Noise reduction feature

Hi,
I am working with Soundtrack Pro 1.1 and was wondering about the noise reduction feature. Is it useful? I shot a feature film that contains a lot of unwanted background noise like moving cars, chain saws and so forth. Will this built-in feature be able to bring some of the audio up to spec?

It is good for removing consistent, perpetual background noise. This means room noise from an air conditioner, and other kinds of consistent ambience. It doesn't help much with things that happen in the background at certain times, but not throughout, such as cars and bird chirps.
For things like cars and incidental background noises that are not perpetual, carefull EQ, Compression and Adaptive Limiting and Noise Gating are your best option. And, of course using your sound levels on the offending tracks helps.
The best way to deal with them is with careful mic positioning in the first place. Shotgun mics help with this as well as the use of lav mics. The closer your mic is to the person, the louder they will be in relation to the other noise in the room (which includes the person's echo off the walls).

  • Missing noise reduction feature in iMac 2012, Do you all know if that feature was available in previous iMacs??

    I have been having some issues in my iMac 2012, with the noise reduction feature. I have a MBP retina display that in system preferences has the noise reduction feature. However, in the new iMac 2012, I don't see that feature. Plus, I have been having issues with facetime, people that I call are telling me that they hear feedback whenever I talk to them. Does any of you know if the new iMac is supposed to have the noise reduction feature?

    I was trying to find the "use ambient noise reduction" option in my new iMac, but in the new iMac I don't have that option. I was wondering if in previous iMacs versions had the "use ambient noise reduction" option available because I have an issue with facetime, people that I am calling are telling me that they hear feedback or static sound and they can't hear me well. I believe that with the "noise reduction" option, that problem will be solved. However, in my iMac, I don't have that option only in my MacBook pro. The reason that I am asking if in previous iMacs versions had that option is because I believe that there might be a bug that Apple needs to fix in order to have that option available in iMac.

  • Noise reduction in v.2.0.2 may be broken feature

    Since using this update, noise reduction feature does not seem to function. Setting a noise print and running noise reduction does not result in reduced noise. The timeline waveform does not redraw, and noise is still audible regardless of db setting. However, low db settings do introduce the familiar gurgle noises. Does anyone know if this can be fixed, is there a workaround, or do we need to wait for another dot release?

    I am having the same problem plus I get an "Uncaught Exception" error when I try to use it and then it crashes.

  • Cant get noise reduction to work

    when I apply the noise reduction feature to a grainly picture nothing happens.  am I missing a step?

    It's subtle. Maybe zoom in and look at it. The M key will let you toggle to the Master file so you can look at the before and after quickly.

  • Noise reduction on PS touch doesn't work

    Hi, I have just purchased the Photoshop Touch app for iPhone, mainly for the noise reduction feature but the noise reduction in it does not work.  I move the slider and nothing happens.
    I also have Photoshop Express, and the noise reduction works fine with it (it just asks for more money to Implement it).
    Please advise

    I've tried but the resolute is the same.
    This is the only feature that doesn't work and the main reason the I've bought this app.
    it's kind of  Disappointing.

  • Noise Reduction capabilities

    I am just recently getting on board with Lightroom and even have a copy on pre-order. I am attempting to digest as much info as possible while waiting for delivery. My question is this (and I apologize if the topic has been covered in detail), does LR have a Noise Reduction feature? Is it considered adequate or should I be looking at a Noise Ninja or equivalent to augment LR. I have recently switched to using RAW exclusively and I shoot high ISO due to my subject matter. Looks like LR will cover 90% of my post-processing needs, can't wait to start using it.....thanks for any insight into Noise removal...and almost forgot, if a third party Noise tool is recommended, does LR support a plug-in type approach or should I obtain a stand-alone version..... Many thanks.

