Forensic audio watermarking
Audio watermarking for music you need to trace.
Listening Copy can embed a different inaudible identifier in every recipient's listening copy. If that audio later appears where it should not, you can scan it and identify which delivered copy matched.
What a recipient watermark does
A normal private link controls access to one URL. A recipient watermark travels inside the audio itself. Listening Copy connects that embedded identifier to the recipient label you supplied, giving you a traceable delivery record without putting the recipient's name or email directly into the audio payload.
How it works
- Create a protected send.Choose a track or playlist and identify the intended recipient.
- Listening Copy prepares a unique copy.A keyed, recipient-specific identifier is embedded before delivery.
- Trace a suspect file.Upload the file to Trace; a valid match points back to the delivery record.
What it does not promise
A watermark is not DRM and cannot prevent someone from recording or copying audio. It is a best-effort tracing signal, not proof of identity or legal liability. Heavy processing—including time stretching, pitch shifting, re-recording or severe re-encoding—can damage or remove it. A trace result should be investigated alongside your delivery records and other evidence.
Watermarked output is a high-quality MP3 listening copy, not a replacement for a WAV or FLAC master. Use ordinary lossless delivery when the recipient needs production-ready files.
