The pitch period of a perfectly periodic function, $x(t)$, is the smallest positive value $P>0$ such that $$ x(t+P) = x(t) \qquad \forall t \in \mathbb{R} $$ Now, simply because a function is periodic with period $P$, then it is also periodic with periods $2P$ or $3P$ or $4P$ or any integer multiple of $P$, but we don't pick $2P$ or $3P$ or $4P$ for the ...

I wrote this code in python, it’s not yet optimized but still it worked perfectly for me from pydub import AudioSegment from pydub.utils import mediainfo in_wav = "input.wav" out_wav = "output file" with contextlib.closing(wave.open(in_wav,'r')) as f: frames = f.getnframes() rate = f.getframerate() ...