    This thread could go on for ever.
    Although it is generally agreed that the noise slider almost may as well not be there and the sharpening is poor, let's remember this is a metadata editor and there are plenty of pixel editors including adobe PS and Elements + plugins that do these jobs. If it was a choice to wait another 6 months for these tools to be developed further or have ver 1 NOW - I'ld vote for NOW everytime.
    Comparing the scolls / decoration and NR/sharpening as alternative development tasks is spurious, the decorations could be a high school basic computing exercise, not so decent noise reduction.
    As this is a metadata editor we have to remember that what is saved is settings. If we use this product for noise reduction now, do we have any guarantee that with future versions with improved noise reduction, what we see on the screen now will be the same when opened in two years time with Ver 3.1. I'ld rather have LR as it is now, and let them take their time and get Detail functions right before I rely on LR to do these. I want to get on with organising my images with LR, I can live with exporting into a .tif for fine tuning in the meantime.
    I also want to be able to apply noise reduction selectively to areas of an image, but how much can we expect from a metadata editor?
    If I was as angry about features of a motorcar as some of the contributors here seem to be about LR, then it's easy, I'ld go and look for another make of car. I wonder how many other people like me bought RSP at the introductory price of $50USD and now for that $50 are in line for a free copy of ver 1.0 - sounds pretty good to me even if it did nothing except organise my images! The results I'm getting in develop I love (except noise) so I'm really pretty happy. If I had to pay full price for V1.0 AND wasn't happy then I'ld simply put my credit card away until version 2.0 is released.

  • Noise Reduction + Adjustment Brush = Smooth Skin

    A combination of the amazing new Noise Reduction feature in an Adjustment Brush would be the ideal solution for Skin Smoothing.

    I confess (due no doubt to my complete lack of appreciation for the Adobe development process), I thought they might slip lum-NR into the brush before releasing Lr3. Oh well - de-sharpening brush works pretty good too.
    The "de-sharpening" brush is de-sharpening from -1 to -50 and actually blurring from -51 to -100.  Combined with -clarity, I find it very effective on skin.

  • Noise reduction makes robotic voice

    I have been using Noise Reduction feature on "Audition" with no problems. When I have upgraded to "Adobe Soundbooth" I have an issue with this feature. When I turn it on I hear robotic echo of the voice no matter what the parameters are, even if the slider of parameters is on the 0 point (no noise reduction at all). Furthermore, it makes no difference if I am doing it with noise reduction profile or not.

    I tried using noise reduction for old recordings namely background hiss...then I discovered the audio effects work better for this...called "remove hiss" and also in the simple effects "Parametric" called "Under a blanket"

  • Where to put noise reduction into workflow (PSE5)

    If you notice noise in your photos, at what point in your post-processing editing do you use the noise reduction feature of PSE5.0. In the beginning after cropping? Or, later on after color correcting or lighting corrections? Or, somewhere in the middle?
    Thanks for thoughts.
    Peter F.

    Peter,
    I agree with Jim that the order may change but as a general practice if I need to adjust color I do it after any lighting (levels or shadows/highlight) changes since they usually change the color in my pictures. Most of the time I adjust saturation selectively particularly if sky and/or water are concerned. As a final step I apply various amounts of unsharp mask. From the 3 cameras I have owned (2 Olympus and the current Panasonic) I have never found a picture that couldn't be greatly improved either overall or selectively by LIGHT application of usm.
    Being basically lazy I always give Auto Smart Fix a shot as a first try and either go from there or undo it. :)

  • Best noise reduction?

    mac 10.5.8 - FCP studio best noise reduction technique and/or plug in?
    thanks!

    Assuming you're asking about audio noise and not video noise, SoundTrack Pro has a nice noise reduction feature.  You have to set a 'noise print' of just the offending noise, then apply that print to the rest of the track.

  • The noise reduction in Audition stopped working.

    For the past while the noise reduction feature in Audition stopped working. The adaptive one still works and its nearly as good but I OFTEN need to be able to sample the noise and filter it out and it simply does nothing now. You cant hear any difference when you play it and if you apply it anyway the file is unchanged. Need help urgently.
    Thanks!

