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
Ohhh now that one is interesting. I actually can hear it set to 1hz, but its not 1hz that I am hearing. Rather a higher pitched whine that cycles at 1hz. Similar happens for other very low frequencies and changes the frequency of the whine. I presume it is my speakers struggling with playing very low frequencies.
Along with adjusting volume, every low frequency can be heard but it moves from hearing an actual low frequency to hearing the speakers movements and then really low it whines.
Are you perhaps hearing a 50/60hz signal from your electrical grid? If its higher, could possibly be frequency from your processor (or some other internal device) clock?
Those frequencies are well outside the usual working range of most amps and speakers, so its not surprising they dont work very well.
Clock speed of some kind of internal component perhaps, would be interesting if I had a way to measure it.
