Izotope RX Voice De-noise In Depth - Remove Room Noise

[@gandriatiger]

Finally, a professional who shows us in a step-by-step, easy-to-understand way how to use RX tools. Thank you!!! I have been hoping for years that Izotope would do this, and have given them customer feedback to this effect (e.g. like starting an "RX Academy"). There is a whole universe of video editors out there who know little about audio editing and need this knowledge! To Curtis: Would you also be so kind to do a short video on the Spectral Denoise plug in? (I have the RX9 plug in embedded in FCPX). Thanks again.

[@curtisjudd]

Thanks Richard. Will try to include more RX videos.

[@alantuttphotography]

I love this plugin, and probably use it more than I should, most often with default settings. I'll need to try the gentle setting a few times and see if I notice the difference you're talking about here. When I have too much noise for this plugin, I'll use the spectral denoise plugin with a learning pass to get a noise profile. Amazing what these plugins can do!

Thank you very much Curtis - your explanations are super clear for non-experts. Please could you consider a video on removing breath sounds - maybe using the Rx de-Breath - but also using tools available in standard apps (I use FCP), such as a Noise Gate. I have played with noise gates and they seem to help with my in-breaths (I had pneumonia a few years ago, so the sound is prominent). But I am not an expert. I mostly remove breath sounds by manually ducking them in FCP.

Hello Curtis. This talk was so clear, cordial and helpful! Five months later and I'm looking at denoising 200-plus CDs of informal conversation and talks, some with horrendous noise, captured on cheap casette recorders, late 1970s and early 1980s. I have RX7 Standard and, now, RX Elements Suite with RX8, Ozone, Nectar, and Neutron Elements. I'll be working on an M1 Mac Mini. Nice to know I can do a couple of passes. I wonder if Voice De-Noise or Spectral Noise Reduction will be the best for the really ugly tracks.

[@curtisjudd]

Hi Amanda, thanks. Generally, Spectral De-Noise can remove more noise in the situations where it works well. Best to experiment with it first. But I often find that Voice De-noise works great on spoken word audio.

[@AnandaGarden]

Thanks so much for responding. That really helped me understand when to use each module. Very important, with so many files to denoise. Of course, I'll be testing as you suggested, and maybe set up a module chain to run as a first pass.

[@RavikantRai21490]

In clips where we do not have just noise and there's constantly ONLY sound, adaptive mode itself does a pretty great job. Because if you do not have just noise, it is hard to properly utilize learn, or at all. So I find in those cases either adaptive or manually tweaking it myself and listening to the sound leads to decent results.

[@curtisjudd]

[@TwinePoodle]

Hey Curtis ..thanks for starting this series. Been eyeing the iZotope plugins for some time...saving up. Definitely looking forward to any help with de-reverb. My home studio is in good shape, but for a freelance gig I've been working on, we've been filming in a large garage, and while sound blankets have helped, there's still more reverb than I would like...a light reduction would be helpful. Using a shotgun mic about 6 inches from the talent. I know something like a short condenser would also probably help, but for now, Im limited to what I have. Anyway, a real lengthy way of saying thanks! Haha.

[@curtisjudd]

Thanks!

[@realfingertrouble]

This was really great - and wish I'd seen this video when I was struggling with De-Noise in Elements years ago! And your mouth click one - I came to the same opinion - and also had CPU issues with running DeClick or some of the other plugins bar Breath Control - so I have that in the stack just reducing those, and then pre-process the vocals with Mouth DeClick - and your settings were pretty much what I've been using, which is reassuring! The one that really confuses me now, and I tend to just tweak existing presets is the Spectral De-Noise in RX Standard. It's like the bridge on Star Trek that plugin! But the quality is so much better I feel, even though there is more processing overheard? I just batch the podcast vocals in the background. So a video on RX Spectral De-Noise would be really useful.

[@WineWorldTV]

A bit late in seeing this one, I'm a big fan of RX. I've been using RX 8 Standard for a while now. I did upgrade to 9, but I haven't really done any recordings recently to need it. Anyway, I've got a nice batch setup that includes this module. Slightly different settings, but achieve good results. My two main issues are AC sound that may or may not be present and, funny enough, the potential of the dishwasher going in the background. I literally use the dining room table and record late at night. But the dishwasher will frequently be started before I'm planning on doing a session. This module effectively eliminates that sound. Even at its loudest point. The modules I use, in order, are Mixing (the Zoom H1 is mono for me), De-clip (just in case), De-click, Voice De-Noise, De-reverb (just to flatten things out a bit more), EQ, and Loudness Control. Works really well as a batch. I just now have to import my presets into RX 9 when the time comes when I create more content. Always great videos and you explain things very clearly!

Thanks for another great video, Curtis. You mention that in can be used in real time for streaming but I can't find much info out there on how that would work. What is the basic set up? Also have you tested the music mode? I'm wondering how well it would work outside of vocal applications, say on the violin.

[@curtisjudd]

Hi Clayton. To use any plugins during a livestream, you would need a host app which can run VST, VST3, AAX, or AU plugins. I don't know whether you're using Windows or Mac, but on Mac, I'd probably use Audio Hijack as the host app. I haven't used the plugin on music recordings yet.

