Gstreamer 1 line of code to produce a 2 tiered, 2 tone, final bandpass filter for CW & PTT - AFCW - QRQ CW demo

[Chuck aa0hw]

brief demo of QRQ CW testing a Gstreamer CLI 1 liner - to get two different audio bandpass filters at the same time, staggered, and incremental, for their respective tones of 707 hz and 5555 hz

the Gstreamer plugins - interleave & deinterleave were essential in being able to create this filter...it allows a filter at the INPUT & OUTPUT... the first "input" filter has slightly more bandwidth and lower Q than the 2nd "output" filter for each individual TONE
