Yes, you just spotted the error in the numbering. I just misnumbered the posts, so the 4th is after the 5th. Sorry, but enjoy the tip.
Many times we need to see every detail, other times have to see the whole picture. During editing for example many times I adjust the waveform height to fit the purpose.
This is another function which is adjustable directly with a mouse/touchpad, but in my opinion keyboard is more efficient here.
Waveform height adjustment: cmd+option+[ or ]
Frankly I use this all the time even when I’m back in the studio environment. It just helps a lot, allow you to see very low level material or adjust a some normalised stuff to see what’s going on.
