Could you build this?
No It relies on reverse-engineered low-level undocumented registers inside the ESP32 Wi-Fi PHY/modem hardware to capture raw IQ samples.
What it would actually take: Developing this requires deep digital signal processing (DSP) and RF reverse engineering expertise. It involves reverse-engineering proprietary Cadence/Xtensa baseband registers on ESP32 silicon, writing low-level C firmware to manage SRAM ring buffers at hardware sampling rates, and streaming raw IQ data via Web Serial/WebAssembly to browser-based FFT waterfalls.

Same idea, different domain
Nobody's really built a observability & eval tool for Media & entertainment yet.
