FM transmission test with FL2000

My USB 3.0 to VGA adapter arrived a few days ago so I tested the FM transmission example.

I used my own command for file playing:

$ ffmpeg -re -i sample.mp3 -c:v none -f wav - | pv -B 256k | sox -t raw -r 44100 -e signed-integer -L -b 16 -c 2 - -c 1 -e signed-integer -b 16 -t raw - biquad 4.76963 -2.98129 0 1 0.78833 0 sinc -15k loudness 5 | ./osmo-fl2k/build/src/fl2k_fm - -s 130e6 -c 350e5 -i 44100

Results here:

And it really works! 🙂
