Izotope RX2 Tutorials for Post Production

Just doing some cross-posting from my website:

I decided to put these two tutorials together to share some simple tricks that I use in Izotope RX2. They’re nothing overly complex, but they are kind of unique….and handy to boot. I just thought I’d share them and hope you find them useful.

The other video can be viewed in this post.


  1. It is so inconvenient that RX2 doesn’t has a customizable crossfade function when you copy and paste time/frequency regions and any crossfade capability in general. Yes, there is no clips when I paste a region, but I can’t replace large sections because I can’t create the smooth transition. It’s really strange.

    • @Conant – well, it’s not all that surprising, considering that it’s not designed to be an editing program. while i would welcome it’s inclusion, i’m happy to see them focusing on the noise reduction tools and algorithms.

  2. Hey Shaun,

    Thanks for posting the vids! This is something I’ve been thinking about the last couple of weeks. I reckon it would be good to find a place to share all our tips/techniques in one place. Maybe an SSD topic?

    Been tweeting with a couple of soundies regarding RX techniques and would find it useful to find somewhere to pool all our knowledge (vids, etc included).

    Seems almost one of those ‘black arts’ when it comes to noise reduction at times lol

    Any plans for further modules such as Denoiser?

    Keep up the hard work!

    • Sure, a thread sounds like the perfect place to do that. I don’t have any plans for other tutorials at the moment, though I did start thinking about it after doing these two. These were just two tricks that I had developed that noone I was speaking with had tried out/discovered yet. I’ll think about it, and will do one if I feel I have anything unique to share.

  3. hey shaun,

    this is rad, thanks so much for sharing. i’m new to RX2 but am i nuts to want a preview on that attenuate section of SR before processing? is that function hidden somewhere?

    thanks again!


    • i don’t think you’re nuts, katie. you can at least undo/redo to compare and make sure you’re happy with the results. it’s what i did in the video.

  4. Great stuff Shaun! Definitely going to use these techniques soon.

  5. Thanks Shaun, great tips to add to the toolbox!

  6. iZotope does crossfade most editing operations. The length of this crossfade is given in Preferences > Misc > Selection feathering.

  7. I have been using isotope for several year and it is my #1 tool.

  8. Hi Shaun, i wonder if you can help me. I am currently restoring the audio ripped from an acetate. The track is a dance music track and the intro has been easy to clean using spectral repair “replace” on the areas where there are scuffing sounds (2 per revolution). The problem i have is after the track has dropped the scuffs continue but the snare hits at the same point so i am struggling to repair the scuff without effecting the snare. Have you dealt with similar? is there a way to take a clean snare and drop it in place of the scuffed one?

    Hope that makes some sense.

    • Hmm…that is difficult. It’s nigh impossible to remove noise when it occupies the same spectrum as something you’re trying to preserve. Your idea of replacing the dirty snare with a clean one could work. The first thing you would want to do is process the clean snare to match the sound of the existing (EQ, compression, reverb, etc…I’m guessing the original snare sound didn’t go in there unprocessed). Drag those new snare hits and the original music into your DAW, leave a couple of seconds of silence between the track and those new hits, and bounce both out together into a single file. You can’t copy spectra from one file to another in RX2 (at least, not to my knowledge), but this way you can access them for the copy/paste procedure…since they’re already in the same file.

      After you copy the snare hit (use the “time” selection tool), use the lasso tool to select the one you want to replace, right-click in the selection, and use “paste special” > “to selection.” I imagine this will run the risk that it may overwrite information related to other instrumentation, but you’ll have to judge for yourself whether or not it’s objectionable. I’ll be interested to know if this works for you, so let us know if you try it.
