I think two devices can record from the same mic can't they? (but not
video, though maybe that's possible now in windows 10 dunno otherwise
you could split it in show or like you were saying with pipes "maybe"

Dear All,

Is there any way - on Windows - to share a dshow USB microphone device to
provide the same audio stream to two different FFmpeg process/pipe "same
time"? Or this is not possible because of device exclusive usage by Windows
or like that?

Thanks!
Maybe not the best way, but you could produce a Multicast Stream:

ffmpeg -re -i 'audio.source' -acodec pcm_s16be -ac 2 -f rtp rtp://239.0.0.1:1234

And then you can use the stream several times. When you don't want to spam your network interface full with the multicast traffic, you can make a virtual "loopback" interface in Windows, and use this one.
