Audio watermarking is a technique providing a promising solution to copyrights protection for digital audio and multimedia products. Using this technique, hidden information called watermark containing copyrights information is imperceptibly embedded into the audio track of a host media. This watermark may be extracted later on from a suspected media to verify the authenticity. To function as an effective tool to enforce ownership rights, the audio watermarking scheme must satisfy the imperceptibility, robustness, security, data payload, and computational complexity requirements. Throughout this book we will be illustrating in a practical way the commonly used and novel approaches of audio watermarking for copyrights protection. We will also introduce our recently developed methods for objectively predicting the perceptual quality of the watermarked audio signals.
