Free Online Voice Changer

An online voice changer alters how a voice sounds without installing software. This one changes pitch: it makes a recording higher or lower while correcting the speed so the length stays about the same. It works on files you choose, not on a live microphone.

1. Click Choose files and select your recording. 2. Enter a Pitch multiplier, such as 0.8 for deeper or 1.25 for higher. 3. Click Process audio. 4. Listen to the MP3 and click Download.

Only pitch shifting. There are no preset voices such as robot, alien or celebrity, and no AI voice cloning. You can still get a range of styles by choosing different multipliers between 0.5 and 2.

No. FFmpeg processes the file inside your browser, so your voice stays on your device. Only the FFmpeg engine is downloaded once from a public CDN and then cached.

Yes. It’s free, adds no sound tag and has no daily limit. Each file can be up to 100 MB and 10 minutes long, and you can try as many multipliers on the same file as you like.

Not noticeably. The tool resamples the audio to move the pitch, then applies a tempo correction that brings the duration back to the original. Large shifts can still add a slightly grainy texture.

An MP3 at 192 kbps, 44.1 kHz, stereo, named pitch-audio.mp3. If you started from a video, only the changed audio is exported, so put it back on the video in an editor.

No. It processes recorded files only. Record your lines with the online voice recorder, change the pitch here, then share or use the finished file.

That’s what a large multiplier does. Pitch shifting also moves the resonances that give a voice its character, so high values sound cartoonish and low values sound monstrous. Stay between 0.8 and 1.25 for a more natural change.

Yes, in current mobile browsers such as Safari on iPhone and Chrome on Android. Short clips process quickly on most phones, while files close to 10 minutes are faster on a computer.
