QSO online 'Alert OVER IP' sYsTEM - AUDIO FREQUENCY to SPECTRUM readout with TEXT OVERLAY

USES GSTREAMER script for both the SENDER and RECEIVER SEND 4Khz, 12Khz OR 20Khz to RX OP

here is the example using 4Khz

gst-launch-1.0 -v audiotestsrc freq=4000 ! audioconvert ! opusenc ! rtpopuspay ! udpsink host=(ip address of the RX OP) port=9999

RECEIVE OP script: gst-launch-1.0 -v udpsrc port=9999 ! "application/x-rtp, media=(string)audio, clock-rate=(int)48000, encoding-name=(string)OPUS, sprop-maxcapturerate=(string)48000, sprop-stereo=(string)0, payload=(int)96, encoding-params=(string)2" ! rtpjitterbuffer ! rtpopusdepay ! opusdec ! audioconvert ! audioresample ! spectrascope ! textoverlay text=" QRT QRX QRV" valignment=top halignment=left font-desc="Sans, 24" ! ximagesink sync=false sync=false async=false

NOTE: the spacing between the TEXT QRT, QRX & QRV was dialed in by testing and running... for a 1920 horizontal monitor
