Audio watermarking
A deliberate, usually inaudible marker embedded by the generator at synthesis time.
Some platforms embed watermarks so their own output can be recognised later. When a watermark is present and the reading key is available, this is far more reliable than any statistical inference — it is a designed signal rather than an inferred one.
The catch is that watermarks are proprietary, detectable only by the party that issued them, and often survive poorly through re-encoding, pitch shifting or re-recording. From an independent tool's position they are unreadable.
How this tool uses it
Not read. This tool performs acoustic analysis only and makes no watermark claims in either direction.
What else produces the same reading
- Absence of a detectable watermark says nothing, since you cannot read most of them anyway.
- Re-encoding and re-recording can destroy watermarks.
