Abstract :
Based on wavelet decomposition and relative energy compare, a sonic audio watermarking algorithm was proposed in which the wavelet coefficients were chosen for relative energy calculation and compare, and the embedded watermark had large capacity. Experimental results indicate that the proposed algorithm can be applied to cable-transmission situation with good hidden effect and strong robustness, and bit error is from 0.01% to 0.68%.
