The lights are getting closer. There will actually be some 43 fps lights to look at soon. 

✅ i2s microphone
✅ circular audio buffer
✅ hanning window
✅ 4096 input fft
✅ a weighting
✅ bark scale (and others)
✅ calculate RMS
✅ full scale decibels
✅ scale to fit on the led matrix
🔲 wire up the led panel
🔲 double the frame rate and do dithering for handling dim leds
🔲 color gradients
🔲 more cool patterns
🔲 gps code
🔲 radio code
🔲 lots of soldering
