Since compact discs first began to supplant vinyl records as the delivery mechanism for audio, the demand for high-quality digital audio at low bit rates has risen exponentially. Dr. Ted Painter and Professor Andreas Spanias have provided a comprehensive study of the most significant developments in audio coding in “Perceptual Coding of Digital Audio.” The paper, with its discussions of perceptual coding building blocks, research literature and standards, serves as a tutorial for the novice, as a reference for the experienced practitioner and as a bibliographic roadmap for the expert researcher. Containing more than 400 references, it has been widely cited by researchers and practitioners in fields ranging from software development to human auditory perception.
Andreas Spanias is a professor in the Electrical Engineering Department at Arizona State University, where he conducts research in adaptive signal processing and speech processing. An IEEE Senior Member, he has served in numerous capacities including as associate editor of the IEEE Transactions of Signal Processing, is currently associate editor of the IEEE Signal Processing Letters. He is a member of the IEEE Signal Processing Executive Committee and the Society's Board of Governors.
