Abstract: This paper analyzes the energy and reliability of audio watermarking algorithm based on psychoacoustic model. It presents the method of detection threshold of watermark correlation detection, and describes the connection of the watermark energy, detection threshold, and SNR with the detection error. The experimental results show that watermarking detection error decreases with the increase of watermarking energy and SNR .

Key words: audio watermarking, psychoacoustic model, energy, correlation detection, reliability
