The Levelator is a pretty basic application that serves a single purpose, but one that is very useful for podcasters with multiple participants. I use it for PreviewCast and phpBB Weekly editing, and even luminaries like Leo Laporte use it.

You drop an AIFF or WAV file on the Levelator, and the application then goes through and scans the different channels of the audio to equalize their audio levels. For example, when we record PreviewCast, sometimes we may have something happen where someone may be louder or quieter than everyone else, or there may even be a mix of volumes. No problem, I just drop the recorded audio on the Levelator, and it pops out a new audio file with all of the voices at the same volume. It works very well, and has dramatically helped to improve the PreviewCast audio quality.

Levelator does what it advertises, and it works very well. I recommend it for anyone who records podcasts over Skype or other teleconferencing methods, because it will make the quality of your audio SO much better, and you’ll practically never have to worry about volume levels of your participants again.
