Thanks Chris!

[@FoodTechLife]

Good info on the part where you have to consider how much room you have left for loudness and using compression as well. I don't have the full iZotope tools because $$$ but I purchased RX Elements for like $10 when B&H had a sale. Unfortunately that still doesn't have the loudness part in it (or breath and mouth clicks). I just got it for the denoise. What does have a nice tool for loudness is iZotope Ozone 9 Elements. You can tell it to target -16 LUFS and set a maximum peak. So that's what I do! Best of all Sweetwater had a campaing where they were giving it out for free after signing up with them.

[@curtisjudd]

Thanks - good to know that Ozone Elements can get the job done!

[@Thomas.Steinborn]

Thank you, that is very helpful!! FYI: I just discovered you can get the audio analysis in Resolve without listening through the whole thing as well: right-click the audio track in the sound editor and there you can choose 'analyse audio levels'.

[@curtisjudd]

Thanks Thomas. Is it possible to analyze the levels for the entire mix or is that just for the selected clip?

[@Thomas.Steinborn]

@@curtisjudd I don't know. But I did right-click on the clip in order to get this option, so I guess that was clip-specific.I didn't yet try to get a reading for an entire mix.

[@RussJohnsConnects]

Accessing RX from resolve has been an EPIC discovery. I have several recordings that are at the extreme ends of the range as far as db I need to find a few more RX lessons that address the workflow for leveling out the difference. Audience interviews and different mics can create a variety of levels. :) Fairlight is getting better and I like working in RX a bit more.

Interesting - because 99% of the music on KZbin is 3 LUFS louder than this video. Hahaha! I'm still dabbling with Fairlight. Version 16 is better than ever but I'm still getting a lot of crashes when mixing a short film with 25+ audio tracks. My computer is plenty powerful to handle that and more so I'm assuming that's a Resolve issue. But yes, we'll probably have more Fairlight content in the future as it stabilizes and matures.

[@UnusualAudio]

If all you have is RX Elements, you can do exactly the same workflow. Instead of setting the slider and hitting Render in Loudness Control you can just open up Waveform Stats, calculate the difference between integrated loudness and the target yourself and then click Gain and enter it there.

[@curtisjudd]

Yes, being sure to do your maths and make sure you won’t clip or heavily limit the audio.

[@aussernllc]

I'm sure you've answered these questions a million times, but if you have one more in you: Link to sound proofing Link to sound treatment My office has greater than -60db noise floor for 250hz on down Above 250hz, the noise floor is -60db to -100db with the microphone, XLR cable, and audio interface in the supply line. Not sure when it's time to replace the microphone or anything else. Hoping treating the room is where i need to start. High pass filter at 80hz, compression, noise reduction at a minimum.

[@curtisjudd]

[@fotouhi]

Thanks very much for taking the time to upload these great videos. This video was educational - and timely - as it outlines a complex process in simple steps. One note though: I got told that it'd be better to apply target loudness normalization for the dialogoue track(s) not the entire mix. That approach would make sense to me because the music, effects and ... are built around the dialogue anyway. Your thoughts?

[@dominey]

I was wondering the same. I only apply loudness to dialogue because music is often times quite loud and compressed already.

[@curtisjudd]

You’ll still generally want to do a final loudness check. Often music is substantially louder than dialogue and especially in cases wher e you have not music and dialogue you need to measure the overall loudness if the goal is to produce consistency.

[@curtisjudd]

Thanks Giancarlo. After all the crashes I've experienced over the last couple of weeks, I think I'll be heading back to FCPX and learning how to round-trip to Logic.

[@GiancarloBiondi]

@@curtisjudd Davinci is great for color correction / grading but I find FCPX unbeatable for editing (I don't like Premiere). According to some professionals, Logic is exceptional for working with music but not so great for editing the audio section of a video where Pro tools reigns supreme: in my modest experience I am happy with Logic even if you have to adopt different precautions in the workflow (I will do a video about it .. but in Italian though); I hope Apple makes this workflow (XML from FCPX to Logic and vice versa) better.

