Pitch synchronous overlap and add
WebbEEE 13. A method according to any one of EEEs 7-12, wherein upon determining that the audio corresponds to both dialogue and music, the audio time stretching algorithm of the media content is set to a Time-domain pitch-synchronous overlap-and-add, TD-PSOLA, algorithm, or a Pointer Interval Controlled Overlap and Add, PICOLA, algorithm. EEE 14. WebbWe're now going to combine that idea with the overlap-add technique for concatenating waveforms to create a general method, called TD-PSOLA, which can modify F0 and duration of recorded speech. The Time-Domain Pitch-Synchronous Overlap-and-Add algorithm operates in the time domain: on waveforms.

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. ACKNOWLEDGMENTS Webbtermed depitch that attempts to remove pitch information from the speech signal by forcing every speech frame to be pitch synchronous and include a single pitch cycle. This paper presents a modification of the depitch algorithm, termed syncpitch, that performs pseudo pitch synchronous processing while still preserving the pitch information. The new

In the PSOLA method … Webbchosen for this project is the Time-Domain Pitch Synchronous Overlap and Add method(TD-PSOLA). The benefit of this algorithm is that it is simple and one of the fastest imple-mentation for pitch correction. A. TD-PSOLA The …
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.

We choose TD-PSOLA over the WORLD [9] vocoder due to its superior naturalness and pitch-shifting [19]. TD-PSOLA works by pitch-tracking the speech to determine locations (pitch epochs) to split the signal into chunks corre-sponding to one period.
