Abstract :
How to perform the audio watermarking algorithm in the DSP chip, and how to load and deal with real-time audio watermarking are two points that this paper focuses on. A real-time processing for fast audio watermarking algorithm is mentioned in this paper. The algorithm is available for the implementation in DSK5402. Experimental data shows the algorithm has good robustness and transparency in audio watermark processing.
