Pitch synchronous overlap and add
Did you know?
Webb3.1 Pitch Synchronous Overlap-Add (PSOLA) It is an analysis-synthesis method where the speech signal is decomposed into a number of pitch-synchronous short-term waveforms. These short term signals can be altered either in the time domain or spectral domain to obtain multiple synthetic short-term signals.

WebbThen overlap and add them. Apply that fade out and fade in: that just scales down the amplitude to zero, smoothly. I overlap them, and where the samples overlap, I'll sum them, I'll add them together. Hence the name of the method: 'overlap-add'. Here are the waveforms concatenated using overlap-add. Now the join is quite hard to spot. Webb24 aug. 2024 · For speech, Time-Domain Pitch-Synchronous Overlap and Add (TD-PSOLA) algorithms work better, with PICOLA being the most-used one (via sonic, which is what YouTube uses). Better still is ESOLA (Epoch-Synchronous Overlap and Add), which according to it's introductory study is both significantly faster and better than TD-PSOLA, …
Webb8 nov. 2012 · During the synthesis stage, the sound samples corresponding to the target engine speed evolution are concatenated with an overlap and add algorithm. It is shown that this method produces high quality audio restitution with a low computational load. It is therefore well suited for real time applications.