[@davidhasbrouck7948]

Another way to do this in rx and DaVinci is to just do the round trip with just dialogue/VO track and normalize it to - 18db. And then bring it back I to DaVinci and use the eq and faders in the music and effects tracks to target - 16. This works well because I often find myself using RX for other things in the voice so I only have one round trip.

[@curtisjudd]

Yes, and I would suggest a final loudness check to make sure the final mix sits where it should. But yes, that should get you very close in most cases.

[@davidhasbrouck7948]

I do the final loudness check in resolve using the loudness line graph below the master track. That way I have a visual of loudness over time. I just run it while doing my final check before rendering. If there is an issue I can see where and then fix that part and spot check it.

[@kugelfunk]

Thanks for the video. Just what I've been dabbling with the past couple of days while finalising an online course. Btw great to see some Resolve examples. I do it a little differently (apart from the fact that I don't own the big version of RX). Namely I try to avoid compression on the full mix. The reason being that I am using stock music which was already heavily compressed by the composer, and I don't want to compress that even further. Instead I add Ozone Limiter (set to -1.1dB True Peak) and Youlean Loudness meter (with KZbin preset) to the mixbus. Then I increase the level in Resolve (using BX Masterdesk as a glorified master fader) until Youlean shows me I am between -15 and -14dB (recommended for KZbin). Finally I check how the aforementioned music track is doing LUFS-wise when it is playing at full level. Usually I have to pull it's level back until Youelean gets below -14dB again. And lastly I drag the final export on to the standalone Youlean meter app which calculates a LUFS curve chart for the entire video plus indicating any Peaks above -1dB (YT setting) in case there are any.

[@curtisjudd]

Thanks for the insights Heiner. I find that most popular music is already HEAVILY compressed as well. What that usually means is that I have to attenuate it quite a lot to get it sounding right with the dialogue and then it basically never gets any further compression when I work on the final bounce/mix because its transients already leave plenty of headroom.

[@keithsanborn8508]

Good. Now what about Film applications? You wouldn't typically compress them as much. Would you do loudness control in the same way?

[@curtisjudd]

Yes, and probably target -24 LUFS.

[@dannypgrizzle]

I was super excited when you announced this video, but even though I have a copy of iZotope RX8 Advanced, and despite decades of reading everything about audio production, I feel helpless to grasp how to use these advanced tools successfully. It seems impossible to be self-taught on this topic. I'm desperate to learn these tools, but just cannot figure out how to approach the task.

[@curtisjudd]

Hi Danny, I'm hoping to make a course to cover this in more detail. But the main idea here is just using compression to make enough headroom so that you can boost everything up to your target level (LUFS).

[@adimology]

if you have to reduce the noise (preamp & mic noise), when do you do that step? first, before the compressor, after the compressor, or after loudness normalize? thanks

[@curtisjudd]

Before loudness normalization (which includes compression).

@@curtisjudd I just moved from the Zoom F4 to the SD MixPre 6II. Am I going overboard if I will record a three person 1-2 hour long podcasts all in 32 bit? And what about the sampling rate? I was also wondering, if you use the mix assist plug in is is just recorded to the L+R mix? Which means that you cannot tweak all the individual tracks in post with the mix assist plug in? Thanks.

[@curtisjudd]

@@OliGudbjartsson12 Hi Oli, I don't usually use 32-bit for recording spoken word audio, but you can if you want. SD cards are cheap so it isn't much of a problem. I'd use a 48kHz sample rate for spoken word recordings. MixAssist only affects the mix channels, but you can still record isolated channels for each of the mics so that you can do a more manual/in-depth mix in post if you want. The MixPre gives you total freedom that way. (so did the F4, for that matter).

[@tech.inspector]

When I reach a True-Peak of -1,5db with Loudness Control and look on the right side where the Y-Axis shows the dB I can see that my audio is nowhere over -3db. Why does the loudness control show me a True Peak of -1,5db instead??

