Generally audio watermarking schemes based on patchwork algorithm show desirable performance in terms of watermark inaudibility and robustness. However an analysis about relationship between watermark payload, inaudibility and robustness have not been provided sufficiently in the literatures. Specially, to implement these schemes to the hardware, optimization of some parameters of the algorithm, which control watermark inaudibility and robustness, is indispensable. In this paper we analyze the Yeo’s audio watermarking scheme, one of representative patchwork based schemes, from watermark payload, inaudibility and robustness points of view. The watermark robustness is evaluated using Audio StirMark Benchmark Test.
