My new app is Ambient Noise Player. It's integrated in Ubuntu with this pre-installed noises:
Coffee Shop | Fire | Forest | Night | Rain | Sea | Storm | Wind
ANoise Player
How to install?
Run these commands into a shell:
sudo add-apt-repository ppa:costales/anoise
sudo apt-get update
sudo apt-get install anoise
```Then search _Ambient Noise_ in your launcher just this first time.
The next times, control it from the sound indicator :)
You can install more user's noises too with this command:
sudo apt-get install anoise-community-extension1
(Need restart session)
[Bug #1440061](https://bugs.launchpad.net/ubuntu/+source/indicator-sound/+bug/1440061) in the release: All work fine, but the entry in sound indicator is grey in Unity. Any help about this is really welcome.