[@Hzuuuu]

It is possible. On Windows, ASIO Link Pro is the best. My setup is REAPER > ASIO Link Pro as output devices > set the ASIO Link Pro's input devices in Windows as default properly > OBS/Discord/games/etc. Then make sure the programs are using the ASIO Link Pro's input devices which it has installed into Windows. I use REAPER because sometimes I need to record my own voices while livestreaming, so it's more of an all in one solution.

Follow up comment: I've been experimenting since you posted this video and it works great with music. I am now able to route Logic into Zoom via blackhole which is fantastic as the zoom noise filters need to be disabled when playing live music. I've been teaching fiddle and occasionally performing concerts on zoom since the beginning of the pandemic and this has really cleaned up the audio!

Nice job on this video. I have been using RX8 and RX10 now for a while, and have been trying to learn on my own. This video really helps me understand how to take care of noise.

Have you found any others really useful? Or maybe I'm using them wrong? Thanks!

[@LEYGSL]

This tutorial was exactly what I needed so I subbed, Thanks! Also when you used the EQ, what were the reasons behind specifically using a 48 dB/octave cut and at 80Hz?

[@curtisjudd]

I chose that because it cut out the low frequency rumble without affecting the dialogue. I do that because people who play back the audio on speakers (often with a sub woofer) which can play back those frequencies won't have a nasty bass rumble surprise.

[@d0jima]

Hey, Curtis, huge fan of your channel. Just had a quick question for you. Do you typically always use some form of noise reduction regardless of the gear you're using? Thanks.

No, only when needed. I prefer to control the noise in the room so I don’t have to resort to post noise reduction. On location, where I don’t have as much control, yes, I often have to do a light pass.

Hi Curtis thanks for your video I recently bought rx 10 standard and not seemingly to get good results with a hiss that comes trailing with my vocal signal. Seems simple enough but not easy to find that tradeoff of losing character. Your video gave me some good ideas to try before the next attempt. Including running it through multiple passes. Maybe I had imagined it differently in in my head but it's just kind of a form of advanced EQ'? For some reason I thought it would learn the noiseflour and then pick out all those specks and particles of sound lol... maybe i'm just dischenchanted because I don't understandfully how it works and it's not working for me :) Thanks for making this video!

[@curtisjudd]

Technically, this is a bunch of noise gates working at different frequencies. There is a manual mode where you can have it learn the noise pattern and then apply it.

Hi Curtis, great video thanks for putting in the time to share it! I have a question: When do you NOT use adaptive mode? ie. what kind of problems are best solved with the non-adaptive setting? I process a 3 track podcast every week where the tracks are 1.5-2.5hrs long each. I have found that non-adaptive gives me better results considering that I am applying the de-noise over such a wide swath of audio with loud and quiet moments. Thanks in advance!

[@curtisjudd]

Hi Chad, adaptive mode works pretty well in most situations, but I have encountered one or two where it left some artifacts that sounded like it was obviously changing it's configuration mid-audio-clip. It is usually pretty reliable, though. So I don't hesitate to use adaptive mode most of the time and just keep an ear out for any odd transitions it may leave. But for long-form content like what you describe, the manual "Learn" mode is probably safer.

[@curtisjudd]

Hi Magnus, I'm sorry, I don't understand the question. In cases where you don't have a clear section of only noise, the adaptive mode can work nicely. Also, if the noise changes a bit throughout the clip, the adaptive mode can be helpful. In some cases, however, the adaptive mode can make some rather obvious changes and the manual/learn mode may be preferred. You have to experiment with each audio clip too find which works best for that particular clip.

What is the difference between Voice De-noise and Dialogue Isolate? Thank you for the great tutorials.

[@curtisjudd]

Voice De-noise only removes noise. Dialogue Isolate allows you to independently tell the plugin how much ambient sound to keep in the recording. This may sound counter-intuitive, but in film mixing, one often has to match different microphones and having the ability to dial in exactly how much of the ambient sound you remove and how much you keep is really helpful.

In that case what level should I aim to bring the noise floor to? I know -60dB would be impossible without many artifacts... And should I make my ambiance tracks a little louder than usual to try to hide/mask the noise?

In other words, does it expand (gentle) or narrow (surgical) the bandwidth over which the input is integrated to obtain the control signal for each individual gate, such that neighboring gates will tend to behave similarly (since a loud sound at a single frequency will impact multiple adjacent bands/gates instead of just the one that contains it). At any rate that's what I would instinctively try if somebody asked me to build one of these. I'm surprised that applying multiple rounds of the algorithm would perform better than a single, stronger round. Back when I did image- and signal-processing we considered that sort of thing as an indicator that the filter was deficient in how it implements the stronger setting and needed to be fixed.

I'm not sure and Izotope doesn't disclose that level of detail, unfortunately.

I have an XAir that all my audio feeds in to and I want to use this de-noise for live streams. Not sure how to do that. I presume I need to use a PC and pass the XAir input into USB send, through this VST plugin then out to another XLR output so I can send to my recorder? Any guides on doing this with XAir?

