What kind of latency would I get streaming between esp32-LYRAT boards

[Jimrux]

I am considering using an ESP32 LyraT board to stream audio to many ESP32LyraT receivers (approx. 50) is this possible using the ADF. I have done some tests using an icecast server streaming to an ESP32 internal DAC using the ESP8266Audio libraryhttps://github.com/earlephilhower/ESP8266Audio and am getting 3 to 4 seconds latency. Would this be improved using the ADF? Is there a better way to do this than using http streaming? I only need approx. 20 to 2000 Hz frequency bandwidth.
Thanks for any suggestions.
