• This project was just a experimental proof of concept, that you can do audio visualization on realtime.
• Usable on Windows and Linux, Mac untested
• This project is abandoned, I am programming a new, improved one.
• Source code is not readable

To start this application in Linux, use:

java -Dsun.java2d.opengl=True -jar ScopeLite.jar

Also you might want to change input from the:

pavucontrol

to put this application to read from monitor, instead from your microphone.
