Can I reverse the Noise Reduction Process in Audition?

[Eightbyten]

I have taken the Noise Reduction Process too far and am left with a "tinny" sounding audio with slight echo. I somehow saved my work and can not undue it in the history panel. Is there a way I can reverse what I have done?

Please help if possible!!

Thanks,

Anthony

I'm afraid not if you actually saved over your original audio file. That is why you should always work on a copy of your original audio file when editing in Waveform view or use Save As to give your edited version a different name. A Save As is always the first thing that I do when opening a file for editing.

Thank you for the response! I will definitely take your advice for the next project!!

Any tips on how I can make the most of my situation? The audio is not completely ruined but does not sound great. I am putting it over a background track and have isolated the background noise (that I originally removed) and gradually introduced it as another layer of audio.

I am searching through tutorials and trying different approaches but any further advice would be welcome!

Thanks again!

Sorry can't really offer any more advice at this stage except for trying to mask the bad effects as you have done. It is always best to do less rather than more Noise Reduction and, if necessary, repeat several lesser reductions a bit at a time with a new Noise profile on each iteration and. some advise, increasing the FFT size on each pass.

That may help to an extent, but because that original sound was removed by a process involving a FFT (and some statistics), just replacing it won't get rid of it anything like completely. Sometimes, just creating a noise track and adding a small dose of that can help, but unfortunately, as mentioned previously, this isn't a reversible process.

In general, you'll get away with a higher level of noise removal with a higher FFT setting, but that won't necessarily help with LF noise. So to an extent, you have to look at what you've got in the way of noise before deciding what the best course of action is. Generally, higher FFT numbers work better, and with fewer bubbly artifacts.

Also you may find in future that the new DeNoise effect (new to CC 2019) works better and would be simpler to use in your case. Probably worth a try next time if you have a similar problem.

I had the same problem and luckely I found a way to fix it but only if you have send the audio clip from premiere to Audition. If so you can right click on your audioclip and click restore unrendered. That did the trick fore me.

Can't seem to find the option "restore unrendered"
