Audio watermark

Audio watermarking is a way of embedding a kind of 'signature' into a piece of audio, like music or a voice recording. This 'signature' is like a secret code that can't be heard but can be used to prove that the audio belongs to someone. The audio watermark is like a digital fingerprint, so if someone tries to copy the audio and claim it as their own, the audio watermark can help show that it is the original.
