Automatic Parameter Calibration for Frequency Modulated Sound Synthesis with a Faster Differential Evolution
Authors: ,
Abstract: Frequency Modulated sound synthesis is a technique widely used for replicating sound of a natural music instruments to use it in a computer sound synthesizer. Many sound synthesis technique have been successful in reproducing the sounds of musical instruments. Sound synthesis techniques require parameter calibration. However, this task can be difficult and time consuming because of the non-linear parameter space. Two difficult challenges have to handle for synthesizing sound, that is-proper parameter extraction from a difficult search space and search time, which matters for a real time application. This article presents an application of stagnation adaptive DE scheme for faster parameter identification of a FM synthesized sound to match an unknown target sound. The simulation result shows that DE can perfectly reproduce the sound signal over other algorithm and also have a very faster convergence rate than classic DE.
