I'd actually just use Audacity. It's free and very flexible and will do all you want and more.

Pro Tools is overkill and over priced with a very expensive subscription model.

For the professional making a living these costs are part of doing business but for your purposes Audacity is more than enough. Download it and try it for a while and see if it works for you. You've lost nothing by trying.

Educational versions of Pro Tools are little cheaper but are not upgrade able. When the next version comes out if you want it you will have to buy the next version with no upgrade reduction in price.

Also you cannot do work for money with the educational version. It's exactly the same software just the price and license are different.

Also Pro Tools HD is only available with Pro Tools hardware.