[@curtisjudd]

True peak takes into account that when digital audio is converted back to analogue to play out via speakers or headphones, the waveform can actually go to a higher amplitude between samples.

[@kotolows]

Izotope RX Advanced costs way too much comparing to Resolve Studio. Could you show how to do loudness normalization with the latest Resolve Studio Fairlight only?

[@galachiev]

Huge thanks for your work, Curtis! This topic is very important for me. Now I’m trying to master my first short film. I already have an experience working with videos like one in this tutorial, but films looks like much more complicated. I’ve seen your review of your short film audio editing. There was many post processing applied on the tracks, but final loudness optimization hadn’t covered there. Can steps from this video be applied on the short too? (Mixing everything in the one track and making it louder with compression and gain) Or workflow with films is different? I listened to my audio tracks and it seems like most of them requires their specific noise reduction, EQ and compression. Also it’s hard for me to master them without separate volume changing for each clip. That’s why I’m a bit confused.

[@curtisjudd]

Hi Galach, generally, the workflow for narrative film is to edit and mix first. Clean and adjust each clip until it all sounds good. Then bounce the entire mix out to a stereo track and loudness normalize that like we showed here.

[@galachiev]

@@curtisjudd thanks for answer🙏 Also I’d like to ask once more thing you don’t mind. In your video about short film editing, you worked in Audition with project file from FCPX. Now you’re using Davinci, I’m using it too. Does it allow to link workflow with audition? For editing each individual clips and tracks and have an opportunity to make changes in both programs from time to time. Or it’s better to use Fairlight for this purpose. And the last question about separate clips editing in davinci. I used to apply all my effects while editing audio to have an opportunity to see changed waveform (for checking loudness, noice ration, etc) like you showed in this tutorial (I used audition before). But in fairlight i found only methods to add effects on the track, not to apply it. Also it hasn’t as nice wide waveform interface as audition Izotope do. (There even loudness on the mixer is strange, -10 is set to default for unknown reason) This makes my edit process kind a “blind”. But I don’t know. Maybe it’s the only way o should to work

[@curtisjudd]

@@galachiev DaVincia Resolve's Fairlight is a very different beast to Audition's waveform editor as you have discovered. I imagine there is a way to round trip between Resolve and Audition, but I haven't worked out how to do it. It is straightforward to set up round-trips to Izotope RX using the external editor option. I don't know if that is possible with Audition or not.

Hey Curtis, I've been studying your videos all week and been learning a ton. Thank you. For Loudness Normalization, would an easier way be to just put in the loudness normalization settings in the Adobe Premiere Pro export menu? I see you can also specify the true peak value (like at -1 dB), so nothing clips.

[@curtisjudd]

You can do that, but often if you're normalizing for web to -16 LUFS, you need to do some compression first so that the audio doesn't sound distorted. Sometimes if you apply a limiter, like the export functionality does, and the audio hits up hard against that limiter, it will still sound distorted. Best to use a compressor first to manage the waveform peaks and get it sounding smooth while leaving enough headroom to get the loudness target you need.

In a much older video you recommend to target normalize to 19 lufs in case of a mono dialogue track. Do you still hold to this recommendation? 2. In Davinci there are among others two normalization modes BS.1770-1 and BS.1770-4. Is there a big differerene and if so which one do you recommend for dialogue?

[@curtisjudd]

1) yes 2) use the latest

[@averysandack]

Great video Curtis! Though KZbin’s stats for nerds on this very video of yours shows that you normalized it to -14LKFS. So why break your own advice for this one? 🙃

[@curtisjudd]

When I read stats for nerds on this video, it says the content loudness is at -3.1 which equals -17.1 LUFS. (-14 - 3.1 = -17.1)

[@averysandack]

@@curtisjudd Oh how strange, my stats for nerds on my iPhone shows content loudness at 0db, which would suggest -14LUFS. I just checked again, same result! Maybe this could be a mobile KZbin app bug?

