This book is in part the outcome of many years of research and teaching at Arizona State University. We opted to include exercises and computer problems and hence enable instructors to either use the content in existing DSP and multimedia courses, or to promote the creation of new courses with focus in audio and speech processing and coding. The book has twelve chapters and each chapter contains problems, proofs, and computer exercises. Chapter 1 introduces the readers to the field of audio signal processing and coding. In Chapter 2, we review the basic signal processing theory and emphasize concepts relevant to audio coding. Chapter 3 describes waveform quantization and entropy coding schemes. Chapter 4 covers linear predictive coding and its utility in speech and audio coding. Chapter 5 covers psychoacoustics and Chapter 6 explores filter bank design. Chapter 7 describes transform coding methodologies. Subband and sinusoidal coding algorithms are addressed in Chapters 8 and 9, respectively. Chapter 10 reviews several audio coding standards including the ISO/IEC MPEG family, the cinematic Sony SDDS, the Dolby AC-3, and the DTS-coherent acoustics (DTS-CA). Chapter 11 focuses on lossless audio coding and digital audio watermarking techniques. Chapter 12 provides information on subjective quality measures.
