Here’s another video of my setup using a teensy 3.1 and the new audio shield to control ws2812b pixel strips. i’ve now finished installing a bigger one in a local club so will hopefully grab a vid of that in action later this week.

Looks Great what are you putting the strips in?
Nice! I would be interested in your audio analysis code 
the strips are in aluminium u-channels with plastic diffuser covers
Cool thanks is that something you made yourself or something you bought?
