Sound Rescue: Cleaning Up Dialogue Audio in Adobe Audition
Вставка
- Опубліковано 12 вер 2024
- Have you ever finished a video shoot, downloaded your video and audio to your computer and found that your audio has some issues that make it less than optimal? Noise, almost inaudible levels, etc? Most of us have at some point. In this episode I'll show one case where I cleaned this up enough so that the audio was usable.
This episode shot with the following:
- Nikon D600
- Nikkor 50mm f/1.8 D Lens
- Tascam DR-100 mk II Field Recorder
- Audio Technica AT899 Lavaliere Microphone
- Smart Screen Capture
Music by Curtis Judd
Hi Curtis,
This is EXACTLY the kind of info I've been looking for. Very practical solutions to the kind of problems that happen all the time to non-experts like myself.
I would definitely like to see more.
Thanks for what you are teaching. Much appreciated.
I agree--I had not yet solved this problem with my screen recording app--it would only include either my mic or my system sound. I just figured out last night how to include both and the next video will include examples along the way. Thanks for the feedback!
After all those years... still a useful video!
Thanks Tommy.
Thank you for the informative video. I would have liked to hear how each of the settings affected the audio, rather than waiting until the end to hear the result. I know you have to watch the total time, but even four or five seconds at intermediate stages would help me understand the different adjustments.
We'll put it on the list--thanks for the feedback!
Will do--thanks for the feedback!
Great example, really turned out well I thought. I will have to try out some of these techniques in the future.
This will definitely boost my audio!! Ausome video!!!! Please more videos on audio audition!!
+Saudi Food With Eman Thanks, will do!
Sorry, but background music? And the presenter's voice is clipping throughout.
Yes, lessons learned. Thanks for the feedback!
Great work here. Guess I'll want to learn Audition so I can play with these things.
Thank you for these tutorials! they are great!
You're welcome and thanks for the feedback!
A noise gate filter would have helped out a lot too so you can block the rustling in the background
👍
I use RX for noise problems. It is magical! Don’t know if you have used or played with it too.
Yes, I use it all the time these days
Thank you so much! Your how-tos are very helpful! Is it possible to reduce talking in the background? Say for instance you are editing a clip where people are being interviewed (without a mic) during a loud party. I'm thinking all of this footage I was given is trash...
Thanks Heather. Reduction of speaking noise in the background is a tough one. If there is a lot of chatter (more of a wash of chatter vs. one conversation) and there is enough difference in loudness between the primary voice and the background, the noise reduction in this video works pretty well. I hope you the best on cleaning that up!
Great video! Could you talk more about the parametric equalizer in the future? Thanks!
great video, you are an awesome instructor
+David McCrea Thanks David.
Nice processing , your a genius, thanks
Thank you so much Curtis! I have been doing UA-cam for years and my audio was always a a weak point and I now have a really good idea to fix it. Are you still using the same strategy when you record? Peak at -12db, normalize to -10db and remove noise in post. Have you done an updated video on workflow? I saw the video you did about your brothers workflow. But just want to say many thanks for helping teach this so clearly, will literally translate into $$$ for me.
Thanks! Yes, definitely still aim for peaks at -10 to -12dB. Here's a post workflow episode you might appreciate: ua-cam.com/video/VcMOBrdbHgk/v-deo.html
Thanks for the help. Using this info for a school project. :D
Really useful - thanks!
I haven't done any traditional video broadcast work--my audio experience comes from the music world where maximizing/mastering to -0.1 db is the norm. I notice that most professionally produced web content is mastered pretty close to 0 db. My suspicion is that for traditional broadcast, they do compression/limiting/maximizing while broadcasting and thus ask their producers to keep peaks lower but that's just a guess.
Could you do a sample of the noise removal processing thing on the Rode smartLav? The only thing that's preventing me from getting that lav is the really noticable noise floor. If you could remove the hiss and clean up the audio, I would buy it in a heartbeat.
I'm surprised that you set the audio peaks so high. The courses that I have taken on sound and sound for video suggest much lower maximums. I've been told that NPR wants the peaks at -20 dB. Can you comment on the different recommendations?
Two questions:
1. First normalize then noise reduction or first noise reduction?
2. What about compressor?
Compress, then normalize, then noise reduction.
Excellent. Nice info.
+RallenMan thanks
Nice video, it'd be great if you could cover mastering/volume maximizing in more details. Thanks.
Great info. I've been applying the noise reduction first, but maybe I should normalize *before* applying noise reduction.