[@matt113pagoda3]

Thanks again for the tutorial! You mentioned Izotope Rx, which costs $400. Do you know any other cheaper software? Thanks!

[@curtisjudd]

DaVinci Resolve with it's Fairlight tab is free and quite good.

[@nrjonesy]

Great video as always, watched a couple of times. Would it be possible to cover how you could achieve this using Fairlight/Resolve alone? Whilst it might take more time to do, it would be useful to see the steps you'd go through? Also Resolve 17 now seems to have a capability in the Fairlight module to right click and "Analyze Audio Levels", this seems to fix some of the issues with playing through the entire track to get a reading? What are your thoughts on this feature?

[@curtisjudd]

Hi Neil, once I finish mixing a film I started a couple of months ago in v16, I’ll take a look at 17.

[@RoccoWocco]

Could you show this process for a more challenging situation: Live streams / live podcasts?

[@curtisjudd]

Still working on that. For live, most people still just use a compressor or limiter and push the levels up until it sounds loud enough or meets an RMS level. The trick is to put a loudness meter close to the end of the signal chain. I haven't found a good way to do that yet since I stream directly from an ATEM Mini.

[@RoccoWocco]

@@curtisjudd Kudos for the lightning fast response! I see how that makes it more difficult. Perhaps it's worth a shot to recreate the workflow in software as a showcase? Either way I'm curious what you'll come up with. Good luck!

[@skymakai]

Appreciate the video!

[@curtisjudd]

👍

[@TheOneThreeFour]

Is there a reason to use compression to get the extra headroom required to do the loudness correction rather than a limiter?

[@curtisjudd]

Yes, you can generally create that headroom in a way that sounds more natural and less processed.

[@DaveKnowlesFilmmaker]

Hi Curtis, Great video but could you please explain what happens if you normalise a clip or track using the built in normaliser in Resolve. I see it has various setting such as ITU-R BS. 1770-, ITU-R BS. 1770-4, ATSC A/85, EBU R128, OP-59, TR-B32, AGCOM 219/09/CSP and Netfilx. Would using these do the same thing as you are describing in your video. I have searched to try and find what all these setting in fact do but drawn a blank so hoping you can help.

[@curtisjudd]

Hi Dave, those are just different loudness targets with slightly different specifications such as momentary loudness in additional to integrated (total program) loudness in LUFS or LKFS. Yes, they would do the same thing, but you will probably need to do a bit of compression on most dialogue clips first so that the transients aren't too heavily limited. For videos going to web, I just choose ITU-R BS.1770-4 and set the target to -16 LUFS.

[@DaveKnowlesFilmmaker]

@@curtisjudd Thank you so much for getting back. Are these then going to a different job than choosing Sample Peak Program or Sample Peak Program with a Target Level in dBFS chosen by me and would it be best to use this normalising track by track before mixing especially throes with dialogue? Also if you were making a video for a client to be given to them on a file which one would you advise?

[@curtisjudd]

@@DaveKnowlesFilmmaker I would just mix with your ears and then focus on loudness normalization at the end once you have the mix sounding like you want and balanced. Then bounce out the mix and loudness normalize the mix. If the video is going to be online, I would choose ITU-R BS.1770-4 and set the target to -16 LKFS/LUFS.

[@DaveKnowlesFilmmaker]

@@curtisjudd Thanks for your advice.

[@dandanliu6500]

Thanks for another amazing video, Curtis! When you do your mix, do you first compress the vocals, then once everything is mixed, compress the whole mix again (as shown in this video) for loudness normalization? If so, when you first compress the vocals, how do you know how much compression is enough? I thought we only had to compress the vocals. Ahh, this compression thing is so complex...grateful for your teaching in demystifying it.

[@curtisjudd]

Generally I just compress at the end, after everything is mixed, to prepare for loudness normalization. But you can do it in stages if you prefer.

