DIGITAL AUDIO WATERMARKING: SURVEY

Digital audio watermarking is a technique for embedding additional data along with audio signal. Embedded data is used for copyright owner identification. A number of audio watermarking techniques are proposed. These techniques exploit different ways in order to embed a robust watermark and to maintain the original audio signal fidelity. This paper makes a tutorial in general digital watermarking principles and focus on describing digital audio watermarking techniques. These techniques are classified according to the domain where the watermark is embedded.
