You can buy perfectly loopable white noise tracks on iTunes for $0.99. Permanently yours. Don’t need internet. Looping feature built in into the music app. As a bonus I have a Shortcuts home icon that plays it in a loop and sets focus mode to sleep.
Really? You can't spend 5 minutes to look up software that will generate many different types of noise, perhaps even tuned for the use case? And why the resentment for free software? You are gonna have an easier time finding that kind of stuff as a simple webpage or better yet on f-droid rather then on an ad infested, corpo boot licker laden platforms like google play and the app store. Just the fact you don't have to sweep trough heaps and heaps of garbage is a plus. Sure normies are gonna prefer paying for an mp3 or whatever, but we are on hacker news, we should strive for better. (and maybe help enlighten our fellow clueless users...)
because piping dev/urandom into my speakers wont be pleasant background noise it will have some horrible high-pitch noise i last heard when i used dial-up and i don't want to hear that again. so i would have to mess with it and waste time making script to sculpt the random sound wave to not be to low pitch or to high pitch or to quiet or loud and by the time i have something usable i have spent more time playing with bash, and looking at pulse-audio man files than I really want.
You've overlooked that "white noise" here is a colloquial term referring not only to what you've described, but also to recorded sounds of water, wind, loud cafes, ambient drones, and more.
Is it technically accurate? No, but most people's feathers aren't ruffled by it.
And I have a shortcut that turns on the white noise apple includes on the iPhone for free. No internet, no tracking, no money, and no cluttering music app with white noise track
