Levelator® adjusts the audio levels within your podcast or other audio file for variations from one speaker to the next, for example.

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.
