Hi
The only LV2 recording plug I'm aware of is screcord.
https://github.com/brummer10/screcord.lv2
It is made for running on MOD devices, but works as a plain LV2 plug as
well. It has a mono, stereo and quad recording module. Still there are
not more controls then start/stop record, vumeters and clipping
indicators, but they are forwarded to the host so should be usable on CLI.

  Hey hey,
 I just heard that Ecasound, as robsut as its code is, is slowly moving
 out, requiring more and more patches. So I should really look for a
 new solution.
 Why CLI? I had a GUI running on my system, with JACK, and found that
 Orca was very sluggish, not condusive to fast efficient work. Besides,
 there are quite a few LV2 plugins which are built on JUCE and JUCE Uis
 are not accessible on Linux. Last thing I heard, they added
 accessibility but only to mac and windows.
 So back to the commandline. LV2 plugins can be controlled there,
 mod-host a case in point. Though, admittedly, I found quite a few
 plugins with quite meaningless parameter ranges. Still, they can be used.
 Does anyone have any ideas? Perhaps something that is in its early
 stages or a UI that was created for testing or automation and might
 offer more beyond that purpose? -- Any suggestions or hints are
 welcome. For the time being, Ecasound will run, but its life-cycle
 looks definitely finite in the foreseeable future.
 Best wishes,
 Jeanette
