Izotope RX 9 Dynamic De-hum

[@RolandsBriedis]

Thanks! Would love to see more RX 9 advanced tutorials!

[@curtisjudd]

Plan on it!

[@hypnosecoachinghombach7517]

The dynamic de-hum is one of the modules I most frequently use. I've even been able to rescue about 40 podcast episodes that were ruined by a broken lavaliere mike. With dynamic de-hum it was a work of minutes to remove the hum. It was this video and the others you made that inspired me last November to buy RX.

[@curtisjudd]

Glad RX is helping you!

[@AndyMaherVoicePro]

In RX8 I've been using guitar De-Noise's "Amp" component to achieve comparable results. I always found the De-Hum to have ringing like you have shown here. Now I'm keen to try the new Dynamic De-Hum!

[@curtisjudd]

👍

[@AliMoeeny]

This looks like magic

[@curtisjudd]

Pretty close!

[@danielesainidesign]

This module is really good ;)

[@curtisjudd]

Indeed!

[@ErickMcNerney]

Are you still able to isolate the hum so that you can hear what is removed from the sound?

[@curtisjudd]

Yes

[@SeanSeebran]

Hey Curtis, great video as always. I was just wandering if you will be making a video on the new Deity Pocket Wireless system? I would really like to hear your opinion on it, especially compared to the Rode Wireless Go ll.

[@curtisjudd]

Nothing in the plans yet, but possibly down the line.

[@SeanSeebran]

@@curtisjudd Thanks for the quick reply buddy, I really appreciate it. Keep up the great work, and stay safe out there.

[@FertilityfromtheSoul]

Have you compared this to the new Rx10 version? Wondering if there are significant differences. Also, do you have an idea how this differs from voice denoise? Thanks for these very detailed and clear videos! I'm looking forward to watching more of your videos so that I can fine tune my meditation recordings.

[@curtisjudd]

Very few changes in RX10 except the de-hum now has a dynamic mode so you don’t have to “learn” first.

[@FertilityfromtheSoul]

@@curtisjudd thank you! And is there much difference between de-hum and voice de-noise? Also, are you available for private consultations....like if I wanted some one-on-one guidance on fine tuning the sound quality on my recordings? i use logic pro, and I have the RX9 Standard pack as well as JJP vocals for plugins.

[@curtisjudd]

@@FertilityfromtheSoul Yes, absolutely. De-noise is for broadband noise while de-hum is specifically for hums which often have a strong fundamental at 50 or 60Hz, or some multiple of that and then several harmonics at higher frequencies. At the moment, my day job keeps me so busy that I cannot consult, but perhaps in the future that will change.

[@MrJetanaipe]

Hi Curtis, you should review Absentia DX. It removes these hums with literally one click. And it also features batch processing to process the whole dailies.

[@curtisjudd]

Thanks

[@sozbob]

Nice overview Curtis, whilst not a magic bullet the new De-hum module seems like a big improvement. Would be great if you could take a look at the new Dialogue Isolate module too. So far have found the new algorithm to be pretty much unusable on everything I've tried it with (loads of high pitched squealing artifacts). So would be really interested to see if I'm doing something wrong / others are having good results.

[@curtisjudd]

Yes, was just working with the new Dialogue Isolate this morning. It seems to work best with discontinuous noise that is NOT broadband which, when I think about it, makes sense. It was not able to remove footsteps in the background of a dialogue take, but was able to remove most of a mobile text notification sound. More to come on that.

[@sozbob]

@@curtisjudd Thanks Curtis, yes definitely seem to need to be more selective compared to legacy algorithm. I'm finding breath noises etc send it doing some strange things. But sure it will come in handy for some precise targeted work like the text notification sound.

[@robertniessner554]

I am having great results with the new Dialog Isolate. But I always prepare the audio with a slight spectral denoise beforehand.

[@patentjt]

also Curtis, i find the spectral noise feature to do the same thing as the de-hum. What would you use the de-hum vs the spectral noise features? thx and great video

[@curtisjudd]

Hums are quite distinct. They'll have very strong fundamental frequencies and harmonics. Noise isn't usually the same. First thing to do is figure out whether you have a hum, just general noise, or both. Then I'd tackle the hum first, then the noise.

