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