Applying Noise Reduction to Subclips?

I have a long interview that I've cut up into subclips. It has the sound of an AC unit throughout that I'd like to remove in Audition and then save so that it is applied to all of the subclips. What would be the easiest and best way to do this?

I'm sure you've found some way of doing this relatively fast. But what I would do is use the Notch feature in the Filter & EQ section of the FX section of the Audio Track Mixer. You have to use your ear, but it can be very effective against a narrow range of bad frequencies. I.E. I've dialed in 120hz and set the Q really low and it practically eliminated a bad hum I had. It was awesome!
I just learned that you can make subclips, didn't know it existed, and I could have used it on my last project. HOWEVER, I would love to be able to apply an effect (like your audio effect) to the Master Clip and have it automatically apply to all the other subclips from that Master.
I'm going to make a feature request right now! Cause this would be awesome!

Vocal Irregularity after applying Noise Reduction

In this new project I followed Bob Howes instruction:
‘Set the FFT size (on the advanced menu) to 2048 and grab a noise print from a gap of "silence". Select the entire filed and do reduction by 7 or 8 dB and 15%ish reduction. Set the FFT size to the next one up, get a new noise print and do another pass with the same low settings. Keep going, upping the FFT size each time.’
This new project I started out first with a Hard Limit. Then I followed Bob's advise with managing by steps the FFT size.
Sample One is a piece of the original.
Sample Two is the results of the effects.
It sounds as though the speed of the vocals did changed - though one can listen to the vocal their conversation sounds - unnatural.
After removing noise is there another approach to redeem the vocals of those speaking?
Thanks!

Yes, you have very much overdone the Noise Reduction!
First, I'm not sure why you would need to first apply a "Hard Limit".
Second, are you sure you followed Bob's advice exactly, i.e taking a new noise sample and changing the FFT size on each pass? Are you sure you set everything exactly correct on that first pass?

Is there a way to apply noise reduction based on ISO value?

I shoot a lot of sports using auto ISO which means I get hundreds of images from a day with a variety of different ISO values, including all sorts of intermediate values (like ISO 280, for example). There are times when I'd like to apply LR noise reduction across the whole batch of images, but I'd like to apply it based on the ISO value of the image. For example at ISO 1250 and above, I want a particular NR Luminance value. From 640 to 1250, I want a different value. From 400-640, a different value. I know you can define some things at import time based on ISO, but that doesn't seem practical when the ISO value can be nearly anything as it would take hundreds of import profiles.
So, any ideas how to apply NR based on the ISO across a batch of images?

How do "defaults" interact with a preset applied upon import? I shoot RAW and apply a preset upon import for every import I do. If I apply a preset upon import will it override the "default" anyway? If that's the case, then defaults are of no use to me.
Yes - Lightroom presets are absolute, but unlike the default settings, presets don't have to specify all the settings. If a preset setting is specified, it will blindly overwrite the previous setting, if not specified then the previous value will remain unaltered.
DevAdjust supports relative presets: final-value = present-value +/- relative-preset-value

LR3: lack of processing feedback after applying noise reduction

Now with the bigger RAW files (7D's 18Mpix) Lightroom is becoming really slow.
On several ocassions after applying some noise reduction, and waiting for some 20-30sec for a visible result, I moved the slider back and forth in the wrong assumption that nothing happens, but in fact I was disrupting an ongoing operation. The problem in LR3 is that it does not show any of its tooltips with an information that a noise reducing operation is in progress.
I hope that the team would improve this in the next version 3.01, we need at least the tooltip to appear.
Thomas

i absolutely agree!
Now, in LR3 you can move the sliders very smoothly - but nothing happens for seconds.
Same happens with the local adjustment brush. You click on the picture and start to paint but nothing happens. After a few seconds the pin appears and MAYBE the first click for the mask is set. After that you can paint further.
Another thing is, that it takes longer for a RAW to be loaded. Sometimes i see the "Loading"-Hint for 10 Seconds or more. If i need to scan fast thru hundreds of pictures to clone away some things or make a face a little bit brighter, these loading times feels like ages.
Both is very annoying and was better in LR2.
BTW: I think LR3 has a serious memory leak because i can see LR3 slowing down over time. After developing about 20 pictures everything slows down, sometimes to a point where i think LR3 has frozen (no CPU usages, just standing still for 30 seconds or more). When i quit and restart LR3, everything is quick until the next slow down.
(older iMac 24", white model, 3GB RAM that can be used) - you may see this at a later point if you have 8GB or more RAM of course.

