Audio Shield Input

[mkomkom]

Hi,

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?

Thanks,

Yes.

For a quick intro, check out the audio tutorial.

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.

Ah I think I see it now, my apologies. I just need to solder a jack to the 4 input pads?

Very cool board you have made here. I might pick up a second set for my daughter to mess around with!
