Thanks for the tip SlickCat. I'm using Audacity 1.3beta and I've had a quick go at what you suggest. Certainly does fill it out a bit! Not too sure how to get the delay time right though without any sort of tap-delay input and so this is a bit of a stab in the dark.
I'm also trying to figure out how to make Audacity save just the lead track. Even though I've created a completely new project without the BT, the file size remains at the original 3.6 MB regardless. Got to be elsewhere now but thanks for your input and I'll have another go at it later.
