Interesting if that is considered to be copyrightable. Any white noise track is perceptually indistinguishable from another, but none have the exact same sequence of samples except by chance, or if the noise generator happens to be deterministic as a function of time.

I find it so odd that people then to streaming services for stuff like this. I have a dedicated white noise machine, and when I travel, I use the white noise (bright noise actually) built into the iPhone.

Relying on an external hosted service would never cross my mind, and surely wouldn’t be something I go to on a daily basis.
