Welcome!
Well, it's not as ultimate as it could be but also it's not so bad so far.
ULTIMATE SOUND VISUALIZER 2,000,000
ยฎ uses JACK Audio Connection Kit as base sound system,
if you are using Ubuntu or another distribution with PulseAudio I have good news for you โ You even don't need to
download this piece of script on your computer. I made it for myself as my first attempt into Go
programming language.
Code uses xthexder's go-jack library/bindings for JACK Audio Connection Kit.
./jack-peak-meter -title
