摘要

Digital watermarking is a technique used to embed an extra piece of information into multimedia signals. Aiming at content-based audio retrieval applications, a robust audio watermarking scheme resist to low bits rates compression is proposed. The performance of proposed algorithm is analysis by common signal processing such as Mp3 compression, Real compression, filtering, amplitude compression, equalization, echo, resembling, etc. Experiment results show that proposed algorithm is insensitive to small local change, and therefore is suitable for distinguishing different audios.
