The short answer is, you don't. I think it might be possible, theoretically, with software, but I've never heard of such, and I can't believe it would work well. That's why we don't print reverbs until we're absolutely sure. If it was delay, I guess you could try cutting the iterations from the wav, but you'd probably have to add reverb afterwards to smooth over the edits. Why would you want to do this? Are you sampling someone, or did you mess up?
Izotope RX4Advanced has a Dereverb module that works very well, but is not perfect for every situation. You may want to trial it to see how it works on your material.
Depends so much on the material. Just using a transient designer on drums to dampen the sustain and crispen the transients can be a good start to recover, but you should be looking to re-record.
Fergler has hit the nail on the head A great take is more often than not and some say the only way and mostly the shortest way to a great sound! Grinder
actually yes i was looking for an alternative to izotope RX4 dereverb as its a bit expensive...i'll trial it though, they offer 10 free day trial i might like a sample with reverb, maybe i need to take some out, just in case i guess altering the decay would also help.....
What i like with Acon's deverberate is that it doesn't try to cut everything : it keeps the sound rather natural, so i would say it is quite safe to use (instead of trying too hard to remove all the reverb). You might also try Eareckon's Transreckon : it is a transient shaper, but afaik you can listen to the delta ( = the removed signal), and it works great.
