PARSHL: An Analysis/Synthesis Program for Non-Harmonic Sounds Based on a Sinusoidal Representation

This paper describes a peak-tracking spectrum analyzer, called Parshl, which is useful for extracting additive synthesis parameters from inharmonic sounds such as the piano. Parshl is based on the Short-Time Fourier Transform (STFT), adding features for tracking the amplitude, frequency, and phase trajectories of spectral lines from one FFT to the next. Parshl can be thought of as an “inharmonic phase vocoder” which uses tracking vocoder analysis channels instead of a fixed harmonic filter bank as used in previous FFT-based vocoders. This is the original full version from which the Technical Report (CCRMA STAN-M-43) and conference paper (ICMC-87) were prepared. Additionally, minor corrections are included, and a few pointers to more recent work have been added. Work supported in part by Dynacord, Inc., 1985