[@curtisjudd]

I've not done this but I think you have the right idea.

[@RetroSix]

@@curtisjudd think I've figured it out. Xair into PC using USB send and return to basically loop the inputs through PC first. Then use a VST Host I've used Gig Performer and pass Xair USB in to the rack then the VST plugin of Izotope then out to XAir USB return

New subscriber BTW (really enjoy your presentations). Q: can i use this program for cleaning up old cassette tapes (I have about 100 i want to digitize). Is it over the top for that, is there a program you recommend? Thank you.

[@curtisjudd]

The elements version would be good for that. But you first have to capture the audio and digitize it. This app doesn't do that.

[@monkeybegood]

@@curtisjudd Thank you i have a way to digitize them, just want to take the hiss and clean up vocals etc. thank you Sir.

[@kengoodwin459]

I tend to use the Spectral De-noise more than Voice De-noise. Have you compared the two? I think Voice Denoise is a little too rough.

[@curtisjudd]

Will cover Spectral De-noise soon.

[@michaelhalloran3948]

Will this plugin possibly help remove an audible clicking sound caused by an artificial heart valve when using a wireless or lav mic?

[@curtisjudd]

It isn’t as good at discontinuous sounds like that. Spectral de-noise would be a better choice there.

[@BrannonNod]

Curtis I need your help please... I just picked up a Zoom F8n..Love it so far. I'm using a LCT 440 Pure mic..I use to use that mic with the Zoom H5. I also use Adobe Premiere Pro so I've always used some filters in my timeline to get rid of the background noise. And never had any issues when I cut my talking head shots. But now when I use the F8n and use the filters the sound is perfect until I start cutting at the beginning of each of cut it muffels the sound and then returns to normal after a few seconds? If I don't use any Adobe filters I can cut all day long and the sound stays the same. But then I have the background hiss? Love what you do 🙏

[@curtisjudd]

Hmm, sounds like maybe the effects/plugins you’re using are the issue. Would need the details on what you’re using there. Consider adding them back one at a time to see which one is creating the issue.

[@BrannonNod]

@@curtisjudd thank you Curtis.. Upon further research turns out it's a Adobe Premiere Pro glitch with the Denoise plugin

[@curtisjudd]

@@BrannonNod Nice work sorting that out.

[@adimology]

What's the difference between using Voice De-Noise and Spectral Denoise if you learn from the self-noise (room noise) and apply it to all waveforms?

[@curtisjudd]

Standby, we’ll have another episode on Spectral De-noise. But one obvious difference is that Spectral De-noise is not as practical for live use with its much higher latency.

[@adimology]

Have you tried Nvidia's Voice function in Nvidia Broadcast? I was stunned at how well it works.

[@curtisjudd]

No, I don't have an nVidia card, but the tests I heard varied from ok to sounding like the person was talking into a pillow. But I think that's just because they pushed the settings too hard. Like most things, using just a little bit usually works better. Also, RTX Voice also has adds a lot of latency last I heard - tens of ms - which can be problematic.

[@OneStepToday]

for live voice work, spectral denoise is better or this voice denoise?

[@curtisjudd]

I’d use voice denoise first.

[@nursemary5780]

This might be a dumb question, but are you are able to use this software in just IzotopeRX and save it to use in another video editing software (I use Wondershare Filmora) for pairing with the video? Or do you need this to use in the actual editing software like Audacity and I can't use in Wondershare? I am 100% new to this LOL

[@curtisjudd]

Yes, in fact, that's usually what I do - clean the audio in RX first, then save it and sync the audio up to my video in Final Cut Pro.

[@nyambe]

Very helpful!!

[@curtisjudd]

Thanks.

[@harrij.9542]

I own the elements version and now wondering if I could use it in OBS to clean up some live audio...

[@curtisjudd]

Yes, assuming that OBS can host VST plugins?

@@curtisjudd i tested it today and works great! It does support Vst2-plugins.

[@mamandapanda185]

Curtis, do you think this could work for sibilance attenuation while recording and, if so, would you need multiple de-noise-rs in the FX chain to pinpoint troublesome sibilance ranges (i.e. 6-7khz for s's and 3.5 - 4.5 for c's)?

[@curtisjudd]

Mmm, I’d generally reach for a de-esser plugin first.

[@mamandapanda185]

@@curtisjudd Yes I've been on a long journey trying to find one that works for me post recording. I even bought Soothe 2 a year ago, which some say is the best available, only I cannot find instruction on how to tweak it beyond its sibilance presets. RX's seems to not work as well. I would just like a different mouth.

[@curtisjudd]

​@@mamandapanda185 I can't help much with the mouth. Maybe try a different de-esser if you're finding the RX de-ess module isn't working well for you. Maybe try fabfilters?

[@lawnjustice5742]

So in your opinion do you thing that noise access plug in on the mix pre is better or worse this this program in achieving the end goal of reducing noise.

[@curtisjudd]

NoiseAssist is a good choice if doing live sound with the MixPre. Otherwise, I prefer to use Izotope RX in post.

[@Katafod]

great! thank you

You're most welcome.
