Audio Bandwidth Extension: Application of Psychoacoustics, Signal Processing and Loudspeaker Design

Erik Larsen, Ronald M. Aarts0470858648, 9780470858646, 9780470858653

Larsen (speech and hearing bioscience and technology, Massachusetts Institute of Technology) and Aarts, a researcher in the private sector in The Netherlands, examine applications of bandwidth extension (BWE) to music and speech, placing special emphasis on signal processing techniques. Covering theory, applications, and algorithms, they review important concepts in psychoacoustics, signal processing, and loudspeaker theory, and develop the theory and implementation of BWE applied to low-frequency sound reproduction, perceptually coded audio, speech, and noise abatement. An overview of a BWE patent is included. The book will be of interest to engineers, researchers, and postgraduate students in audio, signal processing, and speech.
