Summary :

A novel audio watermarking based on wavelet modulation is presented. The watermark signals are constructed by M-band wavelet modulation that can increase redundancy to improve the detection performance. In order to maximize the watermarking strength within the perceptual constraints, the watermark signals synthesized from different subbands are separately masked using a frequency auditory model. CDMA technique is implemented to achieve watermarking capacity. Experimental results show that this method is very robust.
