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

YouTube compression will remove inaudible sound ranges anyway, so they probably had to fake something for it to make a sound at all.

As residentoflaniakea@discuss.tchncs.de pointed out, its 98hz. Still low, but not 0.33hz.
