Capturing, recording and broadcasting the voice is often difficult. Many factors must be taken into account and achieving a true representation is much more complex than one might think. The capture devices such as the position of the singer(s) or narrator(s), the acoustics, atmosphere and equipment are just some of the physical aspects that need to be mastered. Then there is the passage through the analog or digital channel, which disrupts the audio signal, as well as the processes that are often required to enrich, improve or even transform the vocal timbre and tessitura. While in the past these processes were purely material, today digital technologies and software produce surprising results that every professional in recording and broadcasting should know how to master. Recording and Voice Processing 1 addresses some general theoretical concepts. A history of recording and the physiology of the vocal apparatus are detailed in order to give the reader an understanding of the fundamental aspects of the subject. This volume also includes an advanced study of microphones, addressing their characteristics and typologies. The acoustic environment and its treatment are also considered in terms of the location of the sound capture - whether in a home studio, recording studio, live or natural environment - in order to achieve a satisfactory sound recording.
Sensors for Ranging and Imaging is a comprehensive textbook and professional reference that provides a solid background in active sensing technology.

The core of the book is concerned with active sensing, starting with active ranging and active imaging sensors (operational principles, components), and goes through the derivation of the radar (and lidar) range equations, and the detection of echo signals, both fundamental to the understanding of radar, sonar and lidar imaging. Further chapters cover signal propagation of both electromagnetic and acoustic energy, and target and clutter characteristics. The remainder of the book involves the basics of the range measurement process, active imaging with an emphasis on noise and linear frequency modulation techniques, Doppler processing, and target tracking. This systematic and thorough guide to ranging and imaging sensors is invaluable for graduate students studying sensing systems and industry professionals wishing to expand or update their knowledge. It offers clear, detailed explanations alongside worked examples to provide readers with an in-depth understanding of the material.
On March 15, 2011, Donald Trump changed television forever. The Comedy Central Roast of Trump was the first major live broadcast to place a hashtag in the corner of the screen to encourage real-time reactions on Twitter, generating more than 25,000 tweets and making the broadcast the most-watched Roast in Comedy Central history. The #trumproast initiative personified the media and tech industries' utopian vision for a multiscreen and communal live TV experience. In Social TV: Multiscreen Content and Ephemeral Culture, author Cory Barker reveals how the US television industry promised-but failed to deliver-a social media revolution in the 2010s to combat the imminent threat of on-demand streaming video. Barker examines the rise and fall of Social TV across press coverage, corporate documents, and an array of digital ephemera. He demonstrates that, despite the talk of disruption, the movement merely aimed to exploit social media to reinforce the value of live TV in the modern attention economy. Case studies from broadcast networks to tech start-ups uncover a persistent focus on community that aimed to monetize consumer behavior in a transitionary industry period. To trace these unfulfilled promises and flopped ideas, Barker draws upon a unique mix of personal Social TV experiences and curated archives of material that were intentionally marginalized amid pivots to the next big thing. Yet in placing this now-forgotten material in recent historical context, Social TV shows how the era altered how the industry pursues audiences. Multiscreen campaigns have shifted away from a focus on live TV and toward all-day "content" streams. The legacy of Social TV, then, is the further embedding of media and promotional material onto every screen and into every moment of life.