[@DavidKfilmmaker]

Hey Curtis. Awesome as always. My question is comparing sound designs hum plug in vs rx9’s dehum. I have rx but have been curious about the sound design plug in since inception.

[@curtisjudd]

Hi David, I haven’t heard of the Sound Designs Hum plugin. Will keep my eyes open for that and have a look.

[@DavidKfilmmaker]

@@curtisjudd i had it wrong. It’s mixassist. You did a video about it. Thought they address the same problem. Maybe not.

[@NyoMurdi]

Hi Curtis, have you covered Absentia DX? Not a specific plugin or editor but a very reliable tool!

[@curtisjudd]

No, haven't heard of it.

[@chainshot]

@curtisjudd i would love love love to see a proper workflow for a casual production day - loading in the complete footage in premiere and then batching those through to rx9 somehow. Complete adjustments, from removing stuff, to refining the sound overall - maybe even how to get a proper preset build to fire up everytime. I cant work through like each individual interview clip, going back and fourth every single time...since there are like 30-50 clips/cut... could you showcase a real world scenario on a bigger scale than this micro example?

[@curtisjudd]

Yes, but not in Premiere since I don't use Premiere. I'd be more likely to show it in Audition or Resolve.

[@chainshot]

@@curtisjudd thanks, i think rx9 still doesnt work in Premiere... So the roundteip would be: Premiere to Auditon anyways... if its just a click like open timeline in Addition. Maybe you could include that.

[@curtisjudd]

@@chainshot The RX plugins work in Premiere, but the round-trip to the RX editor is easier via Audition.

[@patentjt]

Workflow wise, do you find it easier to use RX9 as a stand alone program or as an insert inside of a DAW?

[@curtisjudd]

I would prefer to stay in the DAW, but some of the RX modules are only available in the RX Audio Editor. These are generally modules which have to process audio offline.

[@WaltherLigtvoet]

Did they change the package? In RX8 Elements De-hum is available....

[@curtisjudd]

Not sure.

[@theenemyoftruth8552]

Hi, I'm new to RX and am using it to clean up vinyl recordings. On my recordings I see and hear a bit of buzz/hum at the beginning but when the needle drops I don't see or it. So, I was wondering should I de-hum the whole song or just the bit at the beginning, in which case I'd probably just cut it out. I'm not sure if the needle drop cancels it out?

[@curtisjudd]

Yes, I'd only apply it to the bits that need it and if that means only before the needle drops, then yes, I'd just cut that part altogether.

[@theenemyoftruth8552]

@@curtisjudd Thank you, Curtis for you're reply. Yes, that makes sense to me. It's very tempting to go crazy to clean up audio that probably doesn't need it. Same with the clicks, if I don't see or here them I'm thinking, don't do the whole song, but yes, it's tempting as a newbie. Thanks again, now I can move on. 🙂

[@magnusgotander4064]

Futher on after the de-hum, would you try the de-crackle afterwords, or what would be the most probable? Helpt my collegue recently with exactly this problem but with the earlier version of Izotope. He had been in a aircondition compressor room and I got it "good eanugh" except a little bit to much cut in the dynamic with just de-hum and de-crackle. Hadn't the latest version then, but now 🤗

[@curtisjudd]

I'd probably go to spectral or dialogue de-noise next to pull down the fan noise a bit.

[@magnusgotander3954]

@@curtisjudd Sorry, my bad, now I remember, it really was spectral and dialogue denoise that I used but I tried or even saved it with the de-crackle as well. I will picup and try with a new version now when I have the new post/Iz.nr.9. Thanks. M

[@G7sus4chord]

When you select the "Learn" feature, it seems as if it takes a quick snapshot of the seconds of audio you've selected. When I do it, it just it just listens to the audio starting wherever the cursor it. Am I not selecting it properly? Different DAW (I use Studio One)? Different version (I have RX 9 Standard)?

[@curtisjudd]

I'm using the RX Audio Editor in this demonstration. I believe you may have to round trip over to the the RX Audio Editor to use the learn feature.

