Cleaning up spot recordings.

What are the tricks to get rid of the smeary boxy ambiance when spot recording from a distance in a hall?

I was at a festival on the weekend and caught part of a show on my little video/snapshot camera. While the audio is listenable (even though it's bluegrass), I wanted to try cleaning it up a bit to send to some friends. I was on the balcony of a pretty good sounding church, but the camera caught a lot of the room reverb.

I've sort of get it halfway there with either noise reduction or eq, but I'm sure it can be better.

While this audio isn't that important to save, I'd like to figure out the best tricks for cleaning up this kind of sound because lots of times I'll capture stuff on a field recorder and, while not usually this severe, it often has that "sound".

Don't suggest Waves plugs. I don't do those any more. I've got the PSP, iZotope Ozone and RX, and Wave Arts plugs, and various others.

I've got hardware too, but it's not worth going out of the box, I don't think.

Clean up

Unless you have a great deal of constant (unchanging) noise from the camera (or elsewhere), I would forget about noise reduction.

If you can't get things to your liking with simple EQ, then separate your stereo recording into MS. Try EQing each element individually.

It may not accomplish anything, but it's something worth trying and takes very little time to do. You can often find the nasty reflections in the side portion, and some reduction in the "mud range" of the mid, along with some HF boost in the Middle might clear things up.

It's a mono recording. Well, two channels, but the same track in each. They null out perfectly.

I'll tinker more.

Any coincident or non-coincident stereo recording will have a sum and difference. Maybe a mono setting or (large) design error on the camera?

If the two channels sum to a null, than you have a two mic mono recording with one microphone polarity reversed.

I'm not so sure it is a design error. It's a single little electret condenser built into the camera. I'm talking about a little handheld snapshot camera.

It's not a stereo recording; the camera creates a mono video file. When I extracted the audio, I created the file as stereo just to try some widening tricks.
