1. Re: Removing specific pops from phone recordings
ryclark Feb 5, 2012 9:11 AM (in response to JayNewWeb)Unfortunately there is no quick way to doing this sort of thing en-masse. The best tool for removing big clicks like these is to use the Repair Transient Favorite shortcut. Your eyes are by far the best detector of such audio glitches but you have to go through and manually remove each one.
However here is a little script that will speed up removing the clicks by automatically selecting a small portion of the audio to include the click and use the Repair Transient favorite shortcut. Select the text below and copy into Notepad (or similar text editor) and save as a .scp file into Program Files/Adobe/Audition 3.0/Scripts folder. Set up a new Keyboard shortcut (I use D for DeClick) and select the saved .scp script.

Open the Script menu from File menu and make sure that the Execute Relative to Cursor box is ticked.
Then all you have to do is Play through your file, Stop, Click on the click and press D. The click will disappear and leave the rest of the audio untouched.

JayNewWeb Feb 5, 2012 12:02 PM (in response to ryclark)Thanks! I appreciate it!
Before I even begin to attempt to implement this, can you please clarify the last sentence in your preceding post?
What exactly is involved in "Click on the click", please? How will this script be helping me select a small portion of the audio that includes the click?

3. Re: Removing specific pops from phone recordings
JayNewWeb Feb 5, 2012 2:02 PM (in response to JayNewWeb)I have to confess I'm really confused. At the top you say to use the Repair Transient Favorite, but I have no idea what that is, where to find it, or how to create it.
I also have no idea what you're referring to for creating a shortcut with the D key (I only see a way to associate a shortcut key with a menu item, not a script).
What I did do is to create the script file and try to run it, but that doesn't seem to do anything.
Please help me understand what you're trying to show me.
Thanks again.

4. Re: Removing specific pops from phone recordings
ryclark Feb 5, 2012 4:09 PM (in response to JayNewWeb)Repair Transient is, I think, one of the default options in the Favorites menu. My script uses that function to remove the click. When you run the script it automatically selects a range of a few samples where you have placed the cursor and applies the Repair Transient function to them.
At the bottom of the Favorites menu there is the option to Edit Favorites. When you click on that option a new page opens showing the items in the Favorites list above. There you can edit or make new favorite shorcuts. Click on New, give it a name like DePop and press a key in the Press a new Shortcut Key box. Then go to the Script tab and browse to where you saved the .scp file. Select the DeClick script and go to the top and Save. Your new Favorite will appear in the menu when you close the favorite Edit page against your chosen shortcut key.
See the Help file for further reading on Favorites.

5. Re: Removing specific pops from phone recordings
JayNewWeb Feb 5, 2012 4:41 PM (in response to ryclark)Oh, okay. I got it now. Thanks!
(Note that in Audition 3.0 I don't see anything called "Repair Transient". Maybe you have a different version of Audition. The general Help description under Click/Pop Eliminator just says it removes various transients.)
I've created the shortcut key to run your script. I see what it does, now -- as you said, it selects a short span of time following the cursor position and applies whatever it is that it does. I presume it's calling the Click/Pop Eliminator tool and applying the parameters in the script.
It seems to do a pretty good job. Once I manually position the cursor before a pop, I can hit the shortcut key and it will eliminate it while only partly reducing the sound that I do want to keep. Not bad at all. Probably not as perfect of a result as manually slicing out the pop surgically, but I doubt it will be noticeable at all in most if not all cases since this is just speech recorded over the phone anyway.
Man, I sure do wish there was a way to fully automate this. It's still going to require my manually selecting and removing hundreds of pops in longer recordings. That's an enormous cost in time spent!
Are we really, really sure there's no way to manually define a profile or sample that matches the characteristics of these pops and let it run automated? The Noise Reduction feature can capture a sample from a selection and run with that, but my pops are not long enough in duration for it to capture. I would like to think there's some way to approach this that will let it run nice and cleanly and fully automated by defining the pop characteristics in one of the tools. The reason I'm suspicious there may be a way is the totally consistent characteristics of these pops (not that I know much at all about what would be involved or how realistic is really is or is not).
Any other ideas?
Anyone else have any other ideas?
Thanks again!

6. Re: Removing specific pops from phone recordings
ryclark Feb 6, 2012 10:12 AM (in response to JayNewWeb)Audition's scripting functions are very limited in what they can do unfortunately. And it also doesn't provide any suitable tools for automatically finding these pops. T here are tools for Automatic Beat detection but Ican't find a way to make it distinguish these pops from the rest of the audio.
You might find it easier to find and quickly select the pops using the Spectral display rather than the normal Waveform view.

JayNewWeb Feb 6, 2012 11:56 AM (in response to ryclark)I really appreciate it.
Sprectral view isn't workable for me for these pops. I'll have to work in Waveform view.
Thanks again.
