wmccorm,
Hi, Wallymeister here. You will need a digital audio editor program. I will recommend a program called Goldwave, from
Goldwave Inc. It is probably the best out there for the money. You can download and use a trial version to test out it's functionality and useability. It will give you the ability to do what you're wanting to do plus it has alot of other neat functions too.
Here is their website.

Hope this helps,
Wally
