Now I just need a way to display the output. What better way than using 2 LED Matrix Links?! You find them in our Tindie shop and they make it really easy to drive 8x8 LED Matrix displays. The kit comes with everything you need, just add your Arduino\Compatible micro and you are ready to go.
After an evening of coding I came up with a way to display the Left and Right channels, one per display. I started with the example from this site: http://tronixstuff.wordpress.com/2013/01/31/tutorial-arduino-and-the-msgeq7-spectrum-analyzer/ and I was then able to code the rest to take the analog data and display it.
Here is a quick video on how it turned out.
The only thing left is to have the option of transposing it so it displays horizontally. This still needs to be done using the setRow function. If you use the setColumn otherwise, it will update too slow.
