Hmmm! have to look into it. What is nice with CoolEdit, though, is that you can alter the speed (keeping the pitch) with pretty good results to get the exact duration you need, as it is a simplified version of the pro version CoolEdit Pro, a true worldwide standard with music professionals.

Actually what we need (and what I use most) is the ability to cut & paste, mix tracks, fade and alter levels to reduce dynamics for best outdoor performance. Also switching from stereo to mono is a requisite when the music is played on a field with sometimes dozens of loudspeakers and over a line extending up to 1,000 feet.
