QRQ CW filter for FLdigi's CW AUDIO OUTPUT by Gstreamer Script converted to an LV2 plugin by 'Carla'

[Chuck aa0hw]

KXstudio's CARLA

https://kx.studio/Applications:Carla

CARLA allows you to add a Gstreamer script in its JACK APPLICATION feature...then once the script is loaded, you can export the Gstreamer script as an LV2 plugin on Carla's RACK where it shows Gstreamer loaded up...

a Gstreamer QRQ CW bandpass filter(841 hz center freq) is created by using the following Gstreamer script:

gst-launch-1.0 -v jackaudiosrc ! audio/x-raw, channels=1 ! audiowsincband mode=band-pass lower-frequency=761 upper-frequency=921 length=480 window=3 low-latency=true ! jackaudiosink buffer-time=1000 sync=false async=false

- loads into the CARLA  'add a jack application'  experimental feature... then on the CARLA RACK, rt click and EXPORT it as an LV2 plugin this Gstreamer bandpass filter pass-through time only take about 7 milliseconds

     - from input - to output
