Removing reverb from a sound file

How to do this, that and the other. Share, learn, teach. How did X do that? How can I sound like Y?

I was hoping someone could help me with this: I've got an audio file with some spoken text which has been recorded in a small room. The sound is relatively dry but you can definetely hear the reverb. Is there a way to remove this or at least diminish it? Thanks in advance for any advice!

Deconvolving I think is one way, but I don't think you can realy remove the reverb. You could gate out the spaces inbetween the words or edit those spaces out removing some of the tail, that would diminish the reverb a bit. And then EQ it.

Some fast gating/expansion, plus eq-ing out any dominant room frequencies. I'd also try using some noise reduction, but this can also alter the source sound at levels needed to reduce reverb.

Thanks for the advice! I'm not sure gating would work (the room effect is small enough to have most of the reflections in the signal itself, there's hardly a tail) but I'll see what I can do. At least its helpful to know there's no miracle cure for this. :-)

convert the signal to mono. takes out about half the reverb usually.

apparently if you have a recording thats majorly reverberant and you want to minimize the reverb supposedly feeding it into another reverb unit but with a much smaller room size actually gives the impression that the reberb is no longer there somethign i was told recently could be completely wrong but hey give it a go any way see if that works

Far out. I'm almost tempted to make a recording try this with even though I have no need to.

yeah it tripped me out as well when i heard it. i thought to my self how the hell does that work but if you think about it enough you can see the logic behind it i havent tryed it out yet but i will soon. baisicly say you recorded something in say the cistene ( excuse the mispelling) chapel ( massively reverbarant ) and then load it up in ya DAW and chuck a reverb in the chain with a small room size. its supposed to give the impression of a smaller room. if any one trys it let me know how it goes

I have 2 approaches the may work.. If the recording is stereo (or at least the reverb), doing a center channel extraction will get rid of most of it. Another cool trick (with Adobe Audition 1.5 + 2.0) is to get a fingerprint of just the reverb tails as if you were going to do a noise reduction and then do redux on the reverb signal only. Adobe Audition 3 is even better at this as it has adaptive noise reduction which is even more precise..
