Join Mark as he builds a digital vocoder using a Teensy 4.0 and audio shield, demonstrating how audio spectrum data can be analyzed and used to reconstruct sound in real time. He walks through the full hardware setup, from soldering components on a prototyping board to wiring potentiometers and audio jacks, then dives into the software using the Teensy Audio System Design Tool. The result is a working vocoder capable of producing classic sci-fi effects like the Cylons from Battlestar Galactica: bit.ly/41uZUGb
