[Feature Request] let speaker output be an option

[mohad12211]

Feel free to close this if you consider it out of the scope of the project.

It would be nice to have the program listen to the current default speaker output and visualize it.
Not sure how the Raylib integration with it is gonna be (the callback).
Or how easy is it to make it cross-platform.

Cool idea! Place at as sort of screen-saver on second monitor :)
