How to use a jack route as a single audio-filter with ffmpeg

Question

I have configured Ardour and there,

• An audio track takes input from a Jack-Sink device

• Applies some effects by using some Aux-Send

• Outputs the final audio to Master which is a Jack-Client

Now, I want to use this whole route as a single audio filter something like how lv2 can be used as a filter in ffmpeg.

That is, my virtual (expected) filter's input line is a Jack-Sink, output line is a Jack-Client.

Is there any such filter to use with ffmpeg ?
