  • Patent number: 6667433
    Abstract: A quadratic phase interpolation method for synthesis of musical tones incorporates both phase and frequency measurements at the boundaries of a data frame using a weighted least square algorithm approach. The approach assumes that the true frequency and phase at the two ends of a data frame conform to a quadratic phase model and that exact match between measured phase and frequency with the quadratic model is not necessary because of the noise in the measurements.

  • Patent number: 6259014
    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.
