Abstract
In the Karplus-Strong method, the synthetic sound is obtained by exciting a recursive comb-filter with a burst of noise. An analysis scheme is presented in this paper, which makes it possible to derive the optimal Karplus-Strong synthesis parameters from the recording of a real instrument. In addition, an excitation signal can be calculated and used in place of the usual burst of white or colored noise, in order to obtain more realistic syntheses.
