Is there any way to make REW run on Jack? I would like to make some measurements with EQ plugins running.

Re: Pipewire system room correction plugin
I haven't run REW for a while but recall I wasn't able to get it to work via JACK. Would like to be proved wrong though. It should be possible via PA>JACK bridge at least.
One could run pink noise from an external source and analyse it with REW's spectrum analyser. That would require a way to directly send the audio to the speakers rather than via the computer. You can download a pink noise sample from Bob Katz' website - https://www.digido.com/downloads/ (requires registration) in the "General" section.

Re: Pipewire system room correction plugin
Just a little update that could be of @sunrat's interest .
In a chat with falkTX some days ago, I discovered there is a way to use a plugin with carla-single and save the plugin state by sending a SIGUSR1 signal, carla-single will save a carxs file in the current directory.
Here's is an example setup with RaySession, launching Cardinal lv2 with carla-single, and have it saved in the session subdirectory:

Thanks @LAM . carla-single is nice, I used to use it (with EQ10Q IIRC) but now use the standalone JACK LSP PEQ16 which can save and load its own config file.
Like your sig btw. One of my pet hates is mixers who mix with their eyes. Heard some shocking live mixes that appear good on the screen.

Once I got it running, but it was a hassle.
One can do the test with e..g. Reaper.

Re: Pipewire system room correction plugin
I notice you have implemented this in v1.2.5 . Not tried yet but thank you (once again ).
Copied here for easier knowledge sharing:
In some cases, when the standalone version of LSP plugin connects to JACK, it is very useful to estimate connection between it's input and output ports and other JACK applications.
The connections should be specified via the command-line option in such manner:
<plugin-name> -x <input-port>=<output-port>
Where one or both of the ports is an LSP plugin port and the second port identifies the port of another JACK client.

Re: Pipewire system room correction plugin
Yes, here's the example:
Code: Select all
-x system:capture_1=in_l,system:capture_2=in_r,out_l=system:playback_1,out_r=system:playback_2
You also may specify multiple '-x' options.
