Consolidating audio makes a HUGE difference to how much work your computer is doing in the background.
Before you consolidate a track the computer has to go through all the edits you've made, decide which edits to keep and which edits to ignore, seek, find and load each correct audio clip, make edits to the selected audio clips, make automatic crossfades at the beginning and end of each clip and then play the resulting audio clips as one continuous audio track. More edits means more tasks to perform prior to playing an audio clip.
Consolidation means just that, all the final edits are combined into one, continuous audio track.
If you're editing audio tracks section-by-section (let's get the bass intro right, let's get the bass first line of verse 1 right and so on) it doesn't hurt anything to consolidate an audio track every few edits.
Create four habits to help reduce program and computer crashes: frequently consolidate audio tracks while editing, frequently save work-in-progress song projects, frequently delete back up and temporary files that are no longer needed and frequently defragment your computer hard drive(s).
