> It would also be great to have this running on ESP32 or similar

ESP32 has its own port of the Codec2 library, which allows intelligible communications using very low bandwidth (a few kb/s). It could make the ideal solution for creating small cheap intercoms scattered around a small area using WiFi, or employing very low bandwidth radio connection such as LoRa for wider coverage. I still didn't see any real application, beside a few simple proof of concept videos on YouTube, though.
