In this article, a BCH code-based audio watermarking approach performed in the cepstrum domain is proposed. The technique takes advantage of the attack-invariant feature of the cepstrum domain and the error-correction capability of BCH code to increase the robustness of audio watermarking. In addition, the watermarked audio has very high perceptual quality. A blind watermark detection technique is developed to identify the embedded watermark under various types of attacks. Experiment results demonstrate that the proposed technique outperforms the existing audio watermarking techniques against most of the asynchronous attacks.

Keywords: audio watermarking, cepstrum domain, permutation, error correction coding, BCH code
