Noise Removal causing Echo/Reverb
I am trying to edit some old home movies with a whole lot of noise. I have been able to remove a lot of it using the Noise Removal effect in Adobe Auditon CS6, but I keep ending up with a very echoy, empty sound afterward. Most of the audio is vocal. I have tried using equalizers, but still feel like it has given me a pretty hollow, inside-of-a-fishtank sound.
Has anyone else experienced this, and do you have any tips for how to avoid it or work around it?
Thank you -

I haven’t experienced your result, but I have found that, many times, the character of the audio is altered by removing noise, and not always in a good way. Something to try is to use the same settings you originally used – I’m guessing that you sampled the noise floor (Capture Noise Print), then removed that from the audio. Try applying it in a less aggressive manner. If I remember correctly you change the Noise Reduction setting. There’s a comment in the help file which says that “excessively high noise reduction levels can sometimes cause audio to sound flanged or out-of-phase.” Sounds like just what you’re experiencing:

With real heavy noise reduction you’ll often get that flanging/phasing result. Back off on it some and try again. Also, you may want to try adding just a touch of reverb to start fattening up what’s left. Then go to EQ for any fine tuning. And always send a version to Premiere and listen to it there before you think you’re done. Sometimes things get lost in the translation.
Also, try a notch filter instead of the noise reduction ones as removing a constant noise in a definable frequency can often give you much better results.

Thanks a lot, Paul. I’ll give those suggestions a shot.
