Music Visualization

Fri Sep 28, 2012 7:48 am

This is my First post, but I have been mucking around with my Raspberry Pi for what seems like ages now.

Last week I managed to use the GPIO's to run a small LED Matrix(http://www.youtube.com/watch?v=BHzUf8gyWK0). So now I want to use this matrix to display a Visualization of whatever music is playing on the RPi at the time. It would be really cool if I could somehow sample exactly what was coming out of the raspberry pi and just display a visulaization of what is playing.

Like this

I would prefer to do this in Python, but my mind tells me that if I can somehow "sample" the audio that is coming out and process it fairly quickly I may need something lower level. Any help or pointing in the right direction is appreciated.

Nope, sorry never got around to it. But I did read up on one that Adafruit did on an Arduino, visualizing a microphone input. I would recommend having a read up on Fast Fourier Transformations.

The reason I never went ahead with it is I couldn't be bothered.
