Wow, really cool app. It really reminded me of how much I miss the sound of rain and wind.

First of all -- awesome concept and execution, and great sound samples. Well-done.

But... not working on my 4S/iOS6. :(

Anyone got it working to play in the background, even when your phone's screen is off? I also wonder about battery life as HTML5 audio, vs if it were an app.

The creators clearly want to support HTML-only, according to the FAQ, but this calls for an app if anything ever did -- you want it to run, providing sound in the background, while you do other stuff (whether on or off your phone).

Interesting idea and cool presentation, I like the sliders and that I can play around with it. I will probably use this at work. edit: This is really good, I just accidentally left it on and had completely forgotten I was listening to the same thing. Very much works as advertised.

Agreed - not only is this cool, but the audio samples are pretty high quality. Great example of HTML5, too. A few years ago, this would have required Flash ;-)

I think you could have hacked it together with bgsound before HTML5, but it would be less reliable.

These types of sounds are absolutely wonderful for soothing angry babies!

I wrote an Android app based on a similar concept, although it uses a PRNG and Fourier transform, with no recorded samples:

Someone posted ambient warp-core sound from Star Trek on Reddit earlier today, maybe you could add this.

Yeah, very cool. Saves people money as well (up to $200): http://www.sharperimage.com/si/view/product/Sound-Soother-Wh...

You could stream example outputs 24/7 as net radio channels so they are also available on other devices / STBs (Roku) / Consoles / Smart TVs etc..

Heh, thought it was CSS-based website background noise texture generator…
