COMPUTER MUSIC AT STANFORD
Deptartment of Music
Stanford University


Ten years ago Stanford began its support of computer music at a time
when many universities considered such work to be of marginal value.
We believed, however, that the audio-loudspeaker and the magnetic
tape recorder together formed the instrument of the future and that
the most promising and powerful means of control of this `instrument'
was by means of computers.

Subsequent research and musical compositions based on this research
have shown that computer and audio technology can extend the expressive
capability of musical composition in new and novel directions.  As an
example, our research in the simulation of moving sound sources has
added the dimension of space-sound sculpture as a parameter of
composition.  The development of relatively inexpensive,  high quality,
quadraphonic tape recorders has allowed us to take pieces using this
spatial technique out of the laboratory and into concert halls throughout
Europe and the United States.

All of the computer music research has been performed at the Stanford
Artificial Intelligence Laboratory.  Because of our growing and
specialized computing needs, Stanford is establishing the Center for
Computer Research in Music and Acoustics which will have a semi-
independent computer system.  In order to help in establishing the
center we have applied for and received a grant of $250,000 from the
National Science Foundation for research support and $100,000 from
the National Endowment for the Arts for purchase of part of the
equipment.  The center will be integrated into the instructional
program of the university as well as serve as an international resource
for guest composers and researchers.  In addition,
the center will coordinate its research projects with
the research institute to be directed by Pierre Boulez in Paris who
will visit with his team the Stanford center in August of this year
for a special seminar in the utilization of the current technology.


Existing Equipment:
	Audio-
		Sony 854-4 recorder
		Scully 280 recorder
		4 ch Dolby A
		4 Altec speakers and amplifiers
	Computer- (belonging to A.I. Lab)
		DEC PDP-10 computer (256k memory)
		38 graphics display terminals
		IBM 3330 disk system
		Xerox Graphics Printer
		4 ch digital to analog and anolog to digital converters

Proposed Equipment for center:
	Audio-
		2nd Sony 854-4
		8 ch recorder for 3 dimensional spatial experiments
		acoustically treated room and quiet booth
	Computer-
		PDP-10 type computer
		computer controled digital synthesizer
		3330 type disk
		4 graphic display terminals

Proposed research for the center:
	The continuation of our present research will involve further
development of digital signal processing techniques for the purpose
of the simulation of complex natural tones in reverberant spaces.
Fall-out from these research techniques should benefit the audio
industry, for example, they might allow the computer re-generation
of old recordings, such as Caruso, to hi-fidelity stereo quality.
Research results may also be of use in the eventual development of
digital tape recorders-reproducers.
