Hi,
From where I am, gain staging and peak detections are.... Boring.
The shortcut,for me is to clone the track ,normalize the clone to zero dB and make the substraction ( if it is the proper translation for:"soustraction ").
Faster than let the track go to the end ,click: "keep peak or something" and see what number is written.
I'm sure it won't be a hard coding task to have a kind of knob which would tell us what is the peak level of a track as far as all the functions already exist within Sonar. It would spare time,click and writing operations.
Just a thought.
Cheers and best wishes to all.
