.COVER("2",|AN EXPLORATION OF MUSICAL TIMBRE|,
."John M. Grey",,,February 1975);
%1Due to its overwhelming complexity, timbre perception is a poorly
understood subject in the field of auditory
perception. Computer-based research tools have been developed that
appear to be important for an investigation of timbre perception. 
In the work to be described,
an exploratory approach was formulated for dealing with 
this highly multidimensional attribute of sound. This approach
utilized a computer technique for the synthesis of musical timbres
based on the analysis of natural instrument tones. 
This technique was useful for generating stimuli in timbre experiments 
because of its to effectiveness in allowing the investigator to
specify and manipulate the physical properties of
complex time-variant tones. An important discovery resulted suggesting
that naturalistic tones can be synthesized from
a vastly simplified set of physical properties.
These simplified tones were useful as stimuli in further studies on timbre 
perception because of the great reduction in the number of physical factors
to be considered in making psychophysical interpretations of
perceptual data.
