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()
