Over the last century, developments in electronic music and art have enabled new possibilities for creating audio and audio-visual artworks. With this new potential has come the possibility for representing subjective internal conscious states, such as the experience of hallucinations, using digital technology. Combined with immersive technologies such as virtual reality goggles and high-quality loudspeakers, the potential for accurate simulations of conscious
encounters such as Altered States of Consciousness (ASCs) is rapidly advancing. In Inner Sound, author Jonathan Weinel traverses the creative influence of ASCs, from Amazonian chicha
festivals to the synaesthetic assaults of neon raves; and from an immersive outdoor electroacoustic performance on an Athenian hilltop to a mushroom trip on a tropical island in virtual reality. Beginning with a discussion of consciousness, the book explores how our subjective realities may change during states of dream, psychedelic experience, meditation, and trance. Taking a broad view across a wide range of genres, Inner Sound draws connections between shamanic art and music, and
the modern technoshamanism of psychedelic rock, electronic dance music, and electroacoustic music. Going beyond the sonic into the visual, the book also examines the role of altered states in film, visual
music, VJ performances, interactive video games, and virtual reality applications. Through the analysis of these examples, Weinel uncovers common mechanisms, and ultimately proposes a conceptual model for Altered States of Consciousness Simulations (ASCSs). This theoretical model describes how sound can be used to simulate various subjective states of consciousness from a first-person perspective, in an interactive context. Throughout the book, the ethical issues
regarding altered states of consciousness in electronic music and audio-visual media are also examined, ultimately allowing the reader not only to consider the design of ASCSs, but also the implications of
their use for digital society.
