Let’s say I apply gain +2dB. Then I want to add 2dB more. I can’t do it in this window anymore. Just clicking “apply” again is ignored. I have to close the whole window and reopen it.
But I already applied 2. I need to undo 2 then reopen the window (because it won’t let me do sequential gains) and reapply 4. I don’t know I need 2 until I apply it twice. Instead of easy double gain I have to close window/reopen it (dig through menu tree) and reapply it.
It’s a really really dumb solution (not your fault, just the way this function implemented).
I lke to fintune my edits and do incremental steps. It takes a lot of clicking and window opening.
There is an option “auto apply” in that dialogue. Activate it and do your step by step adjustment while keeping the dialog open.
Also: Any offline process does not really change the original audio file. If you change the gain from 2dB to 4dB it will not be a gain of 6dB. It first undoes your 2dB gain and then applies the 4dB gain.
