Noise removal for other platforms?

I really don’t know where this question should go. I am curious, is there any way that the Audacity Noise removal tool could be used in another platform (like Adobe Audition). Audition has a similar tool, but in my opinion for what I am doing I can get far better results with the Audacity tool, but having to export to wav then import to Audacity then export again just runs too many risks of over processing (which has happened leaving artifacts sometimes) switching between 16 bit and 32 bit and such.

So to reiterate, is there any way to use the Audacity noise removal tool in another application. Maybe it could be ported to be used as a VST or something? Or maybe it’s already possible?

No there isn’t, because it is an integral part of the Audacity code rather than a separate plug-in, but if you use Audition, persevere with the Audition effect (read the manual if necessary) because the Audition Noise Removal really is very good - better than the Audacity Noise Removal if you get the settings right.

Thanks for the reply Steve. That’s what I was afraid of. The problem I am having with Audition’s noise removal tool is that it seems to be acting partially as a gate and there is a slow fade of the noise after louder sections of audio. It is noticeable and it is a problem. I can’t seem to find a setting to fix this . . . Audacity’s engine doesn’t seem to do this. I guess I’ll have to do some research. Again, thanks.

It’s probably good to know that many noise reduction programs (including Audacity) have some provision to do this. It’s very difficult to remove hiss from a voice, so provision is made not to try. Gate reduction on and off during speech and if you play your cards right, nobody will notice because the voice will cover up the noise. That’s what the Frequency Smoothing and Attack/Decay settings do. I bet there are similar adjustments in Audition.

If you don’t do that, you will get the complaint of bubbly, distorted voices. Hiss and Voices are direct enemies of each other and hiss is a very common result of quiet or poor microphone systems.

“My podcast has a background hiss in it. How do I remove it in Audacity?”

If it’s bad enough, you don’t.


Actually I find that if I choose a good sample in Audacity it removes hiss amazingly well with zero noticeable artifacts in the vocals. I have a great microphone Rode NT1A with a great interface Scarlett 2i2. The problem for me is my laptop fan. With nothing no other noise I usually run between -45 and -38 dba before noise reduction. I can typically, in Audacity, drop this to inaudible levels with zero effect on the quality of my voice (for audiobooks i.e. no music bed or other way to get hide noise). However, as I said using other tools I’ve found either there are lots of artifacts (the filter in REAPER) or the gate closes too slowly leaving an obvious transition after the audio (Audition). I am surprised at how well the Audacity filter works for my needs. Kudos to the coders of that filter for Audacity. However, I don’t know how the Audacity tool would do with other peoples needs.

Anyway, I will have to continue to research and play around with the Audition tools as there are some exceptional tools in Audition that I really can’t do without.

The problem for me is my laptop fan.

Doesn’t count. A rotating fan has periodic artifacts and regular spectra which lends itself to noise removal. Particularly if it’s low level and you get the gating right you can do very well. Pink or white noise as from a microphone preamplifier has flat energy distribution. Noise Removal obediently generates a filter that removes everything. Instant martian voices, particularly if the noise is objectionable.

The point that noise is objectionable is the exact point the tools stop being helpful.

Look for postings that begin: “Can you clean up…”

Almost always kiss of death.
