Summer Workshops 1995

Introduction to Psychoacoustics and Psychophysics

With emphasis on the audio and haptic components of virtual reality design

Guest lecturers: Perry Cook (CCRMA), Louis Rosenberg (Immersion Corp.), Bill Verplank (Interval Research), Malcolm Slaney (Interval Research), Beth Wenzel (NASA), and others.

This course will introduce concepts and apply tools from cognitive psychology to the composition of virtual audio and haptic environments. In particular, the salience of various auditory and haptic phenomena to the perception and performance of music will be examined. Morning lectures will cover relevant topics from acoustics, psychology, physics and physiology. The goal is to apply principles of speech, timbre, melody, pitch, texture, and shape perception to tailor virtual objects to be convincingly touched and heard. Guest lectures by eminent researchers and entrepreneurs working in the fields of psychoacoustics and psychophysics will be featured. Afternoon labs will provide practical experience through numerous human-subject experiments. In addition to sound synthesis tools, various haptic interfaces will be available.

Introduction to Algorithmic Composition

This course introduces basic principles and techniques of algorithmic composition and covers topics such as data representation, techniques employing random selection, enveloping, algorithmic editing, pattern generation and scheduling. Sound synthesis as used in course examples will include MIDI, the (realtime) Music Kit and (non-realtime) Common Lisp Music and Common Music Notation. The course will be taught using the Common Music / Stella environment on NeXT workstations and on Macintoshes using the a newly developed graphical interface. The afternoon(morning) labs will be hands-on spectral and physical modeling using software such as SMS, MusicKit, SynthBuilder, and simple C-Code examples. The Yamaha synthesizers to be used in the course will include the VL-1 and SY-77. All source code and documents from the workshop including the graphic interface are free to take. No prior programming experience is assumed.

Advanced Projects in Algorithmic Composition

Topics are continued from the first course but emphasis is placed on developing programming skills while working on individual projects of the student's own choosing.

[Students may take the full 4 week course at a reduced tuition rate of $1400.]

Digital Signal Processing for Musicians:

Spectral and Physical Models

This course will cover analysis and synthesis of musical signals based on spectral and physical models. The course will be organized into morning lectures covering theoretical aspects of the models, and afternoon labs. The morning lectures will present topics such as Fourier theory, spectrum analysis, the phase vocoder, digital waveguides, digital filter theory, pitch detection, linear predictive coding (LPC), and various other aspects of signal processing of interest in musical applications. The afternoon labs will be hands-on spectral and physical modeling using software such as SMS, MusicKit, SynthBuilder, and simple C-Code examples. Familiarity with engineering, mathematics, physics, and programming is a plus, but the lectures and labs will be geared to a musical audience with basic experience in math and science. Most of the programs used in the workshop will be available to take.

Music Printing with Small Computers using SCORE

This course will cover the details of the use of the SCORE software program for the creation of publication-quality music typography on PC compatible computers. Emphasis will be placed on the production of individual participant's projects.

Annual Summer Concert

The annual concert of new music by CCRMA composers will take place during the Summer Workshops. It will be held in Frost Outdoor Amphitheater at Stanford on July 20, 1995.

Additional Information

Housing costs are not included in the course fee. Campus housing is available through the Stanford University Conference Office. No academic credit is offered for participation in the workshops.
