Non-Stationary Analysis/Synthesis using Spectrum Peak Shape Distortion, Phase and Reassignement
Geoffroy G. Peeters, Xavier Rodet · 1999
A new Analysis/Synthesis method, named SINOLA, based on “sinusoidal additive ” and “OLA/PSOLA ” synthesis, is proposed. It allows high quality transformation of both stationnary and non-stationnary parts of a signal. Time-frequency characterization and synthesis parameters estimation is done by a novel method based on spectrum peak shape distortions and time-frequency phase evolutions.
