The chapters are written by international authors from diverse backgrounds who provide multidisciplinary perspectives on sound in its linear forms. The volume is designed as a textbook for students and teachers, as a handbook for researchers in sound, media and experience, and as a survey of key trends and ideas for practitioners interested in exploring the boundaries of their profession.
Simon Grimm examines new multi-microphone signal processing strategies that aim to achieve noise reduction and dereverberation. Therefore, narrow-band signal enhancement approaches are combined with broad-band processing in terms of directivity based beamforming. Previously introduced formulations of the multichannel Wiener filter rely on the second order statistics of the speech and noise signals. The author analyses how additional knowledge about the location of a speaker as well as the microphone arrangement can be used to achieve further noise reduction and dereverberation.

Sound Inventions is a collection of 34 articles taken from Experimental Musical Instruments, the seminal journal published from 1984 through 1999. In addition to the selected articles, the editors have contributed introductory essays, placing the material in cultural and temporal context, providing an overview of the field both before and after the time of original publication. The Experimental Musical Instruments journal contributed extensively to a number of sub-fields, including sound sculpture and sound art, sound design, tuning theory, musical instrument acoustics, timbre and timbral perception, musical instrument construction and materials, pedagogy, and contemporary performance and composition. This book provides a picture of this important early period, presenting a wealth of material that is as valuable and relevant today as it was when first published, making it essential reading for anyone researching, working with or studying sound.
With Computational Thinking in Sound, veteran educators Gena R. Greher and Jesse M. Heines provide the first book ever written for music fundamentals educators which is devoted specifically to music, sound, and technology. The authors demonstrate how the range of mental tools in computer science - for example, analytical thought, system design, and problem design and solution - can be fruitfully applied to music education, including examples of successful student work. While technology instruction in music education has traditionally focused on teaching how computers and software work to produce music, Greher and Heines offer context: a clear understanding of how music technology can be structured around a set of learning challenges and tasks of the type common in computer science classrooms. Using a learner-centered approach that emphasizes project-based experiences, the book provides music educators with multiple strategies to explore, create, and solve problems with music and technology in equal parts. It also provides examples of hands-on activities which encourage students, alone and in interdisciplinary groups, to explore the basic principles that underlie today's music technology and which expose them to current multimedia development tools.

Why don't Guitar Hero players just pick up real guitars? What happens when millions of people play the role of a young black gang member in Grand Theft Auto: San Andreas? How are YouTube-based music lessons changing the nature of amateur musicianship? This book is about play, performance, and participatory culture in the digital age. Miller shows how video games and social media are bridging virtual and visceral experience, creating dispersed communities who forge meaningful connections by "playing along" with popular culture. Playing Along reveals how digital media are brought to bear in the transmission of embodied knowledge: how a Grand Theft Auto player uses a virtual radio to hear with her avatar's ears; how a Guitar Hero player channels the experience of a live rock performer; and how a beginning guitar student translates a two-dimensional, pre-recorded online music lesson into three-dimensional physical practice and an intimate relationship with a distant teacher. Through a series of engaging ethnographic case studies, Miller demonstrates that our everyday experiences with interactive digital media are gradually transforming our understanding of musicality, creativity, play, and participation.

Cross-Word Modeling for Arabic Speech Recognition utilizes phonological rules in order to model the cross-word problem, a merging of adjacent words in speech caused by continuous speech, to enhance the performance of continuous speech recognition systems. The author aims to provide an understanding of the cross-word problem and how it can be avoided, specifically focusing on Arabic phonology using an HHM-based classifier.
Automatic speech recognition (ASR) systems are finding increasing use in everyday life. Many of the commonplace environments where the systems are used are noisy, for example users calling up a voice search system from a busy cafeteria or a street. This can result in degraded speech recordings and adversely affect the performance of speech recognition systems. As the use of ASR systems increases, knowledge of the state-of-the-art in techniques to deal with such problems becomes critical to system and application engineers and researchers who work with or on ASR technologies. This book presents a comprehensive survey of the state-of-the-art in techniques used to improve the robustness of speech recognition systems to these degrading external influences. Key features: Reviews all the main noise robust ASR approaches, including signal separation, voice activity detection, robust feature extraction, model compensation and adaptation, missing data techniques and recognition of reverberant speech.Acts as a timely exposition of the topic in light of more widespread use in the future of ASR technology in challenging environments.Addresses robustness issues and signal degradation which are both key requirements for practitioners of ASR.Includes contributions from top ASR researchers from leading research units in the field
Digital technology has changed the ways in which music is perceived, stored, distributed, mediated and created. The world of music is now a vast and complex jungle, teeming with CDs, MP3s, concerts, clubs, festivals, conferences, exhibitions, installations, websites, software programmes, scenes, Ideas and competing theories. In the eye of the storm stands David Toop, shedding light on the most interesting music now being made - on laptops, In downtown bars in Tokyo, wherever he finds it. Haunted Weather is part personal memoir and part travel journal, as well as an intensive survey of recent developments in digital technology, sonic theory and musical practice. Along the way Toop probes into the meaning of sound (and silence), offering fascinating insights into how computers can be used for improvisation. His wealth of musical knowledge provides inspiration for anyone interested in music.
We are surrounded by noise; we must be able to separate the signals we want to hear from those we do not. To overcome this 'cocktail party effect' we have developed various strategies; endowing computers with similar abilities would enable the development of devices such as intelligent hearing aids and robust speech recognition systems. This book describes a system which attempts to separate multiple, simultaneous acoustic sources using strategies based on those used by humans. It is both a review of recent work on the modelling of auditory processes, and a presentation of a new model in which acoustic signals are decomposed into elements. These structures are then re-assembled in accordance with rules of auditory organisation which operate to bind together elements that are likely to have arisen from the same source. The model is evaluated by measuring its ability to separate speech from a wide variety of other sounds, including music, phones and other speech.

This work addresses this problem in the short-time Fourier transform (STFT) domain. We divide the general problem into five basic categories depending on the number of microphones being used and whether the interframe or interband correlation is considered. The first category deals with the single-channel problem where STFT coefficients at different frames and frequency bands are assumed to be independent. In this case, the noise reduction filter in each frequency band is basically a real gain. Since a gain does not improve the signal-to-noise ratio (SNR) for any given subband and frame, the noise reduction is basically achieved by liftering the subbands and frames that are less noisy while weighing down on those that are more noisy. The second category also concerns the single-channel problem. The difference is that now the interframe correlation is taken into account and a filter is applied in each subband instead of just a gain. The advantage of using the interframe correlation is that we can improve not only the long-time fullband SNR, but the frame-wise subband SNR as well. The third and fourth classes discuss the problem of multichannel noise reduction in the STFT domain with and without interframe correlation, respectively. In the last category, we consider the interband correlation in the design of the noise reduction filters. We illustrate the basic principle for the single-channel case as an example, while this concept can be generalized to other scenarios. In all categories, we propose different optimization cost functions from which we derive the optimal filters and we also define the performance measures that help analyzing them.
