Question

Scripting an incremental repeated DeHummer effect

I have a file that got some weird interference from something when recorded, so the wave editor shows a grid of thin horizontal lines every 50 Hz from the bottom all the way to the top. Each can be easily removed with a well-placed DeHummer, but doing that 400 times manually is not realistic, so I was thinking of creating a basic script (or Favorite, as I learned it's called) for the first DeHummer at 50 Hz , and then see if I can edit it's file (for example in a spreadsheet) to add all the other frequencies. The problem is I can't even find the file for the Favorite I created.

Does anyone know where these Favorite files are stored (on a Windows 10 system), or maybe a better way to do what I need?

I'm pretty sure that you can't extend the number of notches that the DeHummer will handle - it's inherently fixed in the design of it, and the same thing applies to the Notch Filter, which is the other filter you might consider. So your only possibility is to run whatever you use recursively in the favorite. I'm pretty sure that it will take longer to edit the Favorite file than you realise - the whole thing is stored in .xml and is very unlikely to be amenable to being interfered with by a spreadsheet! But hey, if you really have that much time available, the file is here: C:\Users\[username]\AppData\Roaming\Adobe\Audition\13.0\Favorites.xml

 

But, unless you have a lot of files to process, I suspect that it will be quicker to remove this interference manually, as far as you can. The higher in frequency it goes, the more chance there is that anything you do will interfere with the wanted signal in a less than desirable manner...

Thank you for the info, I expected the file to be in a more "script-like" form, not an xml (because I saw these favorites also being called "scripts" in some tutorials). Maybe I could find a way to make the xml work (just repeatedly applying the same DeHummer effect with every next one increasing the frequency by 50 Hz), but in the meantime I found another solution with an acceptable result: just "learning" the interference noise from a fairly long silent portion of the audio and removing it from the whole file; the audio being just a voice recording the "damage" was not too big. I tried the "Sound Remover" too, but it's too limited and much too slow even on my 16-core machine to be of any use.
