| Abstract: | We investigated embedding limitations with our proposed method of audio watermarking. This method was based on the concept of embedding inaudible watermarks into an original sound by controlling its phase characteristics in relation tocochlear delay. We improved the original method by designing a composite architecture for cochlear-delay filters. We evaluated the methods to investigate the embedding limitations by carrying out four objective experiments, i.e., with PEAQ, LSD, bit-detection, and robustness tests. The resultsindicated the embedding limitation with the composite architecture in the best case was 256 bps, while the embedding limitations with the parallel and cascade architectures were 192 and 128 bps, respectively. |
