Is there an effect or process that will have the opposite effect as reverb? I need something to take away reverb/echo, etc.

Unfortunately, no.

Take Care

"Sometimes", reducing the stereo width can attenuate it.
Process>Pan/Expand: Move the adj bar down towards "Center".
This may only work on a stereo file and if the reverb is in stereo.

Noise-gating can get rid of tails, but the result is usually is fairly crude....

Like most "cleanup" techniques, this works best if applied conservatively and the recording contains a small to moderate amount of echo:
I initially posted it a couple of years ago.


---------------------------------------------------------------
Here's an old trick (from and old dog) dating back to analog recording days that usually gives some improvement (you need a good wave editor like SoundForge):

1. Select All, then Copy the audio.
2. Paste to a new track, invert the waveform, and apply moderate compression.
3. Reduce the new track volume so that a preselected "quiet" area is about 50% of the level of its corresponding area in the original.
4. Paste Mix the new track into the old. Renormalize if necessary.

There should be a noticeable improvement in clarity and echo reduction because you have applied negative feedback to the areas where the echo is most objectionable. Too high a compression or too high level of the feedback track will give a "pumping" effect, however.

I've never tried this, so beware, you could waste a lot of time but the idea sounds feasible.
IF (really big if) you had an acoustic impulse of the space you can use something like acoustic mirror to subtract the echoes. Just an idea.
