With a continuously increasing desire for natural and comfortable human/machine interaction, the acoustic interface of any terminal for multimedia or telecommunication services is challenged to allow seamless and hands-free audio communication. Sound Capture for Human-Machine Interfaces introduces the practical aspects of microphone array signal processing and presents various combinations of beamforming and acoustic echo cancellation.

A comprehensive guide that addresses the theory and practice of spatial audio This book provides readers with the principles and best practices in spatial audio signal processing. It describes how sound fields and their perceptual attributes are captured and analyzed within the time-frequency domain, how essential representation parameters are coded, and how such signals are efficiently reproduced for practical applications. The book is split into four parts starting with an overview of the fundamentals. It then goes on to explain the reproduction of spatial sound before offering an examination of signal-dependent spatial filtering. The book finishes with coverage of both current and future applications and the direction that spatial audio research is heading in. Parametric Time-frequency Domain Spatial Audio focuses on applications in entertainment audio, including music, home cinema, and gaming—covering the capturing and reproduction of spatial sound as well as its generation, transduction, representation, transmission, and perception. This book will teach readers the tools needed for such processing, and provides an overview to existing research. It also shows recent up-to-date projects and commercial applications built on top of the systems. Provides an in-depth presentation of the principles, past developments, state-of-the-art methods, and future research directions of spatial audio technologies Includes contributions from leading researchers in the field Offers MATLAB codes with selected chapters An advanced book aimed at readers who are capable of digesting mathematical expressions about digital signal processing and sound field analysis, Parametric Time-frequency Domain Spatial Audio is best suited for researchers in academia and in the audio industry.

In the past few years we have written and edited several books in the area of acousticandspeechsignalprocessing. Thereasonbehindthisendeavoristhat there were almost no books available in the literature when we ?rst started while there was (and still is) a real need to publish manuscripts summarizing the most useful ideas, concepts, results, and state-of-the-art algorithms in this important area of research. According to all the feedback we have received so far, we can say that we were right in doing this. Recently, several other researchers have followed us in this journey and have published interesting books with their own visions and perspectives. The idea of writing a book on Microphone Array Signal Processing comes from discussions we have had with many colleagues and friends. As a c- sequence of these discussions, we came up with the conclusion that, again, there is an urgent need for a monograph that carefully explains the theory and implementation of microphone arrays. While there are many manuscripts on antenna arrays from a narrowband perspective (narrowband signals and narrowband processing), the literature is quite scarce when it comes to s- sor arrays explained from a truly broadband perspective. Many algorithms for speech applications were simply borrowed from narrowband antenna - rays. However, a direct application of narrowband ideas to broadband speech processing may not be necessarily appropriate and can lead to many m- understandings.

This book discusses various applications of machine learning using a new approach, the dynamic wavelet fingerprint technique, to identify features for machine learning and pattern classification in time-domain signals. Whether for medical imaging or structural health monitoring, it develops analysis techniques and measurement technologies for the quantitative characterization of materials, tissues and structures by non-invasive means. Intelligent Feature Selection for Machine Learning using the Dynamic Wavelet Fingerprint begins by providing background information on machine learning and the wavelet fingerprint technique. It then progresses through six technical chapters, applying the methods discussed to particular real-world problems. Theses chapters are presented in such a way that they can be read on their own, depending on the reader’s area of interest, or read together to provide a comprehensive overview of the topic. Given its scope, the book will be of interest to practitioners, engineers and researchers seeking to leverage the latest advances in machine learning in order to develop solutions to practical problems in structural health monitoring, medical imaging, autonomous vehicles, wireless technology, and historical conservation.

Vibe Merchants offers an insider’s perspective on the development of Jamaican Popular Music, researched and analysed by a thirty-year veteran with a wide range of experience in performance, production and academic study. This rare perspective, derived from interviews and ethnographic methodologies, focuses on the actual details of music-making practice, rationalized in the context of the economic and creative forces that locally drive music production. By focusing on the work of audio engineers and musicians, recording studios and recording models, Ray Hitchins highlights a music creation methodology that has been acknowledged as being different to that of Europe and North America. The book leads to a broadening of our understanding of how Jamaican Popular Music emerged, developed and functions, thus providing an engaging example of the important relationship between music, technology and culture that will appeal to a wide range of scholars.

FX introduces today's up and coming musician to the fantastic creative potential of the most popular instrument today- the home studio. Explaining the basic and advanced signal processing techniques used in professional music production (EQ, compression, delay, reverb etc), using real world popular music examples and an emphasis on the perceptual results and musical value of these effects, FX teaches the Recording Musician how to achieve professional production standards and maximise their creative potential. The accompanying website www.soundfx-companion.com includes audio exaples of FX featured in the book. Features: A chapter dedicated to each key effect: Distortion Equalization Compression and Limiting Delay Expansion and Gating Pitch Shift Reverb Volume More than 100 line drawings and illustrations. Accompanying website featuring examples of all FX covered in the book. Discography of FX at the end of each relevant chapter. From the Sound FX Intro: The most important music of our time is recorded music. The recording studio is its principle musical instrument. The recording engineers and music producers who create the music we love know how to use signal processing equipment to capture the work of artists, preserving realism or altering things wildly, as appropriate. While the talented, persistent, self-taught engineer can create sound recordings of artistic merit, more productive use of the studio is achieved through study, experience and collaboration. This book defines the technical basis of the most important signal processing effects used in the modern recording studio, highlights the key drivers of sound quality associated with each, shares common production techniques used by recording engineers with significant experience in the field, references many of the touchstone recordings of our time, and equips the reader with the knowledge needed to comfortably use effects devices correctly, and, more importantly, to apply these tools creatively.

Provides the reader with a practical introduction to the wide range of important concepts that comprise the field of digital speech processing. Students of speech research and researchers working in the field can use this as a reference guide.
