This program is bottom of the barrel. It doesn't even have native VST support. If you don't know what VST is, then maybe this is the program for you since you're obviously a novice with no idea what you're doing.
The only upside is that it's free. So if you're broke and paranoid and willing to settle for the smallest possible set of features and a crap interface (as it appears the community here is), this is the program for you.
Reaper (the cheapest DAW) is a better audio editor, and it's not even designed for that.
