A Digital Watermark for Stereo Audio Signals Using Variable Interchannel Delay in High Frequency Bands
2008
2008 International Conference on Intelligent Information Hiding and Multimedia Signal Processing
We propose a watermarking algorithm for stereo audio signals which embeds data using delay values of the high frequency channel signals. Since the stereo image perception of the human auditory system is known to be relatively insensitive to phase in high frequency regions, we replace the high frequency components with one middle channel, and embed data as delay between the channels. Blind detection of embedded data is possible using correlation between high frequency channels at the detector.
