Bandwidth extension (BWE) refers to various methods that increase
either the perceived or real frequency spectrum (bandwidth) of
audio signals. Such frequency extension is desirable if at some
point the frequency content of the audio signal has been reduced,
as can happen for example during recording, transmission or
reproduction.
This volume, significant in dealing exclusively with BWE,
discusses applications to music and speech and places particular
emphasis on signal processing techniques.
* Presents an all-encompassing approach to BWE by covering
theory, applications and algorithms
* Reviews important concepts in psychoacoustics, signal
processing and loudspeaker theory
* Develops the theory and implementation of BWE applied to
low-frequency sound reproduction, perceptually coded audio, speech
and noise abatement
* Includes a BWE patent overview
Audio Bandwidth Extension pulls together recent developments
in to a single volume and presents a coherent framework to the
reader. Such an approach will have instant appeal to engineers,
specialists, researchers and postgraduate students in the fields of
audio, signal processing and speech.
