How to connect a microphone with a 3.5mm plug via a Wi-Fi transmitter? (Need something like Wi-Fi adapter for audio cable)?

Question

WiFi

There is a building with a voice announcement system, which is conducted using a microphone connected via a 3.5 mm jack. It is necessary, without stretching the cable, to take this microphone to another room. The entire building is covered by Wi-Fi.

Are there receivers/transmitters that connect to the internet and to a 3.5mm jack so that you can broadcast audio over the internet like an IP camera? Figuratively speaking, turn on the "Internet extension cable".

Answer 1

The simplest and cheapest: a pair of ancient computers and an "Internet radio" stream between them.
More complex / better / cooler / more expensive - IP notification module. like snom pa1, and ip telephony