[@AllenCavedo]

Nice demo of an amazing new feature. So glad I don’t do any post audio work 😆

[@curtisjudd]

Hahaha! Thanks Allen. As long as you deliver amazing, clean tracks to post. 🙃

[@ProducerWannabe]

Thank you for the video, Curtis! How about removing RF interference? And would you compare the RX 9 de-Hum with the Adobe Audition’s noise reduction process in the future video?

[@curtisjudd]

Yes, potentially helpful for RF interference as well. Noise reduction and de-hum are really two different things. I've generally not found de-noisers to do well with genuine hum.

[@ProducerWannabe]

@@curtisjudd thanks for the answer!

[@mychess5821]

Hey Curtis. Which mic is the best for both outdoor and indoor movies and which is the best audio recorder

[@curtisjudd]

That depends on so many things. From what I can tell, there isn’t one mic to rule them all.

[@mychess5821]

@@curtisjudd Then which mic do movies use? And which is the best audio recorder? Which one do u use the most?

[@curtisjudd]

@@mychess5821 Lots of different microphones. Sanken CS3e, Sennheiser MKH416, MKH50, Schoeps CMC641, CMIT 5U, DPA 4017B, and lots and lots of others. Also, they use a ton of different lavalier microphones.

[@vincentpourchaire9918]

I would like know if we could work in multitrack whith RX 9 standart? By the way, thank you for your vidéo.

[@curtisjudd]

No, it isn't a DAW. It can open and process 6 channel poly wave files, but you cannot treat each channel separately.

[@vincentpourchaire9918]

@@curtisjudd Thanks for your answer. I buy it. If i understand correctly, I can open 6 channel and treat them together. It seems good for my works.

[@robertniessner554]

@@curtisjudd Curtis, that is not correct. You can select / deselect individual channels and then treat them like they are seperated.

[@curtisjudd]

@@robertniessner554 I stand corrected. Thanks Robert. I think it is still important for people to understand that the RX Audio Editor is NOT the same as multitrack DAW apps. I get questions all the time from video editors about whether they can do something like a film mix in RX Audio Editor.

[@toby9815]

Thanks for the video. Would this work on an instrument track, say on an acoustic or electric guitar track?

Hey :) what headphones do you have on in the thumbnail, I know it makes no difference, just curious. I thought dt1990's but they don't look the same

Not yet. I need a 5.1 playback system first.

[@huyked]

That's very nice. Thank you, Curtis. In regards to wind noise, what has been your experience? I would guess it's harder to remove because the pattern is not much of a pattern, but more random?

[@renartsk]

This program is magic, de-wind cannot make you sound like in studio, but it will make it enjoyable enough, that it's not disturbing.

[@huyked]

@@renartsk Oh! It also has de-wind? Nice! Thank you for letting me know! I'll have to search out for examples.

[@renartsk]

@@huyked Yeah, it does. It also has de-clip, which saved my ass on one occasion. Wind hitting the headphones was so strong, that I couldn't hear that I was clipping (mic turned up, receiver down, so mic levels were not a pointer). Really one of the best purchases one could have if mistakes have been made

[@huyked]

@@renartsk Thank you for sharing your experience and the confirmation. If you have any unlisted examples of before and after (final edit), I'd love to see it what you mentioned. Cheers!

[@donsalluste7296]

I love Izotope's products but to be honest, their de-hum is quite poor in quality. I use different plugins which take 1 sec to learn and totally cut off the hum.

[@curtisjudd]

Interesting, I found the new dynamic de-hum in RX9 advanced to work really well. Which other plugins do you use?

[@donsalluste7296]

@@curtisjudd As I see in your video, there's still some remaining hum after rendering. I use Brusfri plugin to get rid of that kind of noise and this is quite amazing. Maybe needs a slight EQ adjustment after rendering.

I'm impressed by de-hum, but the rest of RX9 (especially Standard version), however, is a disappointment :( Anyway, very good test, Curtis!

Thanks, Rutterkin.

Upgraded to 9, but havent needed the de-hum yet
