate, so pitch and speed move together: the classic cartoon effect. The Robot, Echo, Telephone, Alien and Cave presets keep the original speed and shape the sound with filters, modulation and delay instead.
