I think you could do this with a server-side audio manipulation tool like 
sox. When we built an online music store site, we successfully used it to 
generate the 30-second preview clips by trimming a section out of the 
middle and adding a fade-in and fade-out on the ends. I haven't tried 
doing anything with channels or mixing, but I think it might be able to do 
that.
