YouTube user Chuck Swiger made this great project using a BeagleBone Black- so pretty!
Beaglebone black with ledscape displaying the Fournier transform of a Bach Invention (No 8 in FMajor) along with the music.
It’s actually a two pass operation – first time calculates the fft in numpy and stores the results, 2nd time plays the wav and shows the cached results in LEDScape. Code based on lightshowpi which uses the same strategy.
