The following is the link to the mic I ordered:

I have no idea if the quality is great or not, it hasn't even been shipped yet and it's been 3 days so I'm starting to become a little skeptic here. In any case, I only saw your response (about the aliexpress one your received) only after buying it myself, it might be of equivalent quality.
I meant in the Direction from the client (desktop UI application) to the server where the raspberry runs node-red. I think I should expand your example and add an audio node after your recorder node:
This would take the mp3 samples collected by the recorder node on the client device (mobile or desktop) decompress the mp3 into WAV and shot it to the raspberry pi speaker. But I was just curious to how exactly does node-red server make the disctinction between (the speaker on the client side and the speaker on the server side(itself) )?
thanks I'll try that out, I originally installed it as described on your GitHub page: npm install node-red-contrib-ui-media-source@1.0.0-beta.1
The OFF is simply the snapshot state i took it in, but yes I did turn the switch ON lol! But good remark... you never know 
In any case, my test consisted of speaking through my laptop camera speaker on the client side... (but this is where I think the recorder did not sample from that speaker) to the server side, where I had my raspberry connected through HDMI to the TV. I expected sound to come out of the TV. But I see now that there are 2 issues.
1- I should wait for my usb speaker to arrive from china and talk into it (on the client side) and find out if the debugger at least can output some messages while I talk.
2- Next I should find a way to decompress the mp3 stream and output it to the server speaker (HDMI or USB.. to be seen).
Will be testing some more when I get free time.
Once more... Thanks for everything Bart.
