I am looking for fast fourier transform on streaming audio input (analog). Can the audio shield do this and do I need to wire in an input to specific pads?
Turn to page 24 for the part about using FFT. Maybe first read pages 8-11 for background intro to the design tool.
There's also a full walkthrough video, if you'd prefer to watch a demo rather than read the printed material. Click the link through to youtube and expand the description for a links to the time index in the video where each part (corresponding to the written PDF) begins.
