How do I make a sound graph

hello there is there any way to make a sound graph out of the music, playing in game?

something like that http_:_//hsto.org/storage/3811ce38/b2b2c125/5da0b7fe/3ff9bb98.png

Hmmm. I don't have C2 with me right now, but if there's a way to check the sound's loudness, you could constantly spawn sprites and set their height depending on the volume. Make them single-colored and spawn them tight enough to make them look like the graph in your picture. The list of expressions here might help you: https://www.scirra.com/manual/109/audio

thanks it works

Nice, is it possible to post a capx or see it in an online demo?

ok. i'll post it a bit later

here you go. but the only thing is, when the sound is loud, the graph is in lowest scale. that is because loudest point is 0 and quietest is negative. and i can't figure out what formula converts it))))
