Off-Loading the Voxengo Spectrum Analyzer VST plugin to a 2nd computer - using a Gstreamer PipeLine
using Gstreamer TCP AUDIO server/client pipelines to send & receive audio for spectrum analyzation from 1 PC to another PC - to keep the CPU STRAIN off the 1st PC from being taxed by the SPECTRUM ANALYZER VST PLUGIN
in this example, the 1st PC is a Raspberry PI 2 b
and in trying to analyze a MORSE CODE AUDIO BANDPASS FILTER running on the PIE... -taking the high pass/low pass filters IN and OUT and watching the VOXENGO SPAN VST PLUGIN SPECTRUM ANALYZER on a 2nd PC - a Windows 10 LAPTOP to view the results of the filtering audio spectrum
the Raspberry pi sets up a TCP AUDIO SERVER...so any other PC's may connect to it and receive the PI's audio...
the TCP AUDIO SERVER script used on the pi in this example is:
pi@raspberrypi ~ $ gst-launch-1.0 jackaudiosrc ! "audio/x-raw,rate=48000,channels=1,depth=24,width=24" ! audioconvert ! rtpL24pay ! rtpstreampay ! tcpserversink host=192.168.1.130 port=5678
on the WINDOWS 10 Laptop to the TCP CLIENT script used was this:
C:\gstreamer\1.0\x86_64\bin
gst-launch-1.0.exe tcpclientsrc port=5678 host=192.168.1.130 do-timestamp=true ! "application/x-rtp-stream,media=audio,clock-rate=48000,channels=1,encoding-name=L24" ! rtpstreamdepay ! rtpjitterbuffer latency=128 ! rtpL24depay ! audioconvert ! wasapisink buffer-time=128000
on the windows 10 laptop, JACKROUTER was used for the audio engine, and CARLA was the vst host for the SPAN VST PLUGIN

the "JACK" driver on Carla was used since the Jack Audio Connection Kit forWwindows was operating as the Windows 10 audio engine...
