Acoustic Signal Processing for Telecommunication (The Springer International Series in...
Product Description The current revolution in electronic switching and transport technologies promises a dramatic increase in the intimacy and satisfaction that users will experience over imminent telecommunications networks. However, unless there is a corresponding improvement in the technologies of the acoustics of telecommunications, this promise will soon prove empty. The sense of presence that people feel when together in a room is largely due to the psycho-acoustic cues they sense from the human binaural hearing system evolved over millennia. Modern acoustic signal processing is just now beginning to be able to deliver that same experience to users remotely located from each other. This includes the ability to communicate in full duplex with wider bandwidths and multiple audio streams (e.g. stereo, 3D audio). It also involves locating and separating audio sources, suppressing noise, and using sound to automatically steer video cameras. Acoustic Signal Processing for Telecommunication presents digital signal processing techniques for telecommunications acoustics that are both cutting-edge and practical. Each chapter presents material that has not appeared in book form before and yet is easily realizable in today's technology. To this end, both new theory and new implementation techniques are presented. Topics include new adaptive filtering algorithms, multi-channel acoustic echo cancellation, noise control, virtual sound, sound source localization for camera tracking, source separation, and microphone arrays. Reader Reviews Topics are carefully selected. Good coverage of both traditional and cutting-edge new theories and algorithms. Less errors than a normal technique book. Only key derivations are outlined with others just omitted. This makes it easy to follow for an engineer like me but i suppose an academic researcher may dislike it somewhat. Unfortunately, too few results are given for each algorithm. Readers don't know if the algorithms have the potential to meet the various requirements of EC, i.e., residue error, convergence rate, complexity, numerical stability. (By the way, even a simple touch of industry standard of AEC might be helpful for this book) Anyway, for anyone who is interested in either accademic research or implementation of EC, i guess this book gives him/her a solid starting point.
