I am not sure I'm using the right words, there's a lotta lingo, but the issue I've been having is if I select a small section of the spectral waveform with the marquee or lasso tool and attempt to change the volume with the HUD display, it makes the 3 seconds that are selected in the marquee tool as well as everything underneath/below silent. It's super weird, I tried selecting like the smallest area and making the smallest volume adjustment and I have the same effect- just a random silent blip in my track. Please help, trying to get rid of mouth sounds. 😞
I just tried doing what you have said you are doing and Audition is function properly - just the section selected is affected.
Just to be clear, you do realise that the spectral display is showing frequency and you are turning down the volume of the frequency section selected?
What version of Audition are you running?
Mac or PC?
