Electroacoustic music has inspired many of the creative sound design and audio processing tools available today, but the genre is often little known within sound design and music production circles. While these tools are a physical manifestation of electroacoustic music’s influence, the ideas and concepts of this art form also have a great potential to contribute and inspire sound design and music production practice. This chapter explores the ideas and practices of electroacoustic music, seeking to reconnect these complementary spheres, providing an introduction to more than a century of sonic practice and innovation that has resulted in a rich discourse for thinking about and composing sounds.
