White Noise & Co.: Frequency Shaped Colored Noise Generator

Very cool thing I just found while thinking about getting a white noise generator to flatten out the road noise in the new apartment.
good one, I'm running it now, it's almost the same as playing some rain music over YT
neat. I usually use an alexa skill "alexa open thunderstorm sounds" and that treats me pretty well the nights I need it. :)
