Ambient Noise (ANoise) Player Fixed For Ubuntu 16.04 And Newer
Ambient Noise, or ANoise is a simple, lightweight application for playing ambient noises, such as waves, rain, fire, and so on, useful to help you stay focused and boost productivity, or fall asleep.
The application didn't work in Ubuntu 16.04 and newer until recently, when it was updated to GStreamer 1.0 and Python 3, along with some bug fixes.
