Monitor of Null Output

[kaihendry]

I can't get it working on Archlinux: https://s.natalian.org/2021-02-17/voice.mp4

Actually maybe I specified the your_mic_name incorrectly? Even when something comes out of Null output, it doesn't sound noise reduced to me https://s.natalian.org/2021-02-17/noise-removed.mp4

On your second video the output is not denoised, you should always select Monitor of Null Output, not the one with more verbose name. Working with PulseAudio is extremely intuitive...

I recently tried PipeWire + PulseEffects, but I felt even more pain, even though PipeWire should have solved all the issues with routing PulseAudio had...

Little confused how to address my microphone, did I do that right or should I be using the ID?

[werman]

I'm addressing by the name, the one in the second video seemed right

Isn't there a quick way to pry out the name of say the chosen microphone used by recording apps already?

I'm struggling to decipher pactl list sources short for my onboard / headphone microphone.

(ins)[hendry@t14s ~]$ pactl list sources short
0	alsa_output.pci-0000_06_00.6.HiFi__hw_Generic_1__sink.monitor	module-alsa-card.c	s16le 2ch 44100Hz	RUNNING
1	alsa_input.pci-0000_06_00.6.HiFi__hw_acp__source	module-alsa-card.c	s32le 2ch 48000Hz	RUNNING
2	alsa_input.pci-0000_06_00.6.HiFi__hw_Generic_1__source	module-alsa-card.c	s16le 2ch 44100Hz	RUNNING

I get quite a lot of pops and crackles using /usr/lib/ladspa/librnnoise_ladspa.so and the whole recording became unsynced when switching sources in pavucontrol https://youtu.be/16vH8J9shzc

Pops and crackling aren't expected, I didn't experience them. As for "attack and decay of voice" you could try setting VAD threshold to 0:

...  control=0

try latency_msec=1 on the modul-loopback line - it helped in my (crackling) case
