A WAV Format Audio Digital Watermarking Algorithm Based on HAS

摘要

Based on auditory masking effect, WAV format audio signal is programmed to embed a DWT (discrete wavelet transform) efficient digital watermarking algorithm of WAV format VF watermarking, conducting the embedding of the watermarking, extraction and anti-piracy properties research by using Matlab7.0 programming. Simulation results show that VF watermarking, embedded in the algorithm has good imperceptibility, robustness and strong resistance of usurping the ability of the copyright.
