Audio Filter for poor audio

[Bouncing Account needs new email address]

I’m afraid if you shoot interview audio using the on-camera mic, these are the results you’ll get.

Good-qulaity audio simply must be recorded that way.
Echoey, hollow, “off-mic” audio is not correctable with any filter.

You need to get the mic as close as possible to the subject’s mouth.

A Lav mic placed on the subject, or a “directional” mic aimed at the subject’s mouth and positioned by boom or stand JUST out-of-frame are the best methods.

If the room conditions are still too “bad” for recording a clean track, you must either MODIFY (deaden) the room, shut down the noise-makers in the room, or CHANGE rooms.

I completely agree with Matte. However, you may be able to improve it slightly (doubt it though with the on camera mic). There is a plugin from elemental audio that I have reduced reverb effect with. The recording was good to begin with, but the room was not. It was a highly reverberant room. This can be done with many compressors and expanders, but this one makes it easier to understand and tweak than others. https://www.elementalaudio.com/products/neodynium/index.html The idea is to compress all the audio above a certain volume and turn it up to a maximum loudness, then expand all the audio below that same level and turn it down as much as possible. With a really poor recording, don’t expect a miracle, but the plugin has a free trial, so give it a shot.

Thanks,
