In Wavelab you can create extra volume points over your track by clicking on the volume line superimposed over the clip (Studio One looks identical - you just can't change the volume from being static over the duration of the clip). This can be useful when level matching an album or creating subtle dynamic moves in the mastering process. I would love the ability to create custom volume curves over the clip itself, or at least be able to automate the fader within a Project like you can in a Song.
I know you can split the track and adjust gain separately, but this doesn't address the dynamic nature of volume smoothing between two different sections of a song.
Thanks for considering.
