Iroh works on most esp32. Here is a mixed bag of examples for various esp32 variants.

Most examples that I did so far were about simple sensors, but audio streaming should work as well. If you need high bandwidth you might want to look into using the esp32 built in crypto hardware acceleration though.

Although audio is probably fine, but if you want to do video via an esp32 you will need the hardware crypto.
