Many different watermarking schemes for a large variety of data types have been developed. However, creating a watermark for audio files that will work and be inaudible to the human ear is harder and more challenging due to the fact that the human auditory system is much more sensitive than the human visual system. In this book, an audio watermarking algorithm is proposed to embed copyright protection information into a digital audio wave file that was implemented in MATLAB. Extraction algorithm is also proposed to prove the author¿s rights of the watermarked audio signal. Furthermore, this book includes a clear definition of the watermarking technology and what differentiates it from other systems, the properties that the watermark must satisfy, types of watermarks, their applications, possible distortions and attacks that might be encountered, watermarking in spatial and transform domains, some audio watermarking algorithms and the criteria used to perform evaluation for audio watermarking algorithms. Analysis and evaluation for the proposed algorithm are also presented. This book is directed towards researchers and academics who are interested in audio watermarking.
