I just wanted to share a tip here, as my microphone is shit. In pulseaudio I could fix with that module, now in pipewire I just imported the module, configuring the file ~/.config/pipewire/pipewire-pulse.conf.d/99-echo-cancel.conf with:
context.exec = [
{
path = "pactl"
args = "load-module module-echo-cancel aec_method=webrtc aec_args=\"analog_gain_control=0 digital_gain_control=1\""
}
]
After this, restarting pipewire with systemctl --user restart pipewire pipewire-pulse, the source appeared and the sound from the Echo-Cancel Source is much cleaner than my microphone.
As I don’t hear anything talking about this, this might be valuable information.
This is a really cool tip!!

I’ve used it in the past to clean up a table mic for voice chat and worked pretty well. Requires a lot more config work than your approach does though.
