Why VoiceOffer

Natural sound

To the human ear, the audio stays the same. Protection acts on frequency ranges the brain ignores.

Private by default

Your files stay isolated in your account. Only you have access — not anyone else, not even us.

Batch upload

Upload up to 250MB at once. The queue processes a few at a time to avoid overloading the server.

Trusted by players

For those who depend on high-performing ads.

How it works

1. Upload your audio

Drag one or multiple audio or video files. Supports MP3, WAV, M4A, MP4 and MOV.

2. Choose the strength

Adjust the slider to make protection lighter or more aggressive. Balanced default.

3. Download protected

Each file comes with a download link when ready. For batches, download everything in a single .zip.
