About this product
- DescriptionThis book collects a wealth of information about spatial audio coding into one comprehensible volume. It is a thorough reference to the 3GPP and MPEG Parametric Stereo standards and the MPEG Surround multi-channel audio coding standard. It describes key developments in coding techniques, which is an important factor in the optimization of advanced entertainment, communications and signal processing applications. Until recently, techlogies for coding audio signals, such as redundancy reduction and sophisticated source and receiver models did t incorporate spatial characteristics of source and receiving ends. Spatial audio coding achieves much higher compression ratios than conventional coders. It does this by representing multi-channel audio signals as a downmix signal plus side information that describes the perceptually-relevant spatial information. Written by experts in spatial audio coding, Spatial Audio Processing: * reviews psychoacoustics (the relationship between physical measures of sound and the corresponding percepts) and spatial audio sound formats and reproduction systems;* brings together the processing, acquisition, mixing, playback, and perception of spatial audio, with the latest coding techniques;* analyses algorithms for the efficient manipulation of multiple, discrete and combined spatial audio channels, including both MP3 and MPEG Surround;* shows how the same insights on source and receiver models can also be applied for manipulation of audio signals, such as the synthesis of virtual auditory scenes employing head-related transfer function (HRTF) processing and stereo to N-channel audio upmix. Audio processing research engineers and audio coding research and implementation engineers will find this an insightful guide. Academic audio and psychoacoustic researchers, including post-graduate and third/fourth year students taking courses in signal processing, audio and speech processing, and telecommunications, will also benefit from the information inside.
- Author BiographyJeroen Breebaart was born in the Netherlands in 1970. He studies biomedical engineering at the technical University Eindhoven. He received his PhD degree in 2001 from the Institute for Perception research (IPO) in the field of mathematical models of human spatial hearing. Currently, he is a senior scientist with Philips research. His main fields of interest and expertise are spatial hearing, parametric stereo and multi-channel audio coding, automatic audio content analysis, and generic digital audio signal processing algorithms. He published several papers on binaural hearing, binaural modeling, and spatial audio coding. His work is incorporated in several international audio compression standards such as MPEG-4, 3GPP, and MPEG Surround. Christof Faller received an MS (Ing) degree in electrical engineering from ETH Zurich, Switzerland, in 2000, and a PhD degree for his work on parametric multi-channel audio coding from EPFL, Switzerland, in 2004. From 2000 to 2004 he worked in the Speech and Acoustics Research Department at bell Laboratories, Lucent Technologies and Agere Systems (a Lucent Company), where he worked on audio coding for digital satellite radio, including parametric multi-channel audio coding. He is currently a part-time postdoctoral employee at EPFL. In 2006 he founded Illusonic LLC, an audio and acoustics research company. Dr Faller has won a number of awards for his contributions to spatial audio coding, MP3 surround, and MPEG surround. His main current research interests are spatial hearing and spatial sound capture processing, and reproduction.
