What is an audio watermark?

An audio watermark is a hidden or audible marker embedded in audio to identify the creator and protect copyright.

What is an inaudible watermark?

An inaudible watermark (steganographic) is embedded below the hearing threshold — listeners cannot hear it but it can be detected by software.

Can watermarks be removed?

Audible watermarks are difficult to remove cleanly. Inaudible watermarks can theoretically be stripped by heavy processing.

Does watermarking degrade audio quality?

Audible watermarks slightly affect the audio. Inaudible watermarks have negligible impact on perceived quality.
