How to use a microphone to record / stream audio real time?


#1

I have been thinking of developing a birdhouse with a built in camera and microphone so I can watch and listen to the birds living in there in real time. I have a Fez Spider and a WIfi module. I also see some camera modules, so the only thing left is recording the audio. I noticed a Music module: https://www.ghielectronics.com/catalog/product/317

However, it says “mportant Note: The RCA connector marked “MIC” does not work with microphones. It is a regular Audio in connector.” - so what exactly does this mean? Is it possible to make this work with a microphone? I’m sure I’m not the first guy to need a way to capture audio, please share how with the Gadgeteer platform.

Thanks, Paul

@ andre.m - when I say real time, I mean like sub second latency. Like I literally want to stream the video and audio over my wifi connection to a server that will record it and make it accessible (via streaming) in the browser, etc.

Maybe you could “stream” audio, assuming you could get your mic connected (I doubt it, really), but you’re not going to be “streaming” anything like video, not with a G400, let alone a Spider. You’re looking at a single frame per several seconds, and that’s without sending anything out over WiFi.

Your best bet in this arena would be a micro with a DCMI interface, and some awfully good native programming knowledge. Then, maybe. Maybe.

Google “WiFi camera”, and see what you come up with.
