A real-time noise generator to play "white noise" and help you block out distractions, find your focus, or just sleep and relax.
Noise Generator comes with white, pink, brown, grey, blue noise, plus some classic soundcapes, like ocean waves, rain, a humming fan, and many other nature and mechanical sounds.
Noise Generator doesn't play any sound file, all the audio is created in real-time using signal processing. This means no loops, true randomness, and a tiny app size.
A note on battery: Because the app calculates audio live, the more complex sound scenes may use a bit more battery than a simple MP3 player over the same time. However, for plain white noise, this app is highly efficient.
Noise Generator was made for my own use and now yours.
It's completely free, contains no ads, requires no internet connection, and has no in-app purchases - you're already premium user!
Now, let's make some noise!
