In previous Ubuntu version, just open a shell and run

sudo add-apt-repository ppa:costales/anoise
sudo apt-get update
sudo apt-get install anoise

Fixing Ambient Noise for Ubuntu 16.10 require for now to compile from source the application. Run these commands into a shell, first installing dependencies:

sudo apt-get install bzr gir1.2-gstreamer-1.0 python-gst-1.0 gir1.2-gtk-3.0 python-distutils-extra gir1.2-webkit-3.0

The sound indicator:

bzr branch lp:anoise
cd anoise
sudo python setup.py install --prefix=/usr 

The sounds:

bzr branch lp:~costales/anoise/media cd media sudo python setup.py install --prefix=/usr 

If you have a player in the sound indicator, it's done! If not, install the GUI:

bzr branch lp:~costales/anoise/anoise-gui
cd anoise-gui 
sudo python setup.py install --prefix=/usr 

you can now run anoise form terminal

anoise &

or from menu
