it is possible to apply echo cancellation to microphones while they are recording, e.g. like this

How can I apply the same filter to audio files that already exist?

If there was a ffmpeg filter for this, it would be applied like this:

ffmpeg -i FileWithEcho.mp3 -v $module-echo-cancel FileWithoutEcho.mp3

I am not aware of any echo cancellation filters in ffmpeg. – llogan Feb 11 '20 at 00:22
it wouldn't have to be ffmpeg any other software would be fine too – wotanii Feb 12 '20 at 08:32