[@dandanliu6500]

@@curtisjudd Gotcha, thank you! One question I have remaining is that of where to place the loudness levels of dialogue, music, sfx in your mix. I'm confused because I learned dialogue should be bouncing in between -12 to -15 dB, but then I saw you normalized your dialogue to -0.1 dB. If that's the case, where should music and sfx generally be sitting at?

[@dandanliu6500]

@@curtisjudd Thank you!

[@Benditlikehim]

Really good explanation but there's something I don't understand. If you keep it at -16 LUFS (with -1.9 headroom) and youtube normalises to -14 isn't it going to clip once the audio is turned up? I understand the reasoning from the other video to conserve dialogue audio quality but I think this method could be a false friend. If you don't compress the audio enough and don't leave enough headroom you could inadvertently make youtube clip your audio once it turns it up. Maybe I'm missing something here. Either way this was a really good video!

[@curtisjudd]

Hi Bruno. KZbin does NOT change the loudness of your video unless it is LOUDER than -14 LUFS (i.e., your video would have to be -13, or -12, or even louder). If your video is louder than -14 LUFS, it reduces the loudness to -14 LUFS. So if you normalize to -16, KZbin will leave it at -16 LUFS. So no false friends here. Just normalize to -16 LUFS and you are totally safe.

[@Benditlikehim]

@@curtisjudd That makes so much sense!! Thanks for your reply. My background is more in music and since Spotify does normalise it's risky to go under because you don't know what they will do. Once again thank you for your response and the very informative video. I'm really enjoying your RX tutorials.

[@studiotwentyone]

Excellent video Curtis.. but I have a question and sorry if it’s a dumb one (I’m learning).. When mixing my audio do I have to focus on what db I mix at? I have music and dialogue/vocals. I have read that I should aim for -12db for vocals (which I have done) and mixed music too however my overall export is way too quiet.. When you adjust the LUFS then does that not make my vocal tracks exceed the recommended -12db??

[@curtisjudd]

I'm not sure where the -12dB FS recommendation comes from, unless you are producing video for TV? If you use LUFS and aim for a target loudness for TV, then you do NOT need to worry about a -12dB recommendation. Instead, you'll want to hit the loudness target (e.g., -23 LUFS for European broadcast TV) and the true peak level no higher than -1.5dB, then you should be fine. But first you need to decide on a target level and that has to do with where your video will be screened.

[@studiotwentyone]

@@curtisjudd Thank you Curtis for taking the time to respond, I really do appreciate it. That clears up my confusion..

[@mcvidre]

Very helpful video showng how to approach audio laudness normalization. Do you maybe know any plugins just for normalization? I'm sure iZotope RX is great, but it's quite pricey for my current needs.

[@curtisjudd]

Youlean Loudness Meter. Also, Adobe Audition has some good included loudness tools.

[@arthurrump]

I use TBProAudio's free dpMeter plugin in Audacity and it works pretty okay if you want to play around with some things for free

[@curtisjudd]

@@arthurrump Thanks Arthur, hadn't heard of that one.

[@EnteCinema]

It has to be -14 LUFS for KZbin videos na ?

[@curtisjudd]

No. It has to be no louder than -14 LUFS for KZbin and for spoken word, I’d stay closer to -16.

[@bobuk5722]

Hi folks, you need Isotope's RX10 Standard as a minimum to access the loudness controls. Currently $299.

[@curtisjudd]

👍 many DAWs are starting to include loudness metering tools which you can use instead.

[@valis1680]

Hello Curtis, Thanks so much for this great video. There is this very strange thing in davinci fairlight that happens when I try to follow your steps. I put a short music clip on a stereo track to normalize it (nothing else). After normalisation it has an integ. Lufs of -20 and true peak of -4.2 (this is also confirmed by iZotopeRX8). But when I look at Bus1 of fairlight the music will clip at one point. The gain level of Bus1 is higher as in track1, but the gain knob of Bus1 is not elevated, no sound effects or pan or eq is activated. Do you have any idea what could be the reason? I think if you dont nobody will :-). By the way when I change the track type to mono the problem is gone. But than of course the nice stereo effect is gone, too. The only way to stop clipping I found is to place a limiter in Bus1.

