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

hi, most people can hear as low as 20hz most big speakers can produce sounds in the 30-50 hz range. smaller speakers can usually only produce higher frequencies. it's different with headphones, but you can check the specs for your hardware online, mostly from the manufacturer or testing sites.

This sound can be heard from my smartphone speaker, which definitely can't play low sub bass frequencies. and it sounds pretty high as well. maybe 100hz or something? can't say for sure. can't check on my PC right now, might come back to it later.

-edit- try this site for tone generation: https://www.szynalski.com/tone-generator/ it should help understand the sounds of frequencies a little better!
