Computer Analysis of the Auditory Characteristics of Musical Performance. Final Report.
Heller, Jack J.; Campbell, Warren C.
The purpose of this research was to perform computer analysis and modification of complex musical tones and to develop models of perceptual and learning processes in music. Analysis of the physical attributes of sound (frequency, intensity, and harmonic content, versus time) provided necessary information about the musical parameters of intonation, vibrato, dynamics, and rhythm. A general purpose digital computer and appropriate analog devices were utilized to analyze and synthesize complex musical tones. The procedures included the transformation of audio tapes of music to digital tapes via a high speed analog-to-digital converter system. The significance of the research is based on the belief that: 1) objectifying certain parameters of musical performance will have a direct bearing on behavioral goals and methods of music education; and, 2) an understanding of the total problem of human information processing requires a detailed investigation of structured non-verbal stimuli in the auditory mode. Two supplementary investigations are included: Computer Analysis of Musical Performance, by Warren C. Campbell (Appendix I) and The Effects of the Attack Transient on Aural Recognition of Instrumental Timbres, by Ralph C. Thayer, Jr. (Appendix II). Appendix III, Computer Analysis System Software, by Jack Owens, describes a library of computer programs used to perform certain basic mathematical analyses of the digitized musical performances.