Thanks Jared, experiment with both. I've been doing NR first in some cases too. This workflow is in a constant state of refinement and adapting to different situations.
Light NR first, normalize then another light NR. I find two lighter NR runs sounds better than an extreme one.
In a separate video, where you go through compression settings, you normalize your track to -0.1db from "favourites." I noticed that once that is applied, the capture noise print function is greyed out (audition cc). I suppose I should clean the audio before applying compression.
Yes, before is best.
I've been using your tutorials to try and fix some audio that I need to use and can't reshoot. I wonder if you could help? Fuzz was recorded from the microphone throughout so there is a constant and very loud hum that I can't get off using the Noise Reduction tool. Any advice?
Hi Giorgia, I assume you are using Audition? There is a dehummer tool which is worth a try
If you are in the US or any place where the electrical grid operates at 60hz, I’d start with the “Remove 60 Hz and Harmonics” preset. Good luck!
you could try to add a de-ess filter soften up the s sounds
Good idea, thanks.
Thanks for the useful video
You're welcome!
thanks. it was very helpful.
+form less 👍
Thanks - very helpful. I am still struggling to improve my location audio with lav mics. Ideally, I want to fix the problems in camera but this intro to post is uesful.
Hi Chris, I just watched your Hamilton Hermitage Ruins video. Where is the mic placed in this case? It sounds like it is not very close to you.
Thanks curtis. Could you please tell me how to get rid of the noise that resulted from this process? Or is that necessary?
Yes, here's a tutorial where we show how to use the noise reduction effect in Adobe Audition: ua-cam.com/video/1lIjFBG6w58/v-deo.html
Curtis Judd Thanks for helping me. I know this tutorial has been out for a frw years, but I just saw it today. It was very good as you gave us a little more than here's how to reduce noise. I will watch this tutorial to learn some more. Thank you so much!
👍
Setting mp3 128kbit 44.1khz 16bit is on a recorder is big mistake. Wav is the way to go. 48khz is good enough but 96khz is preferable. , 24bit is minimum 32bit preferable. 16bit cd quality sounds good but for main recording use the best possible quality to have the most information while editing.
Generally, yes. Recording dialogue for video, we usually use 48kHz.
Can we edit the sound of already added vedios in youtube
You can add music, I believe, but cannot edit the sound.
You know, you could have at least told us what software you were using. I'm pretty sure you can still edit the title of your video so that those of us who don't have this software won't waste our time clicking on your video.
I just updated the title. Thanks for the feedback. I'm not sure what your intended tone was, but it came across as less kind than ideal (since we're sharing openly here). Nevertheless, I appreciate the feedback.
Of all videos to put background music on??? Hardly a very inspired move.
Hello Koyla Tolboy. I haven’t done that for about 5 years. Learned that lesson a LONG time ago. Thanks.
Curtis, rest assured your videos are first class! I don't know where I would be without them. I am a very keen follower of your channel. In fact I want to do one of your sound courses. Would suggest I start with 'Production Sound Fundamentals for Film and Video'. Many thanks and continued success with your channel @@curtisjudd
No, it was a fine comment. It was a very bad choice. Definitely a lesson learned.
Yes, Production Sound Fundamentals runs through how to make recordings for film and video. Definitely a good starting point.
I'm a voice over, that Will DEFINATELY AFFECT YOUR VOICE!!! It's a no no, and there you go, metalized voice
Hi Oihane, yes, it is best to avoid using noise reduction plugins, especially for voice over where you should be able to set up your recording space to avoid noise problems in the first place. And for video, I like to address noise issues while recording so I do not have to do it in post because it can definitely affect the quality of the audio. However, there are some cases for video, when you don't have a lot of control over the space, where using noise reduction carefully can improve the quality of the sound. Best wishes!
Yup. I currently have a fan noise leaking out my computer. I can't avoid it, and it's supposed to be at -60 to -55, still, it's loud enough to make have to remove it so when I normalize noone can hear it. I have issues with the noisgate, it takes some parts of my voice over, any suggestions?
I stay away from gates for dialogue. They're too obvious. I like Izotope's dialogue de-noise plugin (can be purchases as part of plugin bundle or included with RX).
we always use(d) little.gates even on studios, I think it's obvious for sounds you obviously cant remove xd I don't think I.can afford the plugin... hiw much is it?
Around $129 USD: www.izotope.com/en/products/repair-and-edit/rx-plug-in-pack.html
If you only could get rid of the rhymes.
