I have a program that broadcasts and FM radio signal, and there is an option using this command to allow direct audio streaming:
arecord -D hw:1,0 -c1 -d 0 -r 22050 -f S16_LE | sudo ./fm_transmitter -f 100.6 -
I have a Raspberry Pi Zero W that is connected to my Windows 10 Computer through SSH. I, unfortunately, do not have a USB microphone. Though I was curious if it's possible to use my phone with an app similar to WO Mic? Connecting my phone either wirelessly or via USB would both be acceptable, but I am not quite sure how I would go about doing this.