Noise reduction works in preview but doesn't apply to file

I have a file that I would like to apply noise reduction to. So in the tasks menu I click Clean Up Audio, then under Noise I click Noise... From there I can play with the Noise settings and get it to clean up nicely. But when I hit OK, it doesn't apply the noise reduction. It seems to be doing something to the audio because the waveform changes.. just not reducing the noise as previewed. Anybody know why it wouldn't be applying the effect? Other audio editing options seem to work just fine.

It is a 16 bit 44.1 kHz mono sound effect.. it is noisy and sounds like it could have been 8 bit at some point in its life cycle.

Noise reduction applied to high ISO .tif files in ACR 4.1?

Evidently ACR 4.1 applies noise reduction to high ISO raw files from Canon cameras, even when noise reduction is turned "off" in the plug-in (and this results in smeared detail). I have a 5D that I bought specifically for its lack of noise in high ISO files, and I don't want a software program forcing me into using noise reduction and ruining all those marvelous details in my high ISO raw files. Can someone tell me if there is a similar problem with ACR 4.1 if you open a .tif file with it? If not, I'm thinking I'm going to use Canon DPP 3.02 to convert my raw files to .tif, and then use ACR 4.1 to quickly adjust exposure, black point, etc., all of which is awkward and slow in DPP 3.02.
Rob

No, although ACR v4.1 does apply some baseline noise reduction to many raw files, I do not think that it applies any default NR to TIF files. Lightroom v1.1 does not apply any noise-reduction to TIF or JPG files by default, at least as far as I've noticed, so I believe this will likely carry over to ACR v4.1 as well. Of course you *can* turn the NR sliders up from zero and then it will! In any case, you'd be advised to test that theory yourself just to make sure, before designing a workflow around that assumption...

Adaptive noise reduction filter only applying to parts of a clip

MAC 10.9.4
3.5 Ghz 6-core
16GB ram
AUDITION CC
PREMIERE CC 2014
This is happening over and over to me, along multiple projects and multiple clips.
I apply Adaptive Noise Reduction, and tweak the properties. It sounds great but then when I 'apply', the filter is only applied to about 50% of the clip.....meaning it sounds great when tweaking the filter, but after when it is actually applied, only parts of it will apply.
IE, If I have a 15 second and apply noise reduction.......It sill sounds while tweaking parameters. Then after I hit apply, seconds 1 - 4 will sounds great (filter applied) seconds 5-9 will sound awful like no filter has been applied, and seconds 9-11 will sounds great again, and 12-15 will sounds awful again.
There is def something wrong here., This never used to happen in CS6, ever. Only when switching to CC.

Hi,
I have little use for/of the adaptive version of the noise reduction filters only because I want it ALL cleaner, so here is what I suggest: I left a very-detailed posting about "batch processing" in which I outlined using the the process version in the Waveform Editor. Give that post a read Re: How Do You Apply Process Effects To Multiple Clips In A Multi-Track?
Let me know if you need more help.

LR4 Feature request: Add local noise reduction

Hello,
I wish to apply noise reduction localy. On the backgroud apply a lot of and in forgroud (where the object/personn ist) a little.
See this example.
The current local noise reduction ist NOT the same as the one in the detail panel. It is a lof f less efficient.
Thanks

Thanks for the tip. My problem with blurring in Lr is that the blurred region ends up "too clean" (the rest of the photo has at least a bit of noise in it). I have dealt with it in the past by applying grain to the blurred region using an external editor - but that takes a lot of the fun out of doing the blur in Lightroom.

