ENGINEERING REPORTS - Estimating the Instantaneous Frequency of Sinusoidal Components Using Phase-Based Methods - A robust method to estimate the short-term spectra of an audio signal is important in many applications, such as sinusoidal modeling of music. Using a phase-based estimation approach, the authors prove five of these techniques are actually theoretically equivalent. But in a practical application, differences in performance among various estimation approaches result from assumptions about signal complexity and the implementation of the algorithms. A Hilbert filter in a preprocessing stage can improve the precision of frequency estimation.

PAPERS - High-Precision Fourier Analysis of Sounds Using Signal Derivatives - An original, modified Fourier transform greatly enhances the precision of Fourier analysis in its frequency and amplitude resolution capabilities. This new Fourier analysis is performed in a shorter time frame when compared to more conventional transforms. This method requires the computation of two small, discrete Fourier transforms instead of a single, much larger one. It is of great utility for extracting spectral modeling parameters in an extremely short time frame
