Non-Stationary Analysis/Synthesis using Spectrum Peak Shape Distortion, Phase and Reassignement
Résumé
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.
