MUSICAL SOUND SIGNAL SYNTHESIS SYSTEM

摘要

PURPOSE:To enable complicate variable control over a musical sound waveform corresponding to an exponential function by synthesizing a musical sound signal according to the execution result of specific arithmetic algorithm. CONSTITUTION:A waveform generating means 2 outputs a wave form function f(omegat) according to phase information omegat which is outputted by a phase information generating means 1 and varies repeatedly. This function is raised by a power means 3 according to an exponent (k) from an exponent function specifying means 4 to calculate and determine an exponential function [f(omegat)] by specific arithmetic algorithm execution, thereby synthesizing the musical sound waveform. Then the exponent (k) varies according to omegat applied to the means 4 and a synthesized musical sound waveform corresponding to the exponential function is varied and controlled complicatedly.
