I was searching the net for an audio editting application and I stumbled on the link below.
I have not used this product, have nothing to do with it and cannot recommend it one way or another <--- Sorry about that but thought I'd best say it
Anyhow this post is purely for people's interest, as well as audio editting they also have some video conversions which was my reason for posting as I've seen this asked before on these boards.

I'd be intertested to know if anyone has used either of these products.
Enjoy,
Brian