    Thanks. The live chat guy after verifying me and all that stuff told me he was photoshop only and I had to call support. Is there a link where I can just download Audition and reinstall it or how can I do it? Any help appreciated a great deal.

  • Feature request: local noise reduction...

    I love the local corrections in LR2, and I'm using especially the local sharpening feature a lot. But I'm really missing a local noise correction feature (at least for luminance noise). It's such a shame to be able to do about any correction that I need inside Lightroom, but still having to make a round trip to an external noise editor to remove local noise. Especially since doing noise reduction as the last step doesn't seem to be very efficient at all.
    Local noise reduction would make this already great program so much better (at least, to me).

    >My understanding is that sharpening does not add noise, but emphasizes the noise that's already there, making it appear from being insignificant to noticeable.
    We're being overly semantic here of course, but it just depends on how you define it. If you define noise as for example the root-mean square deviation from the "real" image (a very common definition but it ignores the noise's spectral distribution), than absolutely sharpening a noisy image adds more noise. Sharpening operates as a high frequency amplifier, amplifying edges that are just noise instead of real edges, so it basically amplifies the noise that is there, leading to an increase in apparent noisiness. The same is true for clarity. Clarity is basically a sharpening operation at a very high radius. If your source image is noisy (especially if it has a lot of low-frequency noise - i.e. "grain"), it will also amplify it. Conversely, negative sharpening results in reducing high frequency noise. as it is just a small radius blur effectively.
    >Moreover, sharpening in LR develop is considered capture sharpening, where the small loss in sharpness form the RAW format is regained.
    The sharpening brush is different as it is meant to be a creative sharpener. It definitely amplifies noise if you push it. And even so, using Develop's capture sharpening, it is indeed possible to amplify (=add) the noise using the capture sharpening if you use the controls wrong. The capture sharpening has the superb mask generator that can be used to protect areas that are not edges, limiting its tendency to amplify noisiness. However, it will amplify noise near edges, sometimes making them appear as if you have a waterpainting. This is also an example of amplifying noise. Remember, even if these tools are meant to do a certain thing, it doesn't mean they cannot be made to do something else.
    >To just regain lost RAW sharpness at the expense of noise would seem almost like defeating its own purpose.
    Sharpness and noise go hand in hand. There are smarter and less smart algorithms but fundamentally, sharpening always amplifies noise, and noise reduction always reduces sharpness. As I said some algorithms are better and limit the effect, but the bottom line is that there really is no way around this.
    >Or, is it more correct to say that applying -ve clarity/sharpening will make the noise "Appear" less obvious, but not actually get rid of it.
    Appear less obvious is exactly the same as reducing it. Your eye is very good in judging noisyness as it is very good at recognizing patterns and so you can easily see what is noise and what isn't. If an image appears less noisy, it is less noisy. Computers are not that smart yet and if you call a tool clarity, it does not magically know how to not amplify noise or how to not reduce noise when using it negative. Same with sharpening.
    Conclusion: negative sharpness & negative clarity == noise reduction. They are just not as good as some dedicated noise reduction algorithms as they are not primarily coded to do noise reduction. They do have that effect however.

  • 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

    I use negative sharpness combined with negative clarity and/or contrast for blur effects. It's not unusual that I stack multiple brushes when -100 isn't enough 
    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.

  • How do PS CS3 Noise Reduction Filters compare with dedicated third-party plug-ins?

