Invisible Acoustic Watermarking
VCaaS permanently embeds an inaudible, cryptographic signature into every generated voice clone. This ensures that deepfakes can always be mathematically proven as synthetic.
19kHz Sine Carrier
We use an ultra-high frequency band (19kHz) that is imperceptible to human hearing but perfectly preserved by standard microphones and compression algorithms like MP3.
Cryptographic Payload
The embedded signal isn't just a tone. It encodes a 16-character hexadecimal payload mathematically signed using a secure HMAC key, making it impossible to forge.
Try it yourself
1. Use the Inject tab to clone a voice. The system will automatically embed the 19kHz signature.
2. Download the resulting audio file.
3. Use the Extract tab to re-upload it. Watch as the cryptographic payload is instantly recovered from the raw audio waveform.
