There is a plugin software for audio mixing. Are you using Premiere Pro only or plugin software for audio mixing? Do you have experience with this?
I've seen a number of plugins for audio work. So ... which one specifically are you referring to?
Also, within Pr, there's the Essential Sound Panel which makes it easy to designate a track as dialogue, another as ambient sound, a third as music background. And set to auto-duck the others when there is dialog going.
It also includes some easy options for quick treatment of the file for normalizing volume and such.
No experience with that one. Hopefully someone may respond. I've just done my own audio work, it isn't that difficult for the things I do.
That mean you say without any plugin good audio mixing can be done only with Premiere Pro.
Yes, you can do some pretty decent audio fixing in PrPro. You can also use the option to edit the clip or sequnce in Audition to get a lot more options for audio work, but again, as an audio app, it's a bit more to learn.
And as noted, the ESP gives you some very simple options to do levels normalizing, auto-ducking of other tracks to dialogue, noise reduction and some other things.
