So I'm working with the WS2801 LED Strip and I want to make a VU meter with it. The only problem is that I cant read out the soundoutput of the pi without crashing or influencing the soundserver. Is there a good way to constantly read the magnitude of music? I would be glad, if I could finally solve this issue.
Thanks :)

After hours of working, the SDL Sound API and help from this website ... urier.html helped me solve this issue.

Although I think it's for a different RGB LED protocol the PiMoroni VU meter example code for their Blinkt! may help.
