If you are new the the world of podcasting or looking to record audio for a Youtube review and don’t quite understand compressors, equalisers and how to get your audio levels to sound the same there’s good news in the form of Levelator.
Having laid dormant as of the end of 2012, the Levelator program was abandoned apart from an update to get it working with El Capitan. Rather than try to explain what Levelator does here’s the blurb from the website.
So what is The Levelator®? It’s software that adjusts the audio levels within your podcast or other audio file for variations from one speaker to the next, for example. 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.
