Bandwidth extension of signals may be defined as the deliberate process of expanding the frequency range (bandwidth) of a signal in which it contains an appreciable and useful content, and/or the frequency range in which its effects are such. Its significant advancement in recent years has led to the technology being adopted commercially in several areas including psychacoustic bass enhancement of small loudspeakers and the high frequency enhancement of perceptually coded audio. The increasing use of this technology in different areas creates a need for knowledge of the area. Written by an expert in the field, Signal Bandwidth Extension for Applications in Audio Signal Processing will consolidate the theories and applications surrounding signal bandwidth extension to help the reader develop a comprehensive knowledge of the area and its potential uses. An ideal reference for academics and professionals alike, it will be most suited to researchers and developers in audio engineering. However, it will also be suitable for those studying or working in areas such as signal processing, communications, audio and video engineering and coding theory

Click here to hear a music fragment which is recorded with a microphone at 1 m distance in front of a flat-TV using the build in mid- and high frequency loudspeakers, and the standard internal subwoofer which is about every 10 s alternated with the new driver, the latter has the deepest bass. Because the mapping frequency of the new driver is abt. 60 Hz, one needs headphones capable of reproducing these frequencies, to appriciate this demo, small PC loudspeakers are in general not capable to do so.
