Hello, I'm trying to add a wireless push-to-talk microphone to a retail store stereo sound system, ideally, when the microphone is activated, it would broadcast on the store speakers and cut the other audio streams.
I'm thinking of using two ESP32 to transmit the sound and a simple ON/OFF signal over wifi on the current store network. I also need to find a way to have an electronically controlled stereo switch (controlled by the ON/OFF signal).
I know there are existing resources on how to use an ESP32 to transmit audio, so I'm going to look into this, but I'm certainly going back here to ask for help. Some simple researches didn't find anything about an electronically controlled audio switch, if anyone has some clues, it could be of big help ^^
I made two simple schematics to try and make the idea clearer ^^
Thank you very much