    Am I missing something by not installing a dedicated Noise Reduction application into my PS CS3? Can Neat Image, Noise Ninja, Noiseware Pro, etc. do something that the PS CS3 Noise Filters can't do? Do these third-party aplications do it better?
    Since I like flashless photography, and I generally carry with me small-sensor compacts when I travel, I'm frequently confronted with the problem of digital noise. I've always wondered how the third-party noise reduction applications perform in comparison with the Photoshop Noise Filters. I hope someone in this Forum has been able to acquire direct experience on this topic and will be kind enough to share this experience with us.
    Kindest Regards,
    Conrad

    Conrad,
    ACR 4.3 has better NR (noise reduction) than previous versions and can handle NR in most normal situations. However, available light photography with a small pixel sensor may require more NR and the specialized plugins such as Noise Ninja, NeatImage, and NoiseWare Pro can do a better job. I have all three and they do an excellent job, but I currently use NoiseWare most of the time.
    Here is a demonstration of NoiseWare vs ACR NR, using 100% crops of an image taken with the Nikon D200, 1/320 sec at f/2.8. The image is reasonably sharp at normal viewing conditions, but has quite a lot of luminance noise. It was rendered with ACR and the settings were exposure +0.85, brightness +60. One thing you learn early in this type of shooting is to expose to the right to reduce noise, but this may conflict with stopping action and reducing camera shake. More exposure would have helped this image, and one should try to avoid exposures requiring this amount of positive exposure adjustment.
    The results are shown below, followed by some discussion. Other comments are welcome. Color noise is not prominent in this image and I left color NR at its default.
    ACR, No sharpening, no NR
    ACR, Luminance NR 53, no sharpening
    ACR, No NR, No sharpening, NoiseWare default, no sharpening
    Noise reduction and sharpening are antagonistic processes. It is important that NR is applied before sharpening--you don't want to sharpen noise. Following NR there is an inevitable loss of detail, and some sharpening is necessary to restore the detail, but this also brings back the noise. One can use masks and blend if sliders in Photoshop in both NR and sharpening to mitigate some of these effects, and Bruce Fraser discusses the details in his excellent book on sharpening.
    If you use an add on such as NoiseWare, you should turn off luminance sharpening in ACR. In doing so, you lose all those nifty sharpening features that have recently been added to ACR. I leave color NR at the default. It has a minimal effect on detail.
    In adjusting the NR in ACR at 100% viewing, I estimated that a luminance setting of +53 was optimal. Beyond that, blotchy artifacts appear in the image.
    For NoiseWarePro, I used the default settings with no sharpening. The NR effect is dramatic, but detail is lost and some sharpening is needed. This could be applied in NoiseWare or in Photoshop, perhaps with a plugin such as PhotoKit Sharpener. Personally, I have found that PK does not work well with this type of image because it bring back noise and produces artifacts.
    In all of these examples, sharpening is needed following the NR. One could try to use surface masks to keep sharpening in Photoshop with the unsharp mask away from the edges. However, I find it is difficult to get a good surface mask, and I don't take the trouble.
    For now, I use the sharpening built into NoiseWare. I don't know how it works internally, but it does have a slider for detail protection, and you can play with this to get the best result. It would be best to have the robust NR of the add ons built into ACR much like NoiseNinja is built into Bibble Pro. However, this is an ACR forum and I would expect that ACR is the preferred raw converter of those who frequent this forum.
    After expending this much effort on the post, I hope to get some helpful feedback.

  • Are there any other enhancements in noise reduction tools in CS6

    Are there any other enhancements in the noise reduction tools besides the improvement mentioned of the spot healing brush. Are there improvements on the click and pop removal tool and the noise reduction in the spectral editing view. Quite anxious to know...

    Paul:
    Welcome to the Apple Discussions. There is a hidden feature for changing the Redeye and Retouch tool size:
    How to Change the Size of the Retouch and Red-Eye Removal Tool
    Type Caps lockControl9
    Undo caps lock
    Click on the Retouch or Red-Eye Removal tool
    The tab key will toggle between cursor types, a cross or a circle
    The "[" and "]" keys decrease or increase the size accordingly.
    NOTE: Using the "{" "}" keys will will change the value next to the circle and that represents the degree of change or intensity that the tool imparts on each pass.
    Also check out the tip at the end of my signature for backing up the library database file on a frequent basis.
    Do you Twango?
    TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
    I've written an Automator workflow application, iPhoto dB file backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.
