I'm converting some E-AC3 files to opus. If I use ffmpeg to do it one step, I run into problems. So I wrote a simple script to use eac3to to decode to wav, then ffmpeg to convert the resulting wav to opus. It works but unless I specify -removeDialnorm, I get the message "keeping dialnorm" from eac3to.

I've updated my script to specify -removeDialnorm, but I thought that was the default anyway. Am I correct in wanting to remove dialnorm when doing this conversion?
