Building an Active Noise Cancellation System on ESP32 (Part 2): The Wiring Problem I Didn’t Expect
Spent hours debugging my ANC algorithm on ESP32🎧
Turns out one of the biggest improvements came from twisting a pair of microphone wires🔀
The FxLMS filter still isn’t converging, but at least now I’m debugging the algorithm instead of the wiring.
Real engineering starts at the physical layer💪🔥
