Pyschoacoustics (the science of hearing/audition) can be explored and exploited in computer music.
Musical examples played in class on 10/23/07 include solo saxophone music by Eric Barber, Ugandan amadinda (wooden xylophone) music from the Demonstrations of Auditory Scene Analysis CD, and the Headphone Canon by Nick Didkovsky.
Researcher David Huron classifies 8 primary auditory phenomena: loudness, pitch, timbre, toneness, apparent location, auditory streaming, numerosity, sensory dissonce. More info can be found in his Music Cognition Handbook: A Glossary of Concepts: .
Pd lab#3/hw#3 [] involves auditory streaming. A visual analogy is given in the lab.
Several psychology lab examples of auditory streaming have been created by Albert Bregman and Pierre Ahad at the Auditory Perception Laboratory, McGill University (Montreal) and are available on the Demonstrations of Auditory Scene Analysis CD which provides examples of phenomena discussed in Bregman's 1990 book, Auditory Scene Analysis: The Perceptual Organization of Sound, a core text that reports on hypotheses and experiments.
