Arnndn error message
SUMMARY
***
I'm working on a long project and I can't find a properly working noise
cancelling plugin, so now I'm stuck with my horrible audio.
***
Plugins I tried:
Arnndn:
When I place it on an audio, it does not work, and I get this error message
after a while: `[filter avfilter.arnndn ] Cannot init filter`
Afwtdn:
When I place it on an audio, it does not work, and I get this error message
after a while: `[filter avfilter.afwtdn ] Unexpected return format`
Noise Supressor for Voice (Ladspa):
This was not even an option until I installed separately with this command:
`sudo pacman -S ladspa noise-suppression-for-voice`
After restarting Kdenlive, I could use it, but it was so dry, I wanted to tweak
the settings. I set the wet/dry slider to aroung 0.5 and the voice started to
echo. I can hear that the original and the filtered audio is playing at the
same time (maybe that's how it should work), but the two audios are a bit
slipped away, there is some latency in between, that's why it sounds like echo.

Questions:
- Is there any other plugins for noise cancelling I could use?
- Are there any solutions to fix the avfilter issues? Maybe lack of dependency
on Arch?
