A methodology of non-blind watermarking of the audio content is proposed. The outline of audio copyright problem and motivation for practical applications are discussed. The algorithmic theory pertaining watermarking techniques is briefly introduced. The system architecture together with employed workflows for embedding and extracting the watermarks are described. The implemented approach is described and obtained results are reported. The possible attacks on the embedded watermark are described and the procedure of simulating the attacks is explained. The research is focused on the influence of lossy compression on the embedded watermark degradation. The peak signal to noise ratio and bit error rate are analyzed and compared. Advantages and disadvantages of the proposed approach are discussed. Future work and some possible improvements to the introduced methodology are explained.
