Try the VMod Pro voice changer

This is the VMod Pro firmware compiled to run in a browser. The menus, effects and pitch engine are the ones on the hardware. It runs locally on your own machine, with nothing to install.

This is the real VMod Pro firmware running in your browser. Turn the knobs, browse the menus, and hear every effect, including the PSOLA pitch shifter.

Runs in your browser. Nothing is uploaded and nothing installs.

What the demo does

Pitch shifting
Shift a voice up or down in semitones, with formant correction on or off so it does not sound like a chipmunk. It is the same PSOLA shifter the hardware runs.
All 11 effects
Pitch Shift, Overdrive, Bitcrush, Ring Mod, Chorus, Phaser, Flanger, Delay, Compressor, Reverb and a 4-band EQ. Run them together, re-order the chain, and set a wet/dry mix per effect.
The full interface
Every menu, parameter page, the mixer, the visualizer and the LED ring behave as they do on the unit, so the demo doubles as a look at the manual before you buy.

Online voice changer FAQ

Do I need an account or a download?

Neither. The firmware runs in the page, on your own machine, so nothing you do is uploaded anywhere.

Can I hear the effects on my own voice?

Yes. Record captures a short clip from your microphone, and Load audio takes a file from your device. Either one plays through the effects in place of the built-in clips. Both stay on your machine, are never uploaded, and are gone when you close the page. The demo only asks for microphone permission if you press Record.

Does the online voice changer work on a phone?

It runs on current mobile browsers, and the encoder and knobs respond to touch. A desktop browser gives smoother audio and easier control.

Is the demo the same as the real VMod Pro?

It is the same firmware source, compiled for the browser instead of the STM32H7. The menus, effects, parameter ranges, presets and pitch engine are identical. A browser cannot reproduce the feel of the encoder detents or the latency of dedicated hardware.

What can I use a voice changer for?

Cosplay and costume helmets, streaming and video production, theatre, haunted attractions, airsoft and milsim radio voices, podcasting, and vocal work in music. Anywhere the voice has to change live rather than in post.
