I’ve wanted to try this for some time and am happy to collaborate here. For starters, let’s assume we’re working with the Game Frame V2 (2016 version) and I’d also suggest upgrading the microcontroller to a Teensy 3.2 for more Flash and gain access to the Teensy audio library. I’m traveling right now, but in a week I can verify there’s enough SRAM to compile on Teensy 3.2 w/ the audio library.
I’ve posted the new Game Frame source on GitHub if anyone wants to get a jump on it.

There is a FFT library for Teensy LC (converts microphone signals to frequency values) if you want to hack…
