is there any technique of removing reverb from a sound clip with out altering the original clip?

There's a couple of things you can do to reduce reverb.

What sort of equipment and plugins do you have?

A multiband compressor will certainly do a good job. A simpler option (that I found quite excellent) was SPL's De-Verb. Simple and effective.

Is it reverb that is a problem or is something off mic? There's little you can do about the latter.


I did a quick demo for De-Verb.

That is crazy. De-Verb. Can you post some examples? – Steve Urban Sep 21 '10 at 16:02

This question is very common, and you can find elements of answer here or there

Basically, your tools to fix problematic production sound are multiband compression/expansion, EQ and some more advanced processes like the ones addressed in the second topic I provided you with. But again, not a lot you can do, you can make things less worse and I've had a good experience on a film I made earlier this year.

Some good advice above however if you approach the task with the following in mind you'll be happier with your efforts.

Removing reverb from a "continuous sound" i.e. a train of impulses like speech or music where the previous envelope causes the reverb envelope to merge with the next direct sound envelope, is like trying to remove the egg from a cake :-)

If there is sufficient gap between the direct sound and the reverberation curve, i.e. after the 1st or 2nd early reflections you stand a good chance.

If the mic is at or beyond the "critical distance" you have very little chance.

I saw the multi-band compression comment - that can help - but I know that it would be around the same mid-range frequencies in the tails. My first try would be by using a gate to remove the tails, as they would be lower in amplitude. Maybe use the MBC to pull down the extraneous, and really, if you want to get down to surgical - use iZotope RX to erase the non-transient information using the spectrograph and scrub out tool. That software works wonders.

+1. RX is a truly stunning tool! – ianjpalmer Sep 24 '10 at 8:33

The demo of De-verb is no longer on the link :( Anyone have a demo I can listen to someplace?

I have a shoot coming up where the one room is extremely bright and reverbial is there such a word?) and I will have to try match the sound from other locations. I am researching as to what my options will be and any help will be greatly appreciated!

I've gotten good results using multi-band expansion plug-ins like Waves C4. It's useful because you're not cutting the tail, but simply attenuating it so that the decay happens faster. You aren't going to be able to get rid of all of it, but you can definitely reduce the presence of the reverberation.

Dyvision's plugin can be useful. I actually use it as a noise reduction effect, particularly for removing low level outdoors rumble and noise, indeed I get better results from it than plugins costing many times more.

I've always been pleasantly surprised with what de-verb can do. You can still use it do much and screw things up but it's been a life saver a few times. There are times when tools that just do one thing are great.

I second SPL De-verb, absolutely fabulous plug.
