There is no such thing as a Stupid Question!

Don't be embarrassed of your curiosity; everyone has questions that they may feel uncomfortable asking certain people, so this place gives you a nice area not to be judged about asking it. Everyone here is willing to help.

ex. How do I change oil

How do those videos of pure tones in the sub 1Hz or in general any Hz tones produce that tone for the video? (sopuli.xyz)

I want to be able to do that too, like this one for instance

PURE 0.33 Hz EPSILON BINAURAL BEATS | Epsilon Waves | Reality Shifting ⚡️

It would be great to be able to produce any arbitrary Hz pure tone or whatever that example is

Like 0.165Hz or anything

wav_fc = numpy.sin(2 pi fc t)

fc is the frequency of interest, and t is the time series sampled at 1/fs where fs in the sampling rate. So if you wanted a 48khz sampling rate, t would be something like numpy.linspace(0,1,48000)
