Don’t have the time or interest to learn about proper mixing? Enter Levelator, a free application for Windows, Mac and Linux. From the Conversations Network website:
It’s not a compressor, normalizer or limiter although it contains all three. It’s much more than those tools, and it’s much simpler to use. The UI is dirt-simple: Drag-and-drop any WAV or AIFF file onto The Leveler’s application window, and a few moments later you’ll find a new version which just sounds better.
Personally I’m highly skeptical to shortcuts like these, but hey, might work for some.
