Voice changer FAQ
How do I change my voice online for free?
Open the voice changer, record a clip or upload an audio file, tap one of the 12 effects and press Download WAV. There is no account, no payment and no watermark.
Can I download the changed audio?
Yes. Every result can be saved as an uncompressed WAV file, ready for video editors, games, podcasts or messaging apps.
Which audio formats can I upload?
Anything your browser can decode, which normally covers MP3, WAV, M4A, AAC, OGG and WebM recordings.
Is my recording private?
Completely. The microphone stream and all effect processing stay inside your browser using the Web Audio API — no file is ever sent to a server.
Does the voice changer work in real time on calls?
It changes recorded clips rather than a live call. Record, transform and download, then play the file back in the app where you need it.
Why can't the site hear my microphone?
The browser needs microphone permission. Check the padlock icon in the address bar and allow access, or upload an existing recording instead.
Is there a length limit?
There is no hard limit, but very long clips use more memory because processing happens on your device. A few minutes at a time works smoothly.
Can I use the audio commercially?
Yes. You own your recording and the transformed version, so you can use it in monetised videos, games and client work.
