Removing dead air within projects

Good afternoon everyone,

I am trying to be better at maximizing my time for my projects, but the thing that keeps holding me up is editing out all of the dead air that is in my projects. The tutprials I found online don't seem to work and I am not sure why, can you help?

Here are some steps I have taken so far and some details of the projects I am working on.

- The footage used are primiarily video games with 3 main audio tracks. The game audio, my audio, and combined audio (the third one is for just in case scenarios otherwise it is muted).

- I have opened the project in Adobe Audition but I wasn't able to find the sequence even when I named it differently so I can find it easier.

- When I do a "edit in audition" it brings up the clip, but I can only see one track at a time within the waveform.

Would I need to save it to see a multitrack first before I can try the diagnositc steps or is there a simple way to do this? Any hints are appreciated and thanks in advance.
