Digital audio watermarking method with MP3 tolerance using smearing-desmearing transformation

摘要

We propose a new digital audio watermarking method with MP3 tolerance. This method is realized by using smearing-desmearing transformation, optimization of signature impulse sequence, and amplitude shift keying of the smeared signature impulse sequence modacation. By a computer experiment it is shown that the proposed method has an excellent effect in audio watermaking to MP3.
