Carla VS matrixmixer.lv2

Is this the Carla software you are talking about?

Sure.

Carla: https://github.com/falkTX/Carla

It lets me install any normal audio pro audio plugins, for example https://github.com/xiph/rnnoise

It also does some cable management, but qpwgraph is maybe better for that.

I looked at your code and the approach (IMO) is kind of bad.

If you want to solve the problem of "voice changer", you can skip the UI entirely and just use plugin parameters. You can also skip the problem of managing the connections. And when you publish your work, every pro audio software (Ableton, Reaper, whatever) can use your audio processing.

Hope that helps.

If you're looking for a realtime VST Host, I use Carla with the JACK Audio Connection Kit for low-latency EQ and other FX which are realtime on my Microphone, which then get redirected to a virtual microphone (all on Linux, should still be possible on Windows). So far that worked greatly.

You may also, if you haven't already, look into Carla as a plugin host. Carla supports midi and osc for control.

If you're using pipewire, easyeffects is probably the simplest road to take. A plugin host/patch bay like Carla is a bit more complicated but offers more flexibility.

here's a FOSS plugin https://github.com/werman/noise-suppression-for-voice you can use it with Carla https://github.com/falkTX/Carla

Carla is a standalone one.

Yeah, an old version of jack2 gets you that behaviour. See https://github.com/falkTX/Carla/issues/1274 and https://github.com/falkTX/Carla/issues/1268 for related discussions.

I was reading this on git : https://github.com/falkTX/Carla/issues/828 And found out the I only thing I need is carla-git installed to have this option . Now I have installed it , reboot my system, update and upgrade but there is still no "add jack application" option available. Is carla-git part of carla or is it different ? I'm not sure how to enble it probably? thanks for any answer .
