Bring voices of several speakers to the same level, with Levelator
Levelator is a free program that adjusts audio levels of a podcast or other audio files, for example to equalize differences between two or more speakers. It’s not a compressor, normalizer or limiter although it contains all of these functions.
Just drag-and-drop any WAV or AIFF file to the Leveler and after a while you’ll find a new version sounding better.
You may need the Levelator if you record interviews, panel discussions (when some persons are close to microphones and others not), etc.
Levelator is a program that works, if you need this job.
