About White Noise Sounds - Nap Noise
Nap Noise plays white noise and relaxing scenes, with a Sound Lab for mixing ambient sounds and an AI Creator that makes scenes and sounds on request. Hugo Pinon sent it to FoldHunt with its iPhone Duo version ready for launch day. In Hugo’s video on the iPhone Duo simulator, the cover shows the scene in a round window above the mixer. Open flat, the controls move into a left-hand column and the video scene fills the space beside them, or the whole screen.
