The Coolmic[2] app is particularly interesting because it can turn a
Android phone (e.g. SmartLav+ lapel mic[3]) into a wearable mic for

Not everybody is keen to run Icecast though, some people may want to
mix-and-match the Icecast source clients like that with some other
broadcasting platform, Jitsi Meet[4], Zoom or whatever.

a source in PulseAudio so that any arbitrary application can use the
sound feed as if it was a local microphone?  For example, has anybody
tried to do this with PulseAudio module-pipe-source[5] or

We can already do stuff like this with video, for example, using the
v4l2loopback kernel module with gstreamer.  I provided a very trivial[7]
script for that and it would be interesting to have a parallel example
for audio.
