how does NX generate noise?

in most computer functions, "Noise" refers to a stream of numbers with no discernible pattern, however certain sound synthesizers can generate noise where there is a clear pattern which is percieved as pitch. how is this possible?

It’s more like a cut-off for higher frequencies.

Technically the sound generator creates random numbers. At lower frequencies it simply generates new numbers less often, so in the stream numbers are repeated.

is there a way to reset the RNG for noise?

No. If you have the idea of using this to output custom waveforms, it wouldn’t work anyway, because code can update audio (and video) only 60 times per second. It’s not enough for waveforms.