[@curtisjudd]

It sounds like maybe there is some processing happening on Bus 1. You might also contact BMD support to see what they say. Best wishes!

[@_stevek]

I don't have iZotope Rx and I am trying to do this just in davinci. Also you can just right click on the audio track and analyze the audio in davinci to get the true peak and lufs levels without listening to the whole track. So I am compressing the audio in davinci then bouncing the compressed audio to a new track. But when I check it and normalize it I am having the opposite effect. When I right click and select normalize audio then I use the UTI-R BS, 1770-1 mode my true peak goes in the opposite direction and I end up with even less headroom than I did before. What am i doing wrong?

[@curtisjudd]

Hi Steve, I haven't used Resolve in a while, but last I checked you could only right click and check the levels and normalize at the clip level, not the track level. When you tell Resolve to normalize to a target, it has to move the waveform samples up or down to hit that target LUFS level. It sounds like in your case it is moving things up. So you'll probably need to do some compression first.

[@imagissonent9183]

Hey Curtis, I just started editing in Davinci Resolve full time but I am still not sure how good Fairlight is. How would rate Fairlight against pro tools or adobe audition? Also, would you consider doing some kind of extensive Audio tutorial in Fairlight? I am beginning to shoot scripted work and the audio comes out well, but every now and then I record something that needs quite a bit of work to correct, and I am just wondering if Fairlight stands up in that regard, or should I go about editing my audio in Pro Tools or something along those lines. I've seen Fairlight tutorials online for other folks some of them are useful but I honestly trust you more since you really do this for a living. And I'm interested in editing sound for scripted and narrative work versus a talking head on youtube. Thanks and I love the channel.

[@curtisjudd]

Hi and thanks! I just used Resolve 16 on a scripted short project (6 and 1/2 minute piece) which had a decent amount of sound design elements in the mix. I used about 25 tracks and started to experience some crashes. But aside from the crashes, I quite like Fairlight. In fact, I have a Fairlight Fundamentals course at school.learnlightandsound.com. You can see a walkthrough of the mix before we finished it over at kzbin.info/www/bejne/f4OZYXlre6-Na9U

[@europeanambience]

So where is the tutorial on compression? :)

[@petrub27]

but why can't you render the loudness control at 1.5 true peak and 16 lkfs from the beginning? why do i need the compressor as well?

[@curtisjudd]

Chopping off transients with a limiter doesn’t sound great - it will often sound distorted. Compressing gently pulls the peaks down so it doesn’t sound distorted.

[@petrub27]

@@curtisjudd thanks. thou your method works, I am surprised why is advertised differently on the izotope page.

@@petrub27 Marketing doesn't always line up with reality or with what actually works best in the real world.

[@valis1680]

Hello Curtis, Thank you very much for your video. With respect to your example, have you tried in the past using the loudness control module of RX for normalisation without using compression? I was surprised that you first compressed the audio in order to get more headroom before using izotopeRX. Using iZotopeRX8 myself I found out that the loudness control module of RX takes care of that automatically when loudness normalizing. I am not a pro, but if I set eg. integrated lkfs to -16 and true peak to - 1.5 then RX will deliver this even though the loudness increase was higher then my available headroom. RX will make sure that the peaks of your waveform will not pass the true peak limit while increasing the integrated loudness lkfs to the desired value. It would be very interesting to hear whether it also works for you.

[@curtisjudd]

Hi Vali, yes, it certainly works, but it tends to limit too heavily and that can be heard if it is too heavy. That's why I compress first so I have more control over how the final audio sounds.

[@valis1680]

@@curtisjudd Thanks, that was very helpful. Since I do mainly dialogue with very few wafeform peaks that need attention I never noticed heavy compressed audio by RX but very good to know that compression can be necessary in other situations.

[@curtisjudd]

@@valis1680 It is often better to use compression with dialogue, too. Just depends on how dynamic the voice is that you've recorded.
