Follow this guide to get it to work

• replace scipy.fftpack with scipy.fft as this enables multiple cores to be used on the Raspberry Pi for overall speed improvements

Bill of Materials (in progress)

• 5V/12A PSU [~$17]
• 3.5mm Audio Stereo Y Splitter [~$8]
• USB stereo adapter [~$10]
• 74AHCT125 Quad Level-Shifter
  • Adafruit [$1.50 + shipping]
  • Amazon [~$5]
• Miscillaneous Jumper Cables
• Breadboard

So this comes out to be approximately $40 worth of items, considering you already have a breadboard and some cables to connect from the GPIO of the Raspberry Pi.

And of course a Raspberry Pi, do not buy at more then MSRP!

This has been tested on a 3B+, although anything onwards from the first generation should work just fine.
