Sound Problems

I have encountered some problems with the sound.
The way I was going to create the soundtrack was to obtain and record the different pieces of music, and then edit them together in audacity, but it turns out I cannot, as all the different tracks go out of time.

I now have a new plan, but it will have to be done in the halfterm, quite close to the deadline.

I plan to call upon a couple of musician friends, and go down to a studio to record the piece live, in one take.

This could become quite problematic as relying on the people I need to call upon could let me down, but if it works well, the piece should turn out pretty good.
