AES67 Audio-over-IP on the ESP32-P4 (opens in new tab)

AES67/RAVENNA is the audio transport behind a lot of broadcast and live-sound infrastructure, and it normally runs on dedicated silicon or Linux boxes. This article is about getting a working, PTP-synchronized AES67 endpoint onto an ESP32-P4 — how the clock sync, the low-latency receive path, and the I2S playout fit together, what the measured latency is, and where the edges are.
