BirdNet-Pi: streaming the microphone

This is about audio streaming from my system's mic.

I wanted to use AI to do all the thinking & lead me through the config.

But it didn't turn out to be so simple.

BirdBoxPiCam2014: Streaming video at 30fps

Now that the female has moved on from egg-laying-mode to incubation-mode, I've switched off motion detection in favour of live streaming.

It was more of a struggle than I'd expected to get streaming working, but I can now view the action live (well, live-ish if you ignore the 3 second delay) on one or more clients running VLC.

Video can be recorded on the server (i.e. the Raspberry Pi) or on a client.
