In the case above, having FFT framesizes of 512 and 1024, we can calculate accurate bin values for “every other” FFT frequency row in the second FFT, by using your gAnaMagn[] gAnaFreq[] arrays and their respective calculations for phase and magnitude in the new bins of the second FFT (the ones that share the same frequency as those of the first FFT). tmp = phase – gLastPhase[k]; After reading many material about DSP and Speech Processing. Tried the link from the previous post, but it no longer works. vowels and sibilancies, for independent processing.The channel vocoder can not be successfully applied to the time/pitch scaling problem, in the musical context it mainly is a device for analyzing and imposing formant frequencies from one sound on another. and what would be the best quality ? What is your fundamental question? This can throw off the precise timing of notes, and may remove few-millisecond-sized (but interesting) sound features due to deletion. something other than 2, 4, .5, .25, …) and I am interpolating in the spectra to accomplish this. I guess I do not really undestand what pitch shifting is…. can someone explain to me what beat markers mean in pitch shifting ? I don’t know why this link didn’t make it on our news page, it must have been lost during the site redesign. The (pre)smearing behaviour of the Phase Vocoder will be more disturbing in this case, since it occurs before the transient sounds and will easily be recognized by the listener. the more they overlap, the better we will be able to determine our true sinusoid frequencies in our measured signal. rev 2020.11.10.37982, The best answers are voted up and rise to the top, Music: Practice & Theory Stack Exchange works best with JavaScript enabled, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site, Learn more about Stack Overflow the company, Learn more about hiring developers or posting ads with us.

The more off-center it is in frequency from the bin frequency, the larger this phase offset will be. If your goal is to alter the pitch, not the timebase, bear in mind that when upscaling the pitch, echoes and the repetituous behaviour of TDHS are less obvious since the pitch change moves adjacent peaks (echoes) closer to each other in time, thus masking them to the ear. The sines and cosines used in the Phase Vocoder have no localization in the Time Domain, which without further treatment contributes to the inherent signal smearing. Principally, this is dependent on the constraints imposed on the actual task, which may be one of the following: Speed.
