Clipping Peak Removal?

    Hi,

    I have several old tracks that have the odd clipped peak. I was wondering on recommendations for 'fixing' these. I realise that these are somewhat limited in scope, but in my case these are tracks that are fine except for 3-4 unsightly overs.

    I've seen adverts for various tools like Izotope and so on, but never used them (Happily using WL4 for close to a decade I guess.)

    Thoughts?

    First, do they actually sound bad? Sometimes they don't. Whip crack, something like that sounds fine if it clips. (All of those Xmas concert recording sleigh ride come to mind.)

    If you do want to fix 3 or 4 just do it with a pencil tool. Round off the clips by hand.

    No they really sound sizzly. Simply re-drawing the amplitude won't do it. (Acoustic guitar). I need an 'algorithm' that can reconstruct what the sound -shoulda- been. I know these exist in really high end products last time I looked (5 years ago?). I had hoped that the tech had dribbled down into the bargain basement---as these things tend to do.

    That's probably something the sonic manual declicking could take care of... Or the cedar Cambridge... Well, that's if there are not too much of those things...
    If you want, just send me the files and a note saying exactly where the problems are and i'll be glad to help you here...

    If it's got the crackles, then you'll probably have to use several different things. Izotope RX has some good tools, so does waves, Algorithmix. I'm sure there's others. sometimes you can get great results and other times not so great. Sometimes copy and paste works.

    Amen to that.

    Thanks for all the replies. I have been intrigued by some posts on other forums for using WL for this... I have v4, but my understanding is that there is a 'Spectral Editor' in 6 or 7 that is useful for this. I never upgraded because I never really understood what a 'spectral editor' is about. LOL (their docs are pretty 'terse' at best.) Anyone use that?

    In the meantime, I'll try the Izotope demo.

    Best,

    I use a spectral editor all the time to remove clinks and clicks from hitting music stands or a conductor's baton hitting the stand (or a performers steel plate in their head) or throwing the baton at a brass player in the back......but I digress.

    The spectral editor is one of my most valued cleanup tools. It is useful on the odd digital artifact too.

    John - The spectral editor you use is a standard plug in Samplitude/Sequoia?

    Actually, it's a built in feature to Audition. I've looked at some high end spectral editors but chose to buy some Royers and some True stuff and some............

    As you remember, I'm pretty low key out here in the other "backwoods" part of the country and I've not really needed the high end one with one concert exception. And then I still made do. I'm hoping that Reaper has something similar to this somewhere I haven't found, otherwise I'll never completely convert to it.

    (Different John, but I hope you don't mind)

    I use Samplitude's spectral editor pretty frequently. More than my other choices (including WaveLab & Izo RX), but mostly because I already have it open. Great piece of programming.

    Can you point me to some tutorials or give some 'how tos' on using such a thing? The sole reason I screwed myself and did NOT upgrade my copy of WL is that I could never get any insights on how to use it---the SB web site and forums are not exactly known for dispensing in-depth tutorials.

    TIA,

    Sure. There is a book published by Adobe that comes with audio lessons. Classroom-In-A-Book. I don't know if a library would have it or not. For other spectral editors, I don't know.

    Hi, ...
    The WaveLab 6 & 7 spectral editor is a (very) light version of Algorythmix ReNovator, which is a truly serious tool for clean extreme surgery on any audio.
    As a new feature of WL7 you get a few new Sonnox restoring plugins on top. I have not tried them myself yet, but they should be good. The PowerCore versions are...

    Thanks for the info. Sounds like I need to learn more about spectral editing. Somewhere. :D