Noise reduction did nothing - no instructions for the process

I entered noise reducer in the help menu and "what's new in imovie comes up" - I am looking for info on the process to apply noise reduction and nothing applied even two layers down in what came up in "what's new in imovie".
I have bought the book iMovie HD 6 & iDVD 6 and it does not give direction on how to apply. It does say page on 157, "this effect minimizes white noise, crowd noise, and hum - but nothing else - no directions on how to apply!
My audio clip is selected in the time line and if it is as simple as selecting the apply button in audiofx, then select noise reduction, then select apply - IT DID NOTHING.
Is this how it works for application and out come?
Can anyone help,
jim

No, but the Help menu in iMovie does:
To add an audio effect:
Click the Timeline Viewer button (shown above).
Select the audio clip or clips you want to add an effect to.
Tip: To learn how to select multiple clips, see "Selecting clips" below.
Click the Editing button, and then click Audio FX at the top of the Editing pane.
Select the audio effect you want from the effects list.
Adjust the settings for the effect.
Different controls appear depending on the effect you select. For example, if you select Reverb, you can adjust the intensity of the reverberation by choosing a reverb style and dragging the Less/More slider.
Click Preview to hear the effect.
To stop previewing the effect, click Preview again.
If necessary, repeat any of the above steps until you have the effect the way you want it.
To add the effect to your selected clips, click Apply.
When you add an audio effect to a video clip, iMovie automatically extracts the audio from the clip. The extracted audio with the applied effect appears as a separate clip in one of the audio tracks in the timeline viewer. If you want to add multiple audio effects to the same portion of video, be sure to select the extracted audio clip to add the additional effects to.

RAW conversion bug with Noise Reduction

Hello,
I have found a serious bug in the RAW conversion when noise reduction is applied. When converting from two types of Canon RAW files (a CRW from a Powershot G6 and a CR2 from a 20d) I found that if you apply Noise Reduction to a RAW file on very low settings (the default setting in the NR function will produce this reliably) single-pixel lines appear at regular intervals throughout the image. Here is an example:
You can see several lines in this image:

A 100% detail of which is here:

Has anyone else had this problem? Can someone from the Aperture dev team fix this?
-Steve G

Well I find this filter is quite good in 'masking' block artifact that codec like xvid, or other low compression codec have. I only apply it if I find the block artifact is too much and I find this filter is less offending to my eyes than the block artifact.
In manual it said that if you have noisy video and want to lower the size then you can use this filter. It also blur the video a bit. But I suspect it is more than blur as I try gaussian blur in time line and the result is not as good. You can see the result as well. There is the tab between source and target and you can compare the result by togling between source and target tab.
BTW, anyone with 1 core, dual, or quad core, can you tried to encode with it? Just cancel it after few minutes as I want to see what is your processor utilization with this filter on. Also you can see how long does it take to process this video from the 'estimation time left'.

Any chance Photoshop itself will get Camera Raw's noise reduction and sharpening?

I would love to have the noise reduction and sharpening from ACR 6 in Photoshop itself for JPEG, TIFF, and PSD files. Yes, I know I can open those files in ACR, apply noise reduction and sharpening, and then have it then open the files to Photoshop. But it would be so nice if we could do that without having to go through Camera Raw.

Matt Howell wrote:
Yes, I am absolutely saying that the noise reduction and sharpening of ACR 6 is vastly superior to any filters in Photoshop CS5.
For those who only work only with RAW files this is a non-issue, but I sometimes prefer to use TIFF files generated by CANON DPP software or occasionally even JPEG's straight out of Canon DSLR's. Going through ACR just for noise reduction causes unnecessary color space conversions, as well as just a needlessly complex workflow.
Perhaps you should ask Canon to make DPP noise reduction better. I also do not think is a good idea to get too aggressive with noise reduction and sharpening when you first bring a image into Photoshop unless you only use the image single use for a particular output device. Your better off working with a somewhat soft image till you ready for output and then sharpen for the output devive being used. If you use strong sharpening and NR up front sharpeing again for your output device may produce unwanted sharpening and NR artifacts... There are several third party noise reduction and sharpening plug-ins that are better then Adobe Photoshop built in ones. Noise reduction has to be balanced too much will loose detail masking detail is important. ACR noise reduction provides masking adjustments and works well. Third party plug-ins offer offer advanced masking features also. Photoshop noise reduction filter has a basic preserve detail slider which I presumes does some kind of masking but this is not as good at ACR masking and third paty masking. You can of course add you own masking before using photoshop noise reduction filter. Sharpening also needs masking for sarpening will sharpen noise as well as detail.
IMO your better off with third party plug-ins that are designed to be the best. They keep getting better there is no clear winner for all images. I'm been satisfied with NeatImage and I have only had to pay for two upgrades. I had to pay for the addition the 32 bit plugin then and for the addition a 64 bit plugin. All other updates to NeatImage has been free of charge even the lates version 7 of the 64 bit plugin was no charge for me.

