I've had some mixed success with Audition's de-noise and de-reverb to treat some audio shot with shotgun in a big, echoey gymnasium. The results are a little better, but I can't push the effects too hard before they start noticeably artifacting the audio.
I'm tempted to pull the trigger on buying the new Crumplepop de-noiser 2 while the early-adopter price is still good, but not sure if it's going to be that much better than what Audition has done for me already.
Anybody out there used both and have an opinion?
Failing that, do you have a better suggested workflow in Audition for killing extreme echo and preserving crisp vocals?
audition doesn't really have a dereverb that i am aware of. izotope rx has a really good one and its plugins import into audition. when i would use the noise print or learn sound model, i would invert it to only hear the noise. if I could hear talking, I knew it was pushed too hard. Also, multiple small passes give better results in audition than one hard pass. Play with the fft size as 512 is good for some and smaller freqs good for others.
i did try the old invert compression trick in audition. it's not as a good, but its better than nothing.
'Ye Olde De-reverb for audition
Make two copies of the track, placed exactly one above the other. Now invert one. The mixed result should be nothing if you've got it right so far.
Now start applying compression to only one of the tracks. You'll need to carefully adjust all the compression parameter so be very patient, pay attention to the threshold, you seem to need to get that just above the level of the echo. Adjustments to attack and decay times will have an impact as will compression ratio.
