For nearly eight years now, this coming through earbuds has been the only way I can sleep at night. Grateful customer of the iOS app.
Go to Settings > Accessibility > Audio/Visual > Background Sounds, then turn on Background Sounds.
Rain , Stream and Ocean are my favourite while needing to focus
If you're just looking for white/pink/brown noise, you could alternatively generate it using ffmpeg. I like ffmpeg -f lavfi -i anoisesrc=color=brown:amplitude=0.4 -filter "lowpass=f=400" -f pulse -device playback-device "noise" for example.
Thanks for the kind mention! I am Stephane, the person behind that website/project. I see a lot of people having concerns about the title - Background Sound Canceller - and they are right. That title is not mine, but poster's own. I describe my project as "Background Noise Generators", or sometimes as as "Non-Distracting Noises and Music". They are not sound cancellers but sound maskers . The idea is to create a nois…

On iOS you could also use the native built in background noise functionality which is good. Go to Settings > Accessibility > Audio/Visual > Background Sounds, then turn on Background Sounds. Rain , Stream and Ocean are my favourite while needing to focus

I don't think it can be done.. active noise cancellation needs to be really really fast and is done using dedicated hardware afaik.
I suspect it could be done for sort of periodic noise (or possibly with a predictive net). I've always wanted to implement this on the web but never got around to it.
And the most annoying noises tend to be periodic anyway.
I think you should give it a try... let us test it, if you can cancel out my air conditioner noise you'll be my favorite person...
Is there any app that uses scripts to generate this sort of audio? I’d like to be able to download a script of a thunderstorm, that sounds different every play, or the script for a coffee shop complete with the lunch rush and afternoon lull.
I created a FOSS alternative (that's not nearly as feature complete as mynoise.net) [0] but it has the benefit of being CC0 licensed including all of the samples.
If you have features that you think would enhance the experience, please feel free to open an issue [1] or DM me.

Thank you for the app! I use it every single night to drown out the POS bird that screams outside of my window as I’m trying to sleep.

How fast can it need to be? The output frequency would be below 20kHz so latency of 50us or so, probably too fast for a userland app but I'd expect it to be doable in a driver or in the OS?
I think you have to detect the sound with a microphone, then come up with the canceling waveform before the sound hits your headphone drivers (as they will be generating the canceling waveform). Given the typical size of headphones, it would be something like
2cm/(34300cm/s) ~ 60us
Although, sound travels faster through solids, so might want to be a little quicker. And 2cm thick headphones would be pretty thick.
So basically this is for people who bought and use noise cancelling headphones and want to put back noise in their life. What about...removing said headphones and listening to the life around you? And even better, open the window?
Noise cancelling headphones still have a residual noise, that you will hear, because our hearing has an incredible dynamic range. Adding a faint background noise of your choice, to cover that residual noise, is a good idea. Then, these crafted noises do exist because of the exact nature of the life around you. For many people, the "life around you" is what they want to escape, exactly.
