Digital Audio Watermarking by Magnitude Modification ofFrequency Components Using the CSPE Algorithm

摘要: In this paper we describe a process whereby the magnitude of either one or two frequency components signal is modified in order that it may be used to encode hidden message within such way as casual observer would have no noticing presence message. Previous work has filtering and addition achieve same goals. The current improves on by using recent super-resolution component-identification technique isolate modify, limiting impact quality signal.
