Zoom in on Spectral Frequency Editor

Aug 28, 2012 11:47 PM

I am working on restoring a large number of old vinyl records, after applying Noise Reduction and Automatic Click Remover there still remains a number of clicks which have to be removes manually. The best way I find to do that is in the Spcctral Frequency Display Editor, to identify the straight red vertical line representing the click I have to click on the Zoom Tool Icon (at the bottom of the editor panel) 23 times to zoom in enough to see the red line.This is time consuming and tedious. Is there a better/quicker way to automate this step I. E. by way of a shortcut, if so, how do I create the shortcut

    I wish I  knew, as you say, it is an absolute pain!

     

    It is one of those features which seems worse in CS6 than it was in CS3 and earlier.  I expect we shall be told that it is yet another of those many consequences of the move to offering  Audition to MAC users, and that as such we shall have to put up with it for now.

    I haven't made the direct comparison myself, but I've heard elsewhere that people prefer the Audition 3 version of this too. But I don't think that this is a consequence of making it dual platform - it's just that the algorithm for healing has been altered. My guess is that the new one will work better with some glitches - but unfortunately the old one works better with more!

     

    As far as the OP's original problem is concerned, then I'm afraid that no, there isn't. Zooming in an locating them by eye is the only way to do it, otherwise the software algorithm would have presumably found them anyway...

     

    I don't know what the current status of investigating this is, as far as the developers are concerned, but I'm pretty sure it's been bought to their attention.

    To the OP. There are other easier ways of zooming in. Keyboard shortcuts for zooming by default the + (=) and - keys. Also if you have a scroll wheel on your mouse that can be used for zooming as well.

    SteveG,

     

    It is the zooming that irritated me - I never use the Automatic Click Reduction, preferrring to do this manually. 

     

    ryclark has provided me with the answer to that, for which I thank him very much!

     

    Now why could I not discover ryclark's solution for myself?  For my money the answer is the lack of a proper printed manual - I am too old and set in my ways for the new fangled Help, which takes you to a web page.  Search is fine, but the quality of the answers you get is too heavily dependent on the quality of the question that you pose.  Also the files tell you what the software can do, rather than how to do what you want.  I suppose I should invest in some training.

     

    I have printed out the pdf version, but it is neither paginated nor indexed.  There is not even a contents list, so you are reduced to turning pages and hoping to spot something useful.  Also it is setup for printing on American paper sizes; so with A4 the whole thing is littered with widows and orphans. Uggghhh!!!

     

    Rant over!

    While I don't have much good to say about the lack of printed manuals with complex software anymore, I can say we've received some excellent critiques of the Click Removal tool in CS6 and are investigating.  While the algorithm under-the-hood is the same as Au3, many parameters are not currently exposed that may help fine-tune the search and repair process.

     

    Also, in addition to the shortcut keys mentioned by ryclark, you can also right-click and drag in the navigation bar at the top of the editor - which might be too coarse for this particular need - as well as in the ruler above the waveform.  There are also shortcut keys which can zoom into a selection made around the offending click.

     

    Would some short, to-the-point training videos showing off the many ways to accomplish some of these basic editing tools be useful?  We usually post about new features or give unfocused examples, but I suspect there's a lot of value in some quick lessons on the basics.

    Thanks, Durin.

     

    I was OK on zooming the time ruler.  it was the cumbersome zoom of the frequency in spectral view that was bugging me.  all I could find was to R click in the scale and select zoom in, and again,and.........  Thanks to ryclark, now I just twiddle my mouse wheel.  Fantastic!

     

    My field is wildlife video, so I have no control over the weird and wonderful extra sounds that I acquire!  I make a lot of use of the Noise reduction, and click removal tool.  For use in Scotland, I need a low-flying F16 removal tool!!! 

     

    I have evolved a technique of highlighting the offending noise in spectral view and using this for a noise profile. I then click on Select Entire File and apply the effect.  I find this is far more effective than the blanket reduction achieved using the waveform - more of the audio that I want survives, and I get less of the "tinnies".  I have to zoom in on frequency a great deal to isolate some unwanted noise.

     

    I have never found the click removal effect very effective (sorry!), and used the Click Removal Tool enthusiastically from the start.  One disconcerting feature is that its diameter does not change when you zoom the timeline.  No problem once I got used to it, but I found it odd at first.  I also find that it is too "heavy" - it removes too much and it is easy to end up with silence rather than background.

     

    Silence is another one - why change from "Mute" in the R click menu?  I still have not got used to it, my autopilot expects to home in on Mute.

     

    Thanks again, for your response to my rant!

    The development team is aware of the lack of a "Zoom Way In" shortcut - one existed in Audition 3, but the feature had not been ported as of Audition CS6.  Don't be surprised if you see it in an upcoming release.

     

    As for Photoshop-like "Actions", Audition has a  similar feature called "Favorites" which you can use to record a series of actions and apply them again to other files manually or through a Batch Processing operation.

    BRONTESLC,

     

    I think we are at cross purposes a little, here. 

     

    My method of applying noise reduction will not work for short duration spikes as there is a minimum time needed for a noise sample.  I use it for narrow frequency band noise which may be continuous or short term, but always a second or more long.  You can, of course apply the noise reduction to just the affected part of the file by applying the effect with the affected section highlighted by drawing a marquee around it.  An example of the use of this technique would be the removal of the intermittent beep - beep warning of a reversing truck.

     

    Your point 6 - the opacity slider - would be a great addition to the spot healing brush.

     

    It exists in a different form in the Noise and hiss reduction effects already, but I find it difficult to use with any success in the hiss reduction effect.

     

    Durin,  thanks for the tip about favourites.  I had not appreciated that they offered so much power.  I shall investigate this as I often wish to apply the same effects to a range of clips.

    Bronteslsc. When you have identified the click by it's red spike in the Spectral view you can easily remove it without harming the rest of your music by one of two ways.

     

    1. Use the Spot Healing Brush to draw over the spike or

     

    2. Mark out the spike with the Marqee tool and then use Autoheal from the Favorites menu.

     

    As far as Zooming in is concerned the Scroll wheel is normally the quickest way. But of course the amount of zooming needed depends on how long your audio file is to start with. Long files can be a pain at the moment until we get some of the special zooming features back into Audition or some way to script the view and cursor into a Favorite.
