Multispeaker audio streaming system

[ciko2k]

Hello everyone,
I'd like to create a real-time, synchronized streaming system between multiple speakers.

The idea is to have an ESP32 connected to an audio source, acting as a transmitter, capable of sampling and sending the signal to multiple ESP32 receivers, to create an audio streaming system.

Can you tell me which libraries, examples, to use and how to implement them?

Thanks everyone.

Please note that the networking speed and thruput of the ESP32 is quite limited: you might need to minimize the amout of data that is distributed. I see the following alternatives

• Using UDP broadcast
• Using ESP-Now
• Using SnapCast (e.g. on a RasperryPI) and snapclient on the ESP32 receiver

You can find the examples in examples-communication directory!
