To remove unwanted sound/music between words (on the ripped-out center channel of the mix) you could use a gate, such as these free ones.
There is currently no known way to remove sounds under the speech without artifacts, but you could experiment with something such as this or this.
Noise/hum etc. removal plugins are also useful sometimes.

Fishmanlee has already mastered this.

It's called talent.

Have a look.

I'll have a go with the gate types on the programs I already have first, thanks for the pointer Satanika.

vbangle, I followed that thread (largely because I knew I would be attempting this mini project) so I wasn't ever convinced, it's never a good idea to make wild claims unless you can back them up with extraordinary results.

Still the kid at school who told us he was Superman really could fly (for a few seconds when we craned our necks 90 degrees).

It was a joke perhaps done in poor taste but...sorry.

I sincerely wish you the best and have faith that you can pull it off. Unlike fishmanlee who is just some kid trying to fit in...

well this is all i have to say.....i found one sound effect withought dialogue! yay! its its its a door clanging in jedi when the gate shuts behind threepio and artoo! its only on the right channel if you cut that you have no clang when the door shuts

Made any progress Bingowings? Being able to minimise the music would make my edit one hell of a lot easier.

As I posted on the other thread I've had limited success by going back and working on it from a word to word basis (which is very very time consuming).

There will be instances where it may be necessary to go further and break into longer words and strip the sounds at either end and then apply a gate to the remaining sound componants and then reassemble them (and even then it will not be perfection).

If we has a team of people with no friends and no social life who could do this for each character we might get a workable dialogue bank by 2017, it really is a labour intensive job with no quick fix solution that I can see (other than breaking into Fort Skywalker and liberating the data tapes).

Are there any key scenes you need attempting?

personaly probably only scenes that have alternate cues for the scenes

Pretty much every scene in the film is being rearranged, so the music won't match up when there's a cut.

What do most editers do about this? Add sound fades to make it less jarring?
