What is a voice changer?
A voice changer takes a recording of your voice and transforms it into a different character — higher (chipmunk, helium), lower (deep, demon), child-like (baby), or massive (giant). It works by combining pitch shift and small tempo changes.
How do the presets work?
Each preset is a combination of pitch shift in semitones and a small tempo adjustment. Chipmunk = +7 semitones, faster. Helium = +12. Baby = +9, slightly slower. Deep = −6. Demon = −12, slower. Giant = −9, slower.
Will it sound real?
The presets are stylized — perfect for memes, pranks, character voiceover, gaming videos, and animation. They are not designed to be undetectable disguise. For serious anonymization, combine the deep preset with the de-esser and EQ in the Notevibes Audio Editor.
Can I tune the pitch and tempo myself?
Not on this preset-only page. Use the pitch changer for fine pitch control, the tempo changer for time-stretch, or the Audio Editor to combine both with custom values.
Is the voice changer free?
Yes. Completely free with no sign-up, no watermark, and no limits. Max file size is 200 MB.
Is my audio file uploaded to a server?
No. The voice changer runs entirely in your browser. Your file never leaves your device.
What audio formats are supported?
MP3, WAV, M4A, FLAC, OGG, and AAC. Anything your browser can decode will load. Output is exported as a 192 kbps MP3.
Does it work on mobile?
Yes. It runs on Chrome, Firefox, Safari, and Edge on both desktop and mobile.

Yes. The AI audiobook generator turns your EPUB, Kindle, or PDF into a narrated audiobook with character detection, 550+ voices, and ACX-compliant volume normalization built in.
