Maryanne Amacher was an American composer, performer and multi-media installation artist known internationally for her dramatic architectural staging of music and sound. She worked extensively with the physiological phenomenon called otoacoustic emission, in which the ears themselves act as aurally active generating devices. Amacher did musical training in Philadelphia, and also Austria and England.
From 1962 to 1964 she studied with George Rochberg and Karlheinz Stockhausen at the University of Pennsylvania, where she graduated with a bachelor's degree. She then worked in acoustics and computer science at the University of Illinois at Urbana-Champaign. In 1967 she created the piece "City Links: Buffalo", which was made with five microphones situated in different parts of the city and lasted 28 hours. It was broadcast live by radio station WBFO. Later pieces deal with the acoustics of locations and architectural buildings. Amacher was also a member of the improvisation ensemble Musica Elettronica Viva. She worked with a wide range of artists including David Behrman, Scott Fisher, Mark Trayle, Frederic Rzewski and Alvin Curran, and was active as a composer-performer in the field of sound installation with Ars Acustica.
In 1986, she was a guest of the DAAD Artists Program in Berlin and most recently, she taught at Bard College. In 2005 she was awarded the Prix Ars Electronica in the Digital Musics category for their project "TEO! A Sonic sculpture".
