Crossfadiing of audio edits is essential to arriving at a seamless result when joining tracks together. If it isn't done, the edits will instantly stand out and jar the listener away from their suspension of disbelief, which is the very last thing you want to happen in something that is supposed to be an uninterrupted movie experience.

Edit points must also be chosen very carefully, particularly when there is music involved. Trust me, I wrestle with this kind of thing all the time . . .

I do have fading between the audio cuts which makes it a lot more seamless than if it wasn't there, seamless enough that the audio doesn't take me out of the film at any point but I do not believe it is crossfading. If crossfading can make it even more seamless then that would be great, I might as well give it a shot and i'll learn something new in the process.

I did actually spend a few weeks carefully choosing the audio edit points of the three semi-specialised editions a year ago to make the edits as seamless as possible so I know exactly what you mean hairy_hen.
