原创 DIY audio spectrum analyser for BADASS display

Well, I'm pleased to say that things are bouncing along with regard to my Bodacious Acoustic Diagnostic Astoundingly Superior Spectromatic (BADASS) display project. As I discussed in this blog, the plan for my first-pass incarnation of this project is to use an Arduino Mega microcontroller platform to drive the display itself. One reason for this is that I'm using Adafruit's NeoPixel strips, and the folks at Adafruit provide a really nice NeoPixel software library for use the Arduino Uno and Mega. Meanwhile, a second device -- either a microcontroller or an FPGA -- is to be used to perform the digital signal processing (DSP) on the incoming audio stream to extract the spectrum data.