Adjustment brush with exposure setting cancels noise reduction

Hello,
I just noticed the following problem:
1) Camera Raw 6.5; Bridge CS5 (4.0.5.11); Mac OS X 10.6.8; Mac Pro 3,1; Dual Quad-Core Xeon; 8GB RAM.
2) Start with a noisy raw file (mine is from a Canon 5D II).
3) Apply Noise Reduction (Luminance:30; Lum Detail:75; Lum Contrast:0; Color:25; Color Detail:50).
4) Go to Adjustment Brush and set a non-zero Exposure value.
5) Apply brush to image and notice the Noise Reduction effects disappear (noise returns).
6) Click Clear All button to clear Adjustment Brush and Noise Reduction works again.
This seems to only happen with Adjustment Brushes with a non-zero Exposure value (applying brightness or other settings don't seem to produce the problem).
Anyone else seeing this?
Thanks!

Richard (and others),
Yes, very good idea to check that. The problem does indeed get applied to the full sized, opened image as well as to the display previews. After working with this more, I now notice that I was wrong to say that the entire noise reduction is cancelled - rather it "changes", sometimes subtly, sometimes more dramatically depending on what the noise reduction settings are set to. Further, how dramatic the "changes" appear depend greatly on the preview zoom (the changes are more subtle at 100%, but it can look like the noise reduction is completely turned off at 50% and 66%).
Now I realize that the noise reduction does not ordinarily display at all preview sizes (especially smaller ones), but this is different. At preview sizes where it does normally get applied, applying an adjustment brush with any non-zero exposure value (even just +0.05) can have the appearance that the NR is completely turned off for the whole image. Simply nudging the exposure value back to zero brings all the noise reduction back.
Also, to be clearer and avoid confusion for others, the change in noise I'm seeing is not localized to just the brushed spot. Obviously if one increases exposure, you'd expect to potentially see more noise. Instead, what I'm seeing happens to the entire image, even if I simply paint a single small brush dot, say in a far corner. Having the image change globally in response to painting a small spot with the adjustment brush cannot be a correct result. Further, this does not happen with any of the other adjustment brush settings like brightness, contrast or saturation. There must be something unique about the exposure setting that perhaps introduces a new step into the processing pipeline, and this step is affecting the entire image.
In any case, the problem only seems to be an issue in somewhat extreme cases and is less noticeable at 100% (and the finally opened image). It's more just annoying when previews are generated for viewing in Bridge, for example.
I suppose one alternative might be to rob a bank and go buy one of those new 1D X's. Then maybe I wouldn't have to worry about noise anymore.
Thanks for the responses!

Lightroom, Photoshop, RAW Presharpening, Noise Reduction Workflow Help

I'm tying to determine a best practices route using Adobe Lightroom, Adobe Photoshop and Nik Software Sharpener and Dfine (Noise Management Software).
I shoot only RAW with a Canon EOS 30D with good quality lenses.
I import the RAW files from the CF card directly (DNG and save) into LR, add keywords, organize, etc.
However, I am now at the point where I need to determine a sensible workflow that includes these steps:
Import RAW into LR as DNG.
Edit, as needed, in PS.
Apply RAW Presharpening (as provided in Nik Sharpener).
Manage Noise (with Nik Dfine (2.0 available in next 24 hours).
Apply usage-based sharpening prior to printing or saving final file version.
Maintain organization in LR.
My original plan was:
1. Import RAW in LR.
2. Open in PS.
3. Apply noise reduction.
4. Apply RAW presharpening.
5. Save (with new version being an "Edit" copy back in LR.
6. Maintain organization in LR.
I'm wondering, though, if I wouldn't be better off doing the basics to the files prior to LR import. Note that the Nik tools work in 16-bit mode.
This is theoretically what I'm thinking, and would appreciate other user's input:
1. Save RAW files to location on Mac.
2. Apply Noise reduction to RAW files with Nik software within PS (perhaps automated, perhaps batched).
3. Apply RAW presharpening to RAW files with Nik software within PS (perhaps automated, perhaps batched).
4. Import noise- and presharpening-adjusted files into LR, with metadata additions, etc.
5. Open files in PS as needed, with files becoming edit versions within LR.
Any thoughts?

