Better Dialogue Audio: Compression and Normalization

Having trouble getting your dialogue audio to sound really present in your film and video projects? In this episode we talk about using compression and normalization to sweeten up your sound and bring it to the forefront of your mix.
I show how to do this in Adobe Audition but you can do the same thing in most video editing apps like Premiere, or any audio editing app including Audacity, Reaper, etc.
Now I'm not claiming to be an expert on compression, so if you see things that we could improve here, please leave your input in the comments--we love learning to improve!

8 years later tip: When compressing dialogue, try setting attack to the smallest setting possible and set the release to 500ms. It will usually sound better and less compressed that way, while still accomplishing the end goal - making your audio louder.

[@SunriseWaterMedia]

Thanks 8 years later Curtis.

Noise reduction is typically done prior to the steps shown here. The reason for that is you do not want to increase and compress the noise. The point is to to get rid of as much of it as possible before those stages.Having said that once you do normalize or simply increase the gain you may now detect noises that you previously did not notice. In that case apply the proper filters that selectively target the specific noise types. Once you have done that and have the cleanest signal you can then it it is time to apply special effects and/or processing such as compression, loudness maximizing. limiters etc.. The biggest cause of problems starts at the recording stage. Make sure your levels are correct at that time AND what ever you do make sure you do not use the camera's built in mic.. Spend a few dollars and use an external mic and better yet connected to a separate recorder whose .track(s) you can sync up in post. Properly done that is your best insurance to capture quality sound with the least noise.

[@curtisjudd]

Good insights--thanks Bill.

[@JLitodiaz]

So are stating to do the Noise reduction Prior to Compression or after sir?
Thank You

[@curtisjudd]

Yes.

[@JLitodiaz]

Curtis Judd Before or After? lol
btw everything i have learned about lighting and aound so far has been through awesome videos!

[@curtisjudd]

Sorry, noise reduction first. :)

[@Akamo.]

This is by far the best video on this topic. Simply because it can be applied to any voice easily. Way better than the Dynamics Processing.

[@curtisjudd]

Thanks!

[@Rhythmattica]

I agree... But for simple productions.. But. To those that may be interested in a large production..
1st step : Dialogue editing
Dialogue Volume match, Possibly de-noising, ect.
Then its to Mixing..... Sometimes Room ambient matching, and real time processing is key here... , EQ-ing, Dynamics, ect...., .....Dynamic processing is the bookend. Especially in Film. Things cant be committed to a file...... Real time is a necessity..... . And when you have the tools, its just as quick.

[@lowkeyyoutube3673]

9 years later still better than most videos made today thanks man

[@TechUploaded]

This is a great channel! I really appreciate you taking the time to make these videos for those of us getting started with audio. This has been a huge help to my channel.

[@curtisjudd]

Thanks. :) In Creative Cloud, all of these plugins from Audacity are available in Premiere as well so if you don't need the visual feedback to you get in Audacity, you can speed up your workflow by just staying in Premiere.

[@curtisjudd]

Hi Alf, will do--I've played with them a little but need a little more time to really get them working well. I'll put that in the queue!

[@jox313]

Dude you are NUMBER ONE... Its the first time to me to understand what compression really is.. Thanks a lot

[@curtisjudd]

Thanks Basil.

[@MuchRockness]

Great tutorial! I've always been able to play with compressor knobs to achieve a flatter dynamic range, but now I understand the how and why. Thanks Curtis

I remember this was one of the only videos on CZcams, for improving audio. I keep coming back to this. Thank you, Curtis!

Thanks Editor!

[@mishalharbi777]

Thanks Curtis ! spent few hours watching videos on this topic and your tutorial is the only one that explains the process clearly step by step in few minutes.
the other related topic you covered and I found to be extremely helpful for improving dialogue voice is removing echo/reverb which can be present to varying degrees in room recordings. I highly recommend everyone to watch it too. keep it up and thanks again.

[@curtisjudd]

Thanks Mishal!

[@curtisjudd]

David Bialik I usually set my input levels so that peaks fall around -15 to -10 at the hottest. Digital is much less forgiving and I find that some digital recorders do capture distortion, even at -6db. Thanks!

[@curtisjudd]

@@abeeeshen3852 Hi Abeeeshan, I mean the gain or input setting when recording. While recording, I set the gain until the meters top out at around -15 to -10 or so.

Thank you very much for making this video.

I just started to dip my toe into the audio recording world with my recent purchase of a zoom h1. Your videos are fantastic. They get me to consider things I never even thought of before. I've been so focused on getting the right gear to get the image looking good and there is a whole slew of things I need to know to get the audio sounding equally well. I like to joke that youtube is my film school and if that's so, then you're one of my professors! Keep up the great work, Curtis.

[@PhontaineJudd]

Just wanted to send you a note telling you how grateful I am for your videos and sharing your knowledge. Your audio tutorial here has really helped my productions immensely. I am a professional video editor by trade (Dirty Jobs, American Chopper, Biggest Loser,, etc.), but I was never trained in audio. I would always go to the final mix, but had no idea what they were doing. So when I would try to make personal videos, they always looked good but had audio issues. Your tutorials have given me great insights as to how to better mix my own audio, and what a difference. Thanks!

[@curtisjudd]

Thanks Phontaine! And good job on your editing!

Thanks bacontrees! A few weeks ago I posted an updated episode that covers loudness normalization in detail since my workflow for editing dialogue has evolved some since: czcams.com/video/VcMOBrdbHgk/video.html

[@curtisjudd]

Sure. Which version are you using? Reason I ask is that the newest version (Creative Cloud) has all the exact same plugins as Audacity, including all of those I use in this video. Older versions are a little more limited.

[@ultimomos5918]

Thanks for the awesome video! I just recently graduated from a local audio engineering school and just wrapped sound mixing for my first local film. I'm used to editing all my audio in Protools but unfortunately won't have that entirely available for our post production process, so this guide is a very helpful look into Audition. Thanks again!

[@skaterboy1542]

Hey!!! Great video!! (As always) you should try adding a small room reverb (and also brimg down the wet sounds) to give it a little more life. I record music, so its a little diffrent but they are really close. But in the dialogue i have edited small room reverb helps... Great video! Again just something to try.

[@gabrielthemessenger]

You explain so well Curtis, thank you so much!

[@curtisjudd]

Thanks Gabriel!

[@tuber2kh]

I'm a videographer (depositions) and I've been using compression in the field for many years. Your video is a very good intro for other videographers to understand why we want to use it, and the settings you used are close to what I recommend for field compression. That was a good example that demonstrated the audible difference too. I'm glad I ran across your video.
Post processing is one way to add compression, but you can actually compress in the field too, and then you don't have to use post! I use small portable units like the FMR RNC (around $150). Some of your viewers might not have audio processing software, and field compression is another way to get it done. The biggest benefit to field compression is the the additional freedom that it gives the videographer. With the lows boosted by makeup gain, and the high volume parts attenuated, the audio naturally takes much more care of itself and leaves you to focus your attention on other aspects of the job. It's practically automatic audio.
Great video, thanks for posting it!

[@curtisjudd]

Thanks Kelly, I appreciate the feedback. Great point on the hardware compressor during recording!

Curtis Judd When in this process would you recommend doing noise reduction? At the very end?

[@curtisjudd]

Usually, the noise reduction I do is a high-pass filter at about 80Hz and cut off everything below that fairly aggressively (-36db per octave). I apply that right after normalizing the sound but before compression.
