This is the benefit of a pahse vocoder. A phase vocoder is an algorithm for speeding up or slowing down audio without changing the pitch. So if we can scale the time of the signal while leave the pitch unchanged, we can get a pitch shifted version of the Project Motivation. Algorithms like the Phase Vocoder require a buffer with a fixed size, consistent between calls, and usually work best with a power of 2 because of the FFT algorithms they use (although these days the FFT is performant in many more cases than just lengths of powers of 2).

Our plug-in implements real time pitch shifting to an audio input and mixes the result with the original sound. Then, F is dilated along the Time direction by F(d Time, Frequency, Oscillations), and its complex phases are modified, to obtain a dilated version H of F (see the paper for more details). The Phase Vocoder can modify the speed of sound without changing the pitch. What if, instead, we could use some signal manipulation tricks to speed up or slow down a track without changing its pitch? It turns out we can, by means of an algorithm known as the phase vocoder. It appears to essentially work, but it is very immature. Stereo files: PV.
