High capacity robust audio watermarking scheme based on DWT transform

This paper proposed an audio digital watermarking algorithm based on the Discrete wavelet transform (DWT) by combining with human auditory model and using the masking effect of human ears. This algorithm is realized to embed a binary image watermark into the audio signal and improved the imperceptibility of watermarks. Experimental results show that this algorithm has a better robustness against common signal processing such as noise, filtering, resampling and lossy compression.