To summarize, then:
First time opening a RAW file from Lightroom, LR automatically creates a copy and appends "-Edit" to the filename. If it's a RAW file, only available option is the third option in the dialog box: "Edit a Copy with Lightroom Adjustments."
Once opened in Photoshop, any number of adjustments can be made and saved. All adjustments are reflected in the -Edit copy when previewed in back in LR.
If, later, I want to perform further PS edits on the -Edit version, I have 3 options as presented in the dialog box.
1. "Edit Original (LR adjustments will not be visible)"
2. "Edit a Copy (LR adjustments will not be visible)"
3. "Edit a Copy with Lightroom Adjustments"
Option 1 will open -Edit version #1 (but it will not show any changes made in LR to the -Edit file when opened in PS)
Option 2 will create a copy of -Edit version #1 and open that new file, -Edit-2 (but it will not contain any changes made in LR to the -Edit file)
Option 3 will create a copy of -Edit version #1 and open that new file, -Edit-2 and it will contain any changes made in LR to the -Edit file
So, a typical workflow would be:
1. Import RAW file in LR.
2. Make adjustments in LR.
3. If needed, open a copy (by default) in PS via LR (command-E).
4. Adjust in PS, save.
5. Adjusted file is stacked with original RAW file in LR.
6A. Assuming no additional edits in LR, further PS adjustments can be made to -Edit version original, keeping just 1 stacked version in LR.
6B. If additional adjustments are made to the saved -Edit version in LR, and further PS adjustments are needed, I must edit a copy of the -Edit file, ultimately resulting in a second stacked file.

Lightroom 3.6 DNG and Noise Reduction Problem

Hello,
I did a search and couldn't find this issue listed. I convert my Nikon D90 raw files to DNG. Never seem to have a problem with that except that the display(s) seldom shows the results of applying Noise Reduction (Color or Luminance). If my display is at Fit or Fill I don't see the results of what I am doing. If I zoom in to 1:1 or more, then I can see the results. All works fine if I am using a jpg file, it is just the DNG files that do this. If I want to see the entire picture with Noise Reduction applied I have to switch to the Library Module. Then when I go back to the Develop module the main display goes back to not showing the Noise Reduction, but the secondary display is ok until I apply another effect then boom, back to Noise Reduction not displaying. All of the other changes I make work just fine. It is just the Noise Reduction that causes the problem. This is really a killer when I am working on photos. This problem existsed before 3.6. Does anyone else have this problem? FYI - When I switch to the Library Module it takes a few seconds before the secondary display shows the photo with the Noise Reduction applied.
I have a quad core 2.4ghz with 8gig of ram and Windows 7 Pro 64bit OS. Plenty of CPU and memory available.
Thanks,
Harold

LR is designed this way to improve speed. I think it varies, somewhat, with how high the ISO is where higher ISOs show NR more.
I find this annoying, too, and which there was a setting to allow LR to compute the NR at lower resolutions if one chooses, instead of Adobe choosing things for us.

Noise Reduction Programs as External Editor

Can anyone tell me if I can set up a noise reduction program (Noiseware, Noise Ninja, Neat Image, etc) as an external editor to LR and use the "round trip" feature used with PS/PSE? I don't currently have either PS or PSE, since LR has been able to handle my editing needs with the exception of noise reduction. Hence my research into free-standing programs.
Thanks in advance.
Adam

From the Noise Ninja web site:
http://www.picturecode.com/wiki/index.php/Main_Page
"It is usually best to apply noise reduction as early as is practical in the workflow. Post-processing adjustments like sharpening, contrast stretching, and color balancing can alter pixel values and noise levels in unpredictable ways. Depending on the amount of adjustment, this can make it more difficult for Noise Ninja to estimate noise levels. Sharpening, for instance, is a nonlinear operation that can significantly distort the distribution of noise values.
If your workflow requires that you use Noise Ninja after some other operations, then try to create noise profiles using calibration images that have been put through the same operations.
Running Noise Ninja early in the workflow is a good rule of thumb, but Noise Ninja can be applied at any time. Sometimes it may not be possible or practical to run Noise Ninja at an earlier point in the workflow. For example, most users are not using a RAW processor with plug-in that allows Noise Ninja to be run before other adjustments in the RAW processor."
