[Lab] Audio Spectrum display

[Justin Slootsky]

I've been thinking about doing something like this, but a completely 
different display method (individually addressable pixels in a line,  
colour to denote frequency,  or if that just works out to too close to all 
white, then pixels for a frequency, and vary the intensity...  Or something)

The bit that I'm wondering / worried about is that I'm planning on using 
this in a very loud venue,  what microphone choices do I need to make in 
order for it not to be all blown out and reading 11 the whole time?
