I was recently contacted by a staffer that had wildly differentiating audio levels for participants in a Zoom recording:
They had tried using “Normalize” but unfortunately the difference between the two was too much for that plug in to handle. This looks like a job for the “Hard Limiter”! Hard Limiter is a standard plug in available in the “Audio Effects” panel of Adobe Premiere. Most NLE’s will have a similar plugin.
If you measure the max level (in db) for your lowest audio, you can set your hard limiter to that level and it won’t allow any of the other audio above that level. This won’t help if one of your audio participants are over modulated or distorted.
In today’s world of remote interviews where we have no control over the participants audio, the hard limiter will be of great value.
