Abstract:
A method to watermark an audio signal includes inserting a first symbol in a spectral well, the spectral well corresponding to at least one of a second spectral portion when amplitude of a first spectral portion and amplitude of a third spectral portion exceed amplitude of the second spectral portion, or the second temporal portion when amplitude of a first temporal portion and amplitude of a third temporal portion exceed amplitude of the second temporal portion.
