More about this voice

What water does to a voice

Water and walls let low sounds through and swallow high ones. The preset copies that with a steep cut at 650 Hz, which keeps the rhythm of your speech but blurs the consonants. A chorus moving 1.2 times a second makes the sound swell and sway, and a short, heavily damped reverb gives it a closed-in feel.

Deeper or calmer

Treble cut at 400 Hz: deeper under the surface. Words are hard to make out, which is the point for a gag or a dream scene.
Wobble at 0.5 times a second: a slower, lazier swell, more like drifting than bubbling.
For a voice that's still understood, leave the preset as it ships and speak slowly and clearly.

Free underwater voice changer FAQ

Can people understand me?

Mostly, if you speak slowly. The high frequencies that carry consonants are cut, so fast speech blurs.

Does it add bubble sounds?

No. It changes your voice only. Play a bubbles sound from the Facecam soundboard on top if you want them.

Is it free?

Yes, it runs on your computer in Chrome, with no account.
