I have an article in The Oxford Handbook of Music and Virtuality (2016), edited by the late Sheila Whiteley and Shara Rambarran. The book’s thirty-one chapters, write the editors, examine “the intersections, mutations, and transmigrations of the virtual and the real” by offering “a kaleidoscope of interdisciplinary perspectives from scholars around the globe on the way in which virtuality mediates the dissemination, acquisition, performance, creation, and reimagining of music.” My article “From Environmental Sound To Virtual Environment Enhancing” explores the history, design, uses, and social meanings of Ambiance, a popular soundscape app.
