摘要：Audio watermarking is a technique, which can be used to embed information into the digital representation of audio signals. The main challenge is to hide data representing some information without compromising the quality of the watermarked track and at the same time ensure that the embedded watermark is robust against removal attacks. Especially providing perfect audio quality combined with high robustness against a wide variety of attacks is not adequately addressed and evaluated in current watermarking systems. In this paper, we present a new phase modulation audio watermarking technique, which among other features provides evidence for high audio quality. PSK modulation has been proposed as an effective approach to watermarking.
