There's a sneaky menu bar background noise app already built into MacOS. You can add "Hearing" to the menu bar (or control center) from settings, and then use that to enable "Background Sounds"

I really like this. I had a look through the source code as well and it's cool you shared it.

I generally listen to white noise when I am trying to concentrate, but its Dave Clarke's techno/electo podcast, "White Noise"! https://www.youtube.com/watch?v=36FkrrpzFOA

What's the deal with brown noise and dark noise etc? How does it help you? And how does it help you?

this is pretty cool. some of the lower frequencies make my ears feel weird. I wonder if this could be extended to do binaural beats

Ummmmm might want to rethink the naming ... South park defined the term brown noise as a sound designed to make you shit yourself ( this was over 2 decades ago BTW )
