So based in @rbj answer, can i try to show you visually ... Take a look in this pure tone signal, one sine at 100hz and sample rate at 44100hz. just by looking you can find where the pattern starts to repeat itself, I marked it with the naked eye as being in position 441(Period) So we take exactly 100hz --> 44100/441=100hz Another example: Another 100hz ...

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() ...
