| This paper constitutes a proposal of a method of spectral shaping of the watermark signal without adjusting the interception point based directly on psychoacoustics of the human auditory system and the proposed calculation formula. The proposed calculation formula enables correction of watermark signal both as regards its spectrum shape and adjustment of watermark signal to the host's JND. |
