Abstract

A method has been developed for estimating the parameters of virtual musical instrument synthesizers to obtain isolated instrument sounds without distortion and noise. First, a number of instrument sounds are generated from randomly generated parameters of a synthesizer. Lowlevel acoustic features and their delta features are extracted for each time frame and accumulated into statistics. Multiple linear regression is used to model the relationship between the acoustic features and instrument parameters. Experimental evaluations showed that the proposed method estimated parameters with a best case error of 0.004 and signal-to-distortion ratio of 17.35 dB, and reduced noise to smaller distortions in several cases.
