【Abstract】 To describe the digital audio watermarkings based on wavelet transform. Because of its excellent local time-frequence analysis and multi-analysis, wavelet transform has been used well in the field of the copyright protection of the music. The present algorithm of audio watermark technique on wavelet transform are reviewed with related concepts and discussed in detail. Furthermore, the development trends and perspective of digital audio watermarking technique on wavelet transform are predicted.更多还原
