NEW GUIDE: Trellis M4 Audio Filter Visualizer @adafruit @johnedgarpark #adafruit

We’ve got a new guide for you — The Trellis M4 Audio Filter Visualizer! Colored lights bouncing to the music and low pass/band pass filter effects are a must have for any party. Now you can bring the party to your Trellis M4 with the Audio Filter Visualizer!

With realtime Fast Fourier Transform (FFT) frequency analysis, the music coming into your Trellis M4’s STEMMA adapter is converted into colors and lights on the buttons.

Your music then passes through to the TRRS headphone jack on the Trellis M4 so you can listen to it. But that’s not all! We’ve also built in a low pass filter and band pass filter so you can trigger awesome sounding effects at the push of a button!
