An Interactive Hybrid Computer System for Time Domain Audio Synthesis

摘要

A time domain oriented technique using periodic functions composed of first order segments was employed in the development of a real-time interactive computer audio synthesis system. A general purpose analog computer was programmed to create non-monotonic function generators which are used to generate sequences of periodic functions that can be frequency and amplitude modulated. The system is appropriate for experiments in psychoacoustics. Exploration of the relationships between the physical and the perceptual significance of synthesis parameters of the technique is aided by real-time frequency analysis programs and an audio output capability. The system includes an interactive graphics terminal for conversational I/O and conventional peripheral devices for creating permanent records. (Author)
