What plugin for dereverberation? at DVinfo.net

Hello.

I have some footage with voice of a woman that has too much reverberation in it. I'm looking for a dereverberation plugin to fix the problem. Any idea?

From my experience, you can't do too much about reverb. Adobe Audition has a spectral editing screen that can help you by cutting out the offending frequencies, but it's not even close to perfect for reverb.
Sorry...

Sorry, once you have reverb, you will always have reverb.
You can add it in, but can't take it out.

I don't know where or what you recorded to get reverberated sound, my guess is a shotgun mic used indoors. If this was the case, then for the future don't use a shotgun mic indoors, as they are too directional, and sound is still picked up in the mics shaft, and will pickup room reverberation.
If you can, use a cardiod or hyper-cardiod, but mic your subject close, as that will give you the best results.

A shotgun would pick up less reverberation. You may still want to avoid them anyways because the reverb sounds really weird, which is why many people recommend you use a hypercardioid instead while doing indoor recordings.

The standard dereverberation plug in is called "ADR in a treated room".

A scientist with too much time on his hands could probably develop a custom algoritm to remove the reverb from your clip specifically, but the parameters would have to be reworked space by space.

It's akin to correcting the flaws from the Hubble Telescope in post. It has been done. But give the researchers a new telescopic flaw to correct, and the work begins alsmost from scratch.
