Sound Reproduction: The Acoustics and Psychoacoustics of Loudspeakers and Rooms, Third Edition explains the physical and perceptual processes that are involved in sound reproduction and demonstrates how to use the processes to create high-quality listening experiences in stereo and multichannel formats. Understanding the principles of sound production is necessary to achieve the goals of sound reproduction in spaces ranging from recording control rooms and home listening rooms to large cinemas. This revision brings new science-based perspectives on the performance of loudspeakers, room acoustics, measurements and equalization, all of which need to be appropriately used to ensure the accurate delivery of music and movie sound tracks from creators to listeners. The robust website (www.routledge.com/cw/toole) is the perfect companion to this necessary resource.
Designed to make life a little easier by providing all the theoretical background necessary to understand sound reproduction, backed up with practical examples. Specialist terms - both musical and physical - are defined as they occur and plain English is used throughout. Analog and digital audio are considered as alternatives, and the advantages of both are stressed. Audio is only as good as the transducers employed, and consequently microphone and loudspeaker technology also feature heavily - making this the most comprehensive, up-to-date text currently available on all aspects of sound reproduction.

DIVCultural study of the development of sound technology in the nineteenth and early twentieth centuries from telephones and stethoscopes to record players./div
During the twentieth century sound underwent a dramatic transformation as new technologies and social practices challenged conventional aural experience. As a result, sound functioned as a means to exert social, cultural, and political power in unprecedented and unexpected ways. The fleeting nature of sound has long made it a difficult topic for historical study, but innovative scholars have recently begun to analyze the sonic traces of the past using innovative approaches. Sound in the Age of Mechanical Reproduction investigates sound as part of the social construction of historical experience and as an element of the sensory relationship people have to the world, showing how hearing and listening can inform people's feelings, ideas, decisions, and actions. The essays in Sound in the Age of Mechanical Reproduction uncover the varying dimensions of sound in twentieth-century history. Together they connect a host of disparate concerns, from issues of gender and technology to contests over intellectual property and government regulation. Topics covered range from debates over listening practices and good citizenship in the 1930s, to Tokyo Rose and Axis radio propaganda during World War II, to CB-radio culture on the freeways of Los Angeles in the 1970s. These and other studies reveal the contingent nature of aural experience and demonstrate how a better grasp of the culture of sound can enhance our understanding of the past.

Explores the principles and practical considerations of spatial sound recording and reproduction. Particular emphasis is given to the increasing importance of multichannel surround sound and 3D audio, including binaural approaches, without ignoring conventional stereo. The enhancement of spatial quality is arguably the only remaining hurdle to be overcome in pursuit of high quality sound reproduction. The rise of increasingly sophisticated spatial sound systems presents an enormous challenge to audio engineers, many of whom are confused by the possibilities and unfamiliar with standards, formats, track allocations, monitoring configurations and recording techniques. The author provides a comprehensive study of the current state of the art in spatial audio, concentrating on the most widely used approaches and configurations. Anyone wishing to expand their understanding of these cutting-edge technologies will want to own this book.
This eBook provides the audio enthusiast with an easy-to-follow step-by-step guide for designing a custom digital filter that corrects the frequency and timing response of your loudspeakers in your listening environment so that the music arriving at your ears matches as closely as possible to the content on the recording.Industry guidelines, spanning over 40 years of evolution, are referenced throughout the eBook, providing the recommended target responses for accurate sound reproduction. Correcting the measured response to known target responses is, in effect, matching the acoustic output signal arriving at your ears to the digital audio stored in a media file. The target responses can also be tailored to your own preferences.The chapter on the acoustics and psychoacoustics of room correction explains why we hear what we hear in small-room acoustics and what our ears care about most when it comes to accurate sound reproduction. There are individual chapters on industry target responses for frequency and step response, group delay, energy time curve, reverb time, polar response and interaural coherence coefficient (i.e., imaging).Advanced sections of the eBook show you how to design and implement digital crossovers, driver linearization, and driver time alignment; how to compensate for brickwall antialiasing filters; and how to use the Beamforming quasi-anechoic measurement technique. All of these sections are designed to incrementally improve your sound reproduction system's accuracy. The last section of the eBook shows you how to perform loopback measurements to verify the design and operation of your digital correction filter, not only at the listening position, but across a wide listening area as well.Whether your sound reproduction system is a computer desktop speaker system, stereo audiophile system, home theater multi-channel system, mains and sub-woofer system, DIY audio system, or car sound system, the results are audible, measurable, and repeatable.To benefit the most from this step-by-step guide, you will require a computer, a calibrated measurement microphone, an Analog to Digital (ADC)/Digital to Analog (DAC) converter, and two commercial software packages: Acourate DSP Audio Toolbox and JRiver Media Center. This eBook contains several color-coded images, so viewing on a color screen is required.With over 260 color screen captures of the software in action, plus 200 links to industry reference material and knowledge, this eBook is the definitive guide to Accurate Sound Reproduction Using Digital Signal Processing (DSP).
This book first introduces the background of spatial audio reproduction, with different types of audio content and for different types of playback systems. A literature study on the classical and emerging Primary Ambient Extraction (PAE) techniques is presented. The emerging techniques aim to improve the extraction performance and also enhance the robustness of PAE approaches in dealing with more complex signals encountered in practice. The in-depth theoretical study helps readers to understand the rationales behind these approaches. Extensive objective and subjective experiments validate the feasibility of applying PAE in spatial audio reproduction systems. These experimental results, together with some representative audio examples and MATLAB codes of the key algorithms, illustrate clearly the differences among various approaches and also help readers gain insights on selecting different approaches for different applications.
