brief demo showing the use of 1 single Gstreamer script, to take the wasapi LINE INPUT of the WINDOWS 10 pc, where a harsh square wave CW KEYER's output is waiting to be transmitted to mumble input...however, it is first diverted to this Gstreamer script, and bandpass filtered into a nice sounding sine wave with shaped edges...and then routed to both the users PC hardware sound card for sidetone monitoring...and also to a wasapi virtual sound card which is the same virtual sound card that mumble is listening to...
here is the video...please view the video description for further info
