I think ffmpeg is not able to do advanced audioprocessing at the moment.
But what could work is piping to an audioprocessing tool, like SoX for
You can do all the commands in one line by piping with "|" (vertical
bar, not big i ...).
A pseudo command can look like this:
ffmpeg -demux to wav | sox -do audioprocessing | ffmpeg -videoprocessing
and take sox input as audiostream
With a little Batchscript you can create a watchfolder which processes
every file you drop in it...
It's not the smoothest solution, but it should work. (I both steps
(piping and watchfolder) independently on a linux system, but they
should work combined aswell.)
