Abstract :
A real-time audio watermarking scheme is presented. The strength of audio signal modifications is limited by the necessity to produce an output signal that is perceptually equal to the original signal. The proposed scheme uses a blind detection approach. To embed the watermark a spread spectrum algorithm is used in the modulated complex lapped transform (MCLT) domain. Here the watermark is generated using a private key and modeling according to the human auditory system. Comparison of several whitening methods in the receptor side is carried out. The embedded watermark is robust to common attacks such like, D/A A/D conversion, filtering, noise addition and high quality MPEG audio coding
