I'm looking for a cool audio editing software which is light-weight, capable of recording and multi-track editing, powerful while easy to use...... I know there's Apple Soundtrack Pro, and I tried it at the apple store, I think that's just too heavy for my 1.67 pb... Starting and processing takes too long... I know there's Deck(yeah, that's light-weight compared to Soundtrack pro), and after a try out I think that's just a little sophisticated for me since I'm no expert in audio editing, so I may not make good use of some "high-end" functions... Thanks everyone, I know my explaination maybe a little confusing..... but thanks, all the same.
