A waveform will allow the user to locate areas that need adjustment at a glance without having to listen to the audio over and over, like syllabe loudness/dinamics and syllabe coda/onset.
In the image, you clearly see the coda duration on the second note, and maybe I need a dinamic fade on the last one.
This would be great since dynamics is one of the parameters i struggle with the most. I can never really tell if something is too loud or not loud enough.
I would really appreciate this for better control when tuning dynamics and volume TBH
I got corrected for asking to be able to split notes - watch out.
