So here is a cool video the I stumbled across recently, made cooler by the fact it has links to some really useful places online, namely an Arduino forum with a post about FFT data driving LED colour spectrums.
Although I can already see this being to rapid changing for any sort of analytical use, it could be fun to include this as a setting on the arduino to get a bit more vibe going when you are just listening back to what you have created or other peoples work.
On the more analytical side, we can look at something like the setup in the video below, I am pretty sure this could be calibrated in order to use it as a VU meter and RMS meter. As the ideas keep coming the device I am envisioning is a modernise real time analyser, I will make sure to get my ideas down in a drawing soon.
This is neat because I could give the user control over certain parameters, enabling them to tailor their visual experience to the way they like it. The beauty of Arduino is they can be loaded with multiple libraries of code that can be cycled through very simply for different uses.
