Izotope RX Noise Reduction & Restoration Plugins

Izotope RX

hey posties-

i think this has been covered, so forgive me but...

anyone had a chance to put RX through it's paces? specificially, how
does it work as a PT plug-in? better/worse than stand-alone?

i'm thinking of getting it to do some surgery on a doc i'm about to
mix. there will be lots of tattoo gun noise on the dialog. seems like
a great solution for reducing this noise...i should be able to see and
draw the relatively steady tattoo gun noise out, yes?

thanks for the real-world opinions my friends,
marty.

the spectral repair is much more useful than any of the other plugs.
i prefer other denoisers/decracklers over RX.

i don't think you're going to have a lot of success removing the sound of a tattoo gun, personally.

I find the stand alone version much easier to use than the Audio Suite version. Spectral repair is really cool, but it can take a lot of tweaking to get working well. I'm sure the tattoo gun will have lots of harmonics so you may or may not have luck. I've been amazed at some things that it can clean up, and disapointed with others.

Also, in the version I have (the ~$300 version) spectral repair only works on a chunk of 4 seconds or shorter. Perhaps the more expensive version doesn't have this limitation, But I don't know.

I have the full-up standalone. It has been a worthwhile addition to my NR toolbox--more for how it deals w/ broadband noise than anything else for me. It is still a "fingerprint" style NR system, but I prefer its sound to that of Z-Noise, which I also have.

Ditto on the standalone version vs RTAS. I tend to prefer the waves decrackle to the iZotope. I haven't used the Denoiser for something like a tattoo gun, but have had great success with the waves version for getting out some serious ground loop buzz.

The Spectral repair is awesome. You do have to noodle with it sometimes, but I've been shocked at what it can do.

Phil, so you have the full version (the one over $1000)? Can you explain some of the differences between the two versions?

Izotope RX

I use both RX as both standalone and as a plugin. I also find the standalone more useful when dealing with larger problems. A Tattoo pen will probably be a difficult task remove as it does not have a constant pitch. If it's just a short scene, it may be worth the time, but if the show features a tattoo parlor with a lot of dialog, you may have better luck just some good notch filters.

It wasn't that expensive, so maybe there is a version beyond what I have, although I got it when it was first announced and I know there was some discount then. I don't have any other version so I don't know about the diffs. I still like reNOVAtor better for attacking short noises and distortion--I think it is faster and more straightforward, but the Denoiser is pretty interesting. Like all of this type of app., you have to take a deep breath and slow down a bit and concentrate while you use them--they are not as fast at all as a Cedar box.

Thumbs up RTAS mostly

I find Spectral Repair is more useful in standalone mode. Otherwise, I use the RTAS plug-ins.

From RX Manual:
In addition to the base version of RX, an extended application, iZotope RX Advanced, offers even more precise control over RX algorithms as well as including iZotope's critically acclaimed 64-bit SRC sample rate conversion and MBIT+ dither for professionals who want finer control over processing and delivery. RX Advanced Exclusives:
  • MBIT+ Dithering panel with full control over dithering options
  • iZotope 64-bit SRC resampling with a full range of control
  • Advanced manual declicking
  • Multi-resolution declipping
  • Multi-resolution spectral repair modes
  • Advanced Denoiser panel with finer control over the noise reduction process

well, i've received some audio to test RX. i only have
the demo so far...but i assume the full version is basically
the same except i can save. the results aren't too good i'm
afraid. as predicted by those above, the tattoo gun does change
pitches, but the general noise of it is largely in the higher
frequencies. if i get too radical w/ EQ or noise reduction, the dialog
intelligibility goes way down.

so is CEDAR the only answer for major surgery like this? don't you
hate when you bite off a project and then realize you've hosed yourself
by promising good results w/out really knowing if you can deliver?

in fairness, RX does help...but the Hum Remover module might actually
work better than the De-Noiser in the end. we'll see...

That probably is best done with the spectral repair and lots of work if the
scenes are long. Algorithmix might be better though?

An extremely positive vote for the Algorithmix plugins.
As far as I am concerned, the best that money can buy.

Does anyone know, in Izotope RX Advanced, does the graph that illustrates the settings for the SRC resampler show the "passband" or the "transition" response of the conversion?

If it's just dialog with the tattoo noise, using RX should be effective and not too difficult. If there is music in the background or other more dense audio, it will be far more difficult, but achievable. I've done some intense repair using RX, and although it can be time consuming, the end results are rewarding. One thing that helps is to spend time making sure the Spectrogram is set up to optimize your visual feedback. I've found this to ultimately save time and enable you to make more accurate decisions while editing.

yeah i really do love the internet when it works like this.

so i ended up using the crap out of RX's Hum Remover. it helped
quite a bit without being too destructive but i still had lots
of tattoo gun noise in the tracks. the director and the local
PBS station guy said they were impressed with the improvement
with the dialog...so i guess that's something.

thanks to all for the attention to this topic. i hope never
to have to work w/ tattoo shop dialog again!

cheers,
marty.

Hey marty,
so you got something usefull out of RX Hum removal? when I tried the results were too phasey and I got better results with Waves Q10. maybe I did something wrong. You got the trick?
RX Declipper is also not very satisfying, I found those in Waves and Sony restoration (discontinued) better.
For the other RX modules, I don't remeber how I managed to do my job before I had them...

hi Felix-

i actually don't own Q10, but i've heard it's great for this kind of thing.
believe me, i battled RX in every mode (noise reduction, etc) it had, and
it still wasn't gorgeous, but yeah, i got some decent results w/ the Hum Remover.
i still had plenty of noise in the dialog, but it was more palletable after the RX.

if i have time over the holidays, i'll post a pre and post clip so you can hear it. believe
me, i won't win an Academy Award for my work, but...

happy holidays posties,
m.

Rather than start a new thread...

Rather than start a new one, I'll revive an old one with the appropriate title. Another 'miracle cure' for me today!



Finishing up a student project, can't get in touch with the composer who delivered stereo files and there is distortion/crackle in the tracks (see attached .aif for a short example).

So on a whim with my remaining time I tried iZo Declicker, Declipper, waves X-Click, X-Crackle but no dice. Made some worse even, not surprisingly.

Then "Hmm, I wonder if it shows up in Spectral Repair?"



As the kids say--- "Boo-yaaaa!"

Another notch in the iZotope RX Spectral Repair belt. I'm just bummed that I have to do the crackles individually. Should only be about an hour...

How would spectral repair do on clothing rustle? Sometimes I get wardrobe that just can't be tamed and was considering getting this to clean up the random rustle.

You'd just have to try it to find out... each situation is different.

I just used iZotope RX De-Clicker to help with some wireless lav rustles/clothing rustle and it helped a good deal.

But, as they say, YMMV.

Izotope RX

I recently finished a feature film mix and ended up using RX broadband, Cedar dns 2000, McDsp NF575 and ML4000.

Spectralrepair worked for noise appearing in the dialog but not when the noise had much of the dialog freq in it. Often it works best on sudde. Dynamics sounds.

NF576 is my Q10.

And ML4000 works as a my CAT43, comp and desser.

Cool

I don't have much to add on how to use RX, as that's been covered well here.

But I will add that RX was very useful on a series of loop libraries I've done recently.

It was pretty indispensable for removing hum on B3s, guitar noise, etc. and helped a lot to clean up microphone bleed, etc.

I tend to use it standalone, in combination with AudioFinder, as I use AudioFinder as a hub for my editors, etc.
