Abstract

The energy of audio segment is adaptively judged by energy threshold based on traditional echo hiding algorithm so that echo signal is selectively added. Compared with the traditional algorithm by determining the amount of embedded data depending on the length of the audio signal, the new algorithm adaptively embed data according to the energy of audio segment so as to improve the problem of high error rate in decoding by traditional algorithm in the music signal echo hiding process. The simulation results by MATLAB show that the new algorithm increase the decoding accuracy rate by 10-20% compared to the traditional algorithm.
