Abstract. This paper presents a novel method of an audio signal digital watermarking by an audio signal. The method is based on the conformal algebra transformations of a unit disk. The paper examines the results of modeling method in time domain and estimates computational complexity. Encouraging results have been presented showing digital watermark embedding and extraction with negligibly small distortions.
