I have only just discovered this interesting SoC and an initial fun project comes to mind for a wifi baby monitor like so:

Condenser Mic -> A/D Input -> ESP-12 ::::Packetized Audio::::> Phone or PC app.

There's also "sound sensor microphone modules" for about $4 with a digital output stream if the onboard ADC is not suitable (or available) for some reason.

Has anyone already worked on anything similar (especially for the audio processing) or do I need to start from scratch?

I have done some basic scouting around on these topics and I'm off to do some more looking, but if anyone has any insight that would be great.

Thanks

I'll keep an eye on this thread!

Built-in ADC might be too slow for this purpose. Also WIFI activity will interrupt the sampling periodically?
