Isi it possible to balance audio in MULTIPLE clips in Premiere Elements 2020?
I have PE 2014 and am thinking of upgrading if the audio editing faciilities are more powerful.
If you're asking if you can mix the levels of several audio sources, yes you can.
I'm not sure what you mean when you say "in one operation". But the tools for mixing audio are the same in version 2020 as they are in version 14, if that's what you're asking.
I don't think Normalize works like that.
The answer is yes.
Select all clips.
Right click > Clip > Audio Gain > Normalize.
