very useful instructions: https://www.amirsharif.com/using-ffmp...
github models: https://github.com/GregorR/rnnoise-mo...
commands:
unzip the github models
unzip rnnoise-models-master.zip
extract audio from video
ffmpeg -i inputvideo.mp4 outaudio.mp3
arnndn command
ffmpeg -i outaudio.mp3 -af arnndn=m=rnnoise-models-master/somnolent-hogwash-2018-09-01/sh.rnnn a.wav
combine original video with new audio
ffmpeg -i inputvideo.mp4 -i a.wav -c:v copy -map 0::v:0 -map 1:a:0 new.mp4
extracting just the noise from audio
