Quick Audio Fade Between Clips

When editing a timeline and say that it's a clip that was a 30 minute recording, but I'm cutting out dead space between the good footage. Do you guys have any recommendations for the audio as in should I do a quick cross dissolve between the cuts for the audio like a frame in and a frame out to "blend" the clips so there's not a pop or noticeable change in the background noise as it cuts.

Back when I was learning editing they taught us in Pro Tools to do a quick frame cross dissolve on the audio clips.

What do you guys do?

It depends on the cut. If there is a pop, yes use a fade. Going from one background to another I would use a cross-fade, either separate overlapping tracks (the preferred way) or on a single track. Length of the cross-fade will depend on the source material and what it sounds like.
