I would like to be able to send audio over WiFi. Our little kid has recently moved into his own room which is at the other end our house (we have a longish house). He has some bio-med challenges so we just need to keep an eye on him specially at night if he wakes up. Baby monitors don't work very well - keep dropping signal.
I was hoping to use arduino to be able to transmit audio from our boy's room, over wifi. And we use another arduino to receive the audio,
I came across a post that uses ESP32 to send audio wirelessly using the ESP now protocol. The OP was also creating a baby monitor. I adapted this to create an intercom system and was quite happy with the results. It comfortably reached 16 KHz without dropping any packets.
the problem is that if your baby monitor is dropping signal then I would imagine the ESP32 will also drop signal. Its range really depends on your environment (more than 10 metres is tough in a noisy environment). You could create a chain of ESP32s throughout your house but this might be overkill. Some ESP32s also allow you to attach a better antenna which may also help.

Newish to Arduino, so apologies if I sound dumb.
Don't worry about that. Learning this stuff should be fun and the forum should be welcoming!
Thanks bud. Really appreciate the pointers. Will have a look.
From my brief reading, ESP32 support WiFi. If I can get them to use my wifi lan, that should solve the issue with range. The construction & design of our houses causes the traditional baby monitors not to work properly. In fact, I had to get two WiFi A/Ps to get half decent wireless coverage!
