A quest to find something new by excavating the "deep time" of media's development—not by simply looking at new media's historic forerunners, but by connecting models, machines, technologies, and accidents that have until now remained separated. Deep Time of the Media takes us on an archaeological quest into the hidden layers of media development—dynamic moments of intense activity in media design and construction that have been largely ignored in the historical-media archaeological record. Siegfried Zielinski argues that the history of the media does not proceed predictably from primitive tools to complex machinery; in Deep Time of the Media, he illuminates turning points of media history—fractures in the predictable—that help us see the new in the old. Drawing on original source materials, Zielinski explores the technology of devices for hearing and seeing through two thousand years of cultural and technological history. He discovers the contributions of "dreamers and modelers" of media worlds, from the ancient Greek philosopher Empedocles and natural philosophers of the Renaissance and Baroque periods to Russian avant-gardists of the early twentieth century. "Media are spaces of action for constructed attempts to connect what is separated," Zielinski writes. He describes models and machines that make this connection: including a theater of mirrors in sixteenth-century Naples, an automaton for musical composition created by the seventeenth-century Jesuit Athanasius Kircher, and the eighteenth-century electrical tele-writing machine of Joseph Mazzolari, among others. Uncovering these moments in the media-archaeological record, Zielinski says, brings us into a new relationship with present-day moments; these discoveries in the "deep time" media history shed light on today's media landscape and may help us map our expedition to the media future.

A writer-musician examines how the switch from analog to digital audio is changing our perceptions of time, space, love, money, and power. Our voices carry farther than ever before, thanks to digital media. But how are they being heard? In this book, Damon Krukowski examines how the switch from analog to digital audio is changing our perceptions of time, space, love, money, and power. In Ways of Hearing—modeled on Ways of Seeing, John Berger's influential 1972 book on visual culture—Krukowski offers readers a set of tools for critical listening in the digital age. Just as Ways of Seeing began as a BBC television series, Ways of Hearing is based on a six-part podcast produced for the groundbreaking public radio podcast network Radiotopia. Inventive uses of text and design help bring the message beyond the range of earbuds. Each chapter of Ways of Hearing explores a different aspect of listening in the digital age: time, space, love, money, and power. Digital time, for example, is designed for machines. When we trade broadcast for podcast, or analog for digital in the recording studio, we give up the opportunity to perceive time together through our media. On the street, we experience public space privately, as our headphones allow us to avoid “ear contact” with the city. Heard on a cell phone, our loved ones' voices are compressed, stripped of context by digital technology. Music has been dematerialized, no longer an object to be bought and sold. With recommendation algorithms and playlists, digital corporations have created a media universe that adapts to us, eliminating the pleasures of brick-and-mortar browsing. Krukowski lays out a choice: do we want a world enriched by the messiness of noise, or one that strives toward the purity of signal only?

The field of spatial hearing has exploded in the decade or so since Jens Blauert's classic work on acoustics was first published in English. This revised edition adds a new chapter that describes developments in such areas as auditory virtual reality (an important field of application that is based mainly on the physics of spatial hearing), binaural technology (modeling speech enhancement by binaural hearing), and spatial sound-field mapping. The chapter also includes recent research on the precedence effect that provides clear experimental evidence that cognition plays a significant role in spatial hearing.The remaining four chapters in this comprehensive reference cover auditory research procedures and psychometric methods, spatial hearing with one sound source, spatial hearing with multiple sound sources and in enclosed spaces, and progress and trends from 1972 (the first German edition) to 1983 (the first English edition) -- work that includes research on the physics of the external ear, and the application of signal processing theory to modeling the spatial hearing process. There is an extensive bibliography of more than 900 items.
