VoiceOffer protects your audio while preserving a natural listening experience — making it harder for AI transcription and voice cloning systems to interpret.
To the human ear, the audio stays the same. Protection acts on frequency ranges the brain ignores.
Your files stay isolated in your account. Only you have access — not anyone else, not even us.
Upload up to 250MB at once. The queue processes a few at a time to avoid overloading the server.
For those who depend on high-performing ads.
Drag one or multiple audio or video files. Supports MP3, WAV, M4A, MP4 and MOV.
Adjust the slider to make protection lighter or more aggressive. Balanced default.
Each file comes with a download link when ready. For batches, download everything in a single .zip.
