  • fixing audio

    shot a reception with my ex last weekend and the audio is hot, i had limiter set on and tha agc on. havent had it happen before. anyone up on any good audio programs that may help. i read the the noise reduction filter on sound forge could improve the audio, any input greatly welcomed

    Jim, it depends how bad the distortion is.

    Sound Forge and other some other audio programs have a Clipped Peak Restoration Plug-In. This plug-in can rebuild waveforms that have their peaks cut off, but there are limits to how successful this can be.

    From the Sony manual: "Clipped Peak Restoration should only be used for material in which clipping is minimal. Heavily distorted material with areas where almost all peaks are clipped is often unsalvageable."



    If you don't already have Sony Sound Forge, try a Google search for other audio programs that might have this function.

      Audition has some capabilities in this area. (Not sure if Adobe change it from what was in the earlier releases as part of their restructuring in recent releases.)

          Unless Audition has a suitable process for reducing distortion, noise reduction is not what Jim needs in this case.

            It depends how bad it is. Sound Forge or Audition would
            serve you well. I have the latest Audition, CS5.5, as well as
            1,2, and 3.

              Don't know what your budget is but take a look at RX2 from Izotope.
              Don't remember if there is a demo.

              I have used it on some client audio and it worked very nice.

              I did also send the audio to Samplitude for some sweeting. The restoration is a multiple step process.

                    Don't know what the issue is but I never had any problems with download from Izotope.
                    Have to warn you tho RX2 is not a point and click app.

                    It is a very very powerful audio Restoration app but you have to read the manual....

                        Jim,

                        Can you post a small section of the audio that has the distortion? About 10 seconds would be enough to test.

                        I would be willing to put it into Sound Forge for you to see if it is salvageable

                        If it is beyond repair, it could save you the trouble of learning a new piece of software.

                          Audition calls it "Clip Restoration." From the user manual: "Adobe Audition’s Clip Restoration filter can remove the evil occurrences of clipping from your waveform. It does this by actually “filling in” the clipped segments of the waveform."

                          The program offers sevaral parameters to tailor the correction process.

                          BTW all my ex live in Texas.:-)
                          It a shame to have them so close.
