Audio Watermarking and Applications
http://www.metois.com/Docs/audiowatermark.pdf
Watermarking Audio Content Process Unlike sub-codes, encryption or audio compression, an audio watermark should not rely on any specific format. In order to travel along with the content it protects, the watermark must be carried by the content itself. Embedding an audio watermark is an active modification of the audio waveform.
Audio Watermarking: A Critical Review - IJSER
https://www.ijser.org/researchpaper/Audio-Watermarking-A-critical-review.pdf
A survey of audio watermarking techniques noted that for sensitivity of human ear the design of good audio watermarking schemes are not easy to design and that current watermarking techniques are far from being perfect (Hyoung, 2004). Table 1 below shows the characteristics of the algorithm considered.
