Audio pieces of different genres, sampled at 44.1 kHz, were tested against the watermarking system. It was found that both the host signal and the attacks act as noise in watermark extraction, the host signals affecting the extraction more severely. It was also found that there is an improvement of about 3dB at bit error rate (BER) of 10<sup>-5</sup> in the modified system.}, number={3}, journal={Canadian Acoustics}, author={Zhang, Libo and Krishnan, Sridhar and Ding, Heping}, year={2004}, month={Sep.}, pages={142–143} }
