Modal Array Signal Processing : Principles and Applications of Acoustic Wavefield Decomposition
Many applications of acoustic signal processing, such as teleconferencing and surveillance systems, require an estimate of several parameters present in the observed acoustic wavefield. The most important parameters are the number as well as the location of active acoustic sources. This book deals with the problem of detecting and localizing multiple simultaneously active wideband acoustic sources by applying the notion of wavefield decomposition using circular and spherical microphone arrays. The decomposed wavefield representation is used to serve as a basis for so-called modal array signal processing algorithms, which have the significant advantage over classical array signal processing algorithms that they inherently support multiple wideband acoustic sources. A rigorous derivation of modal array signal processing algorithms for unambiguous source detection and localization as well as performance evaluations by means of measurements using an actual real-time capable implementation are discussed.

This book constitutes the thoroughly refereed post-proceedings of the Third International Computer Music Modeling and Retrieval Symposium, CMMR 2005. the papers address a broad variety of topics. The papers are organized in topical sections on sound synthesis; music perception and cognition; interactive music: interface, interaction, gestures and sensors, music composition; music retrieval: music performance, music analysis, music representation; as well as interdisciplinarity and computer music.
Computer Music Modeling and Retrieval ; Vol. 3310
This volume contains the final proceedings for the 2004 Computer Music Model-ing and Retrieval Symposium (CMMR 2004). CMMR is an annualevent focusing on important aspects of computer music. CMMR 2004 is the sec-ond event in this series. The use of computers in music is well established. CMMR 2004 provided aunique opportunity to meet and interact with peers concerned with the cross-influence of the technological and creative in computer music. The field of com-puter music is interdisciplinary by nature and closely related to a number of com-puter science and engineering areas such as information retrieval, programming,human computer interaction, digital libraries, hypermedia, artificial intelligence,acoustics, signal processing, etc. The event gathered many interesting people(researchers, educators, composers, performers, and others). There were manyhigh-quality keynote and paper presentations, that fostered inspiring discussions.
Acoustic MIMO Signal Processing
Telecommunication systems and human-machine interfaces start employing multiple microphones and loudspeakers in order to make conversations and interactions more lifelike, hence more efficient. This development gives rise to a variety of acoustic signal processing problems under multiple-input multiple-output (MIMO) scenarios, encompassing distant speech acquisition, sound source localization and tracking, echo and noise control, source separation and speech dereverberation, and many others. The last decade has witnessed a growing interest in exploring these problems, but there has been little effort to develop a theory to have all these problems investigated in a unified framework. This unique book attempts to fill the gap.
