How to delete background PC/UPS fans from a voice track?

Sylk wrote on 9/5/2019, 2:50 AM

Hi,

With Vegas Pro 17, what is the best way and solutions to denoise/delete, a continuous fan noise due to a UPS placed under my desk (also probably slightly from my PC) ?

I can not achieve a satisfactory result without cutting my sighs, words parts or altering the vocal frequency, but I want to keep all of that.

The recording conditions are really not ideal, but I would like to exploit them. Even if I do not expect miracles, I want to limit the damage.

I don't have VP17 & not sure what audio options it has for noise reduction. It sounds like you tried noise gates and equalising. I use adobe audition to attempt to remove background noise via creating a noise print of background noise. Has a number of options, but for free there's Audacity. They both can create the mobile phone speaker microphone effect (hollow, synthetic). It may be understandable but sounds terrible. Reduce the background noise reduction until you get a compromise.

Audition allows you to load the original video file, with Audacity I believe you must demux or otherwise extract an audio track to use.;

*The 2 audio tracks (game and micro) and video are separate files. I can work with the microphone track alone, so no problem about that.

If you can afford it I'd get iZotope RX (even the basic Elements edition would be fine) as it has a very useful Voice Denoiser VST plugin that works a treat in VP17.

To completely remove the fan without cutting things like sighs might be tricky though as these are likely falling into the same noise floor as the fan (although if they're significantly louder you might be able to gate out the fan with a very fast gate). If you've got room reverb in there that you need to get rid off you might need a higher version of iZotope RX (not elements) to get de-reverb or if you have access to Adobe Audition that can do it (or Accusonics ERA plugins but they are very expensive for the average user).

Audacity can do some things for denoising too, but is offline and destructive editing - using iZotope RX would be non-destructive if you wanted to change anything.

Oh and there is a denoiser in Resolve (Free) in the Fairlight page if you have that?

I second @jrb101 comment.
I also use iZotope RX Elements to remove fan noise and it does an excellent job!

You are in luck if you want to give iZotope RX Elements a go.
They have a flash sale on right now!
You can buy just RX Elements for $30 or the entire Elements Suite for $99.
I own the Suite.

Absolutly no reverb in my room.

Really a good new this VST.

Wow nice sale! Thanks a lot for advise.

Everything seems to indicate that the RX Elements appears as the ideal solution for me.

 

Not excluded that I come back to you to advise me in its use.

@Sylk ... also consider Steinberg's SpectraLayers 6. RX and SL are both spectral-based - but in many ways, they operate in quite different ways. SL has a very good noise reduction process and, overall, it offers much more of a surgical experience than RX (which is excellent is so many other ways especially in the full versions). SL is more expensive as it doesn't have an 'Elements' version as far as I am aware, but it does have a trial version which might be worth checking out first. iZotope products are without doubt excellent, but the Elements versions are basic.

I suggest to have a look at both products to see which best suits your needs and ease of use for you … as well as budget considerations.

All the later versions of Sound Forge Pro ( going back to SCS SF Pro 8 or 9), includes the Noise Reduction-2 suite. SF Pro 13 includes the NR-2 suite and iZotope RX Elements.

Sylk wrote on 9/7/2019, 10:07 AM

I bought RX Elements and the result i got is much better than all what i did without it, indeed! Maybe i can do better but now it's really more audible and acceptable.

Here's a video to hear the difference between original and denoised. I didn't apply eFX compressor to comparate.

Be careful, decrease volume level before launch it. Ajust it after.

(sorry for vid quality but forum limits upload weight... the important the sound is ok)

@rraud @Dr Zen @jrb101 @Dexcon 

I have an issue with very old material, camcorder zoom noise, quite bad. I tried Audacity but although I have been successful with it previously it may not be up to it. Have done some samples, too much damage. I have Sound forge 13 but its audio restoration seems limited.

Any ideas, would say RX7 be a good choice? Audio is not my strong suit😩. Is RX7 a stand alone program or an add on to VP? Thanks.

It's a good choice, worth an investment. There are plenty of tutorials in their YouTube channel on how & when to use every fx.

It's a stand alone program but you can integrate it in VP via audio preferences & set as your preferred audio editor, after that you can right click any audio material in your TL & open it in RX7 to enhanced.

@Former users ... +1 as per ram17.

Re the YT tutuorials for RX, have a look at this one, particulalry from 03:40, as it looks at how to remove a distracting noise (a whistle):

The camcorder zoom noise will possibly be at a lower frequency and possibly cover a broader frequency range, but the removal process will be much the same as shown in the above tutorial.

SpectraLayers 6 (SL) performs fairly much the same task, but RX has the advantage of being able to adjust the shape and position of the highlighted selection; whereas SL6 only allows for the highlighted area to be repositioned but not resized or reshaped. To do that, you need to perform the highlighting process again.

When the frequency size of the noise removed gets larger, the removal becomes more obvious, the 'hole' created by the removal becoming audibly noticeable. This is where I mostly use the cloning process (à la copy/paste); so, instead of using the removal process, I copy a selection of the audio prior to or after the offending noise, and paste it over the unwanted noise. Depending on settings, this replaces the unwanted noise rather than removing it and leaving a 'hole'. IMO, SL does this much, much better than RX as there is a lot of flexibility with SL as to the source of the audio to be copied; with RX, the replacement process is limited to a small selection just either side of the area highlighted to be replaced. Unfortunately, there are no tutorials as yet for SL6, but there are some tutorials from previous years on YT such as:

Beyond spectral editing and repair, RX has a heap of audio plugins in the standard version (even more in the Advanced version) some of which will appear as audio plugins within Vegas Pro. OTH, SL is just for spectral editing and repair and is without additional plugins.

Both RX and SL have trial versions, so it may be well worth your while trying both and finding out which best suits your workflow.

@ram17 @Dexcon Many thanks guys, just the information that I need. I had looked at the RX stuff on their site, forgot about YT, those two tutorials are excellent. Next step is to download demo's of both and get to work.

I've been putting this off for quite some time, time to bite the bullet.

@Former users Choose the VST folder (C:\Program Files\Steinberg\VstPlugins\) from Preferences "VST Effects" tab, and it will be added to FX.

@Sylk Ok, thanks for that, very nice to have as an FX. I better start on those YT tutorials for both, to get a feel for them, then check out the trials/demos.
