Looking for any tips, existing walkthroughs, youtube video, other message forums on transferring audio from one device to another.
i've google-fu'ed and can't seem to find what i'm looking for.
I want to build my own battery powered surround bookshelf speakers and i'm looking for a way to transfer RCA output from the receiver to the speaker.
Looking for what Arduino, esp32, esp8266, etc... that I can use to accomplish this. Think it could be done over wifi or Bluetooth.
Each speaker would need a single channel of audio. Looking to start with 2 speakers then maybe up to 4, but i'm fine if each speaker needs to have it's own pair of devices.
