Question: also usable for output? about noise-suppression-for-voice HOT 5 OPEN

Something like this should work, change sink_master to your output (you could find it via pacmd list-sinks | grep -e 'name:')

load-module module-ladspa-sink sink_name=denoise_sink_for_apps.stereo sink_master=alsa_output.pci-0000_0c_00.3.analog-stereo label=noise_suppressor_stereo plugin=librnnoise_ladspa.so control=0

You should be able to denoise the output from the apps, I don't have exact config ready - https://github.com/toadjaune/pulseaudio-config could be helpful.

I don't see any complications or reasons no to do this.

Works! Should we document this?

Yes, however last time I tried I had some issues, I want to check if it work for me before adding to docs.

I spent a long time figuring out whats going on here, I was also experiencing issues with this one liner. PA in general seems to have some issues with resampling. And I would constantly get crackles in the audio.

The only way I could get it to work was an overly complicated setup to give PA a buffer before an after the ladspa sink, that introduces some latency.

load-module module-null-sink sink_name=nui_out_out_sink
load-module module-null-sink sink_name=nui_out_in_sink
load-module module-ladspa-sink sink_name=nui_out_ladspa sink_master=nui_out_out_sink label=noise_suppressor_mono channels=1 plugin=librnnoise_ladspa.so control=95 rate=48000
load-module module-loopback source=nui_out_out_sink.monitor sink=alsa_output.pci-0000_0c_00.3.analog-stereo channels=2 latency_msec=50 source_dont_move=true sink_dont_move=true
load-module module-loopback source=nui_out_in_sink.monitor sink=nui_out_ladspa channels=1 latency_msec=50 source_dont_move=true sink_dont_move=true

Maybe someone can find a saner way, but I couldn't get it to work stable on my machine otherwise.
