This book evaluates the impact of relevant factors affecting the results of speech quality assessment studies carried out in crowdsourcing. The author describes how these factors relate to the test structure, the effect of environmental background noise, and the influence of language differences. He details multiple user-centered studies that have been conducted to derive guidelines for reliable collection of speech quality scores in crowdsourcing. Specifically, different questions are addressed such as the optimal number of speech samples to include in a listening task, the influence of the environmental background noise in the speech quality ratings, as well as methods for classifying background noise from web audio recordings, or the impact of language proficiency in the user perception of speech quality. Ultimately, the results of these studies contributed to the definition of the ITU-T Recommendation P.808 that defines the guidelines to conduct speech quality studies in crowdsourcing.

What is this sound? What does that sound indicate? These are two questions frequently heard in daily conversation. Sound results from the vibrations of elastic media and in daily life provides informative signals of events happening in the surrounding environment. In interpreting auditory sensations, the human ear seems particularly good at extracting the signal signatures from sound waves. Although exploring auditory processing schemes may be beyond our capabilities, source signature analysis is a very attractive area in which signal-processing schemes can be developed using mathematical expressions. This book is inspired by such processing schemes and is oriented to signature analysis of waveforms. Most of the examples in the book are taken from data of sound and vibrations; however, the methods and theories are mostly formulated using mathematical expressions rather than by acoustical interpretation. This book might therefore be attractive and informative for scientists, engineers, researchers, and graduate students who are interested in the mathematical representation of signals and the applications of Fourier analysis. The book can be described as being practically self-contained but does assume readers are familiar with introductory topics in discrete signal processing, as in the discrete Fourier transform. Hence this book might be also usable as a textbook in graduate courses in applied mathematics on topics such as complex functions. Almost all scientific phenomena are sensed as waves propagating in some space. Over the years, waveform analysis has therefore been one of the resilient academic areas of study and still is seen as fertile ground for development. In particular, waveform analysis based on the theory of linear systems would be a good example where a physical interpretation can be given to the mathematical theory of complex functions in terms of magnitude, angle, poles, and zeros of complex functions. For readers who are interested in the physical aspects of sound and vibration data or elementary formulation of wave equations and their solutions, the book Sound and Signals by M. Tohyama (Springer 2011) is recommended. It can serve as a complementary companion to this present volume or independently as a good reference.

Known as the "Father of Festival Sound," Bill Hanley (b. 1937) made his indelible mark as a sound engineer at the 1969 WoodStock Music and Arts Fair. Hanley is credited with creating the sound of WoodStock, which literally made the massive festival possible. Stories of his on-the-fly solutions resonate as legend among festivalgoers, music lovers, and sound engineers. Since the 1950s his passion for audio has changed the way Audiences listen to and technicians approach quality live concert sound. John Kane examines Hanley's echoing impact on the entire field of sound engineering, that crucial but often-overlooked carrier wave of contemporary music. Hanley's innovations founded the sound reinforcement industry and launched a new area of technology, rich with clarity and intelligibility. By the early seventies the post-WoodStock festival mass gathering movement collapsed. The music industry shifted, and new sound companies surfaced. After huge financial losses and facing stiff competition, Hanley lost his hold on a business he helped create. By studying both his history during the festivals and his independent business ventures, Kane seeks to present an honest portrayal of Hanley and his acumen and contributions. Since 2011, Kane conducted extensive research, including over one hundred interviews with music legends from the Production and performance side of the industry. These carefully selected respondents witnessed Hanley's expertise at various events and venues like Lyndon B. Johnson's second inauguration, the Newport Folk/Jazz Festivals, the Beatles' final tour of 1966, the Fillmore East, Madison Square Garden, and more. The Last Seat in the House will intrigue and inform anyone who cares about the modern music industry.
