Abstract
This application describes a method for musical signal analysis and synthesis using global waveform fitting (GWF). GWF uses a sinusoidal model with quadratic phase. GWF tries to fit the entire data record (signal waveform) to the assumed signal model. The model parameters obtained by GWF have clear physical interpretations or meanings.
