  • Over driven audio

    I just got back from a wedding and the audio came out a little hot. Its a bit distorted during the reception. What filter might make this a little better?

        I've had good results with Izotope RX when dealing with clipped audio.

          Adobe Audition (previously known as Cool Edit Pro) includes the capability.

              From what I've heard from users, Izotope RX is the king when it comes to clipped audio.

              You might also try a free VST plugin called "relife" available from:

              www.terrywest.nl

              I've not tried compatibility in Edius, but using Sound Forge as a host, I've been able to do restoration on modestly overloaded audio. Try using that with the clipped peak restoration tools in SF or Audition.

                From my experience compared to Audition I get a result quicker with RX.
                RX is a bit pricey but it does work very well.

                    I am playing around with the free izotope that came with Edius 5.X. Is the filter called declipper?

                      Audition (and I'm guessing the others mentioned work in the same way) can help with clipped audio, if the clipping is in the digital domain - i.e. the actual A/D converter was overdriven.
                      If however it was the mic pamp that was overdriven, so that the clipping occurred in the analogue mode before digitisation, then I'm afraid you are unlikely to get much improvement with the clipping restoration tools.
                      Let's hope your 'overdrive' is digital!

                        Even this can be used IF
                        First normalize to "0" so all the cropped peaks are at max then apply the Noise reduction / Clip restoration and some good relief can be obtained. Not perfect!

                          I've never had much luck myself with 'de clipping' analogue distortion --especially if the analogue overdrive introduces non linear dirtortion.
                          The harmonic distortion doesn't appear as a nice 'clipped' waveform suitable for restoration, but rather as complex odd harmonic distorted waveforms, below the clipping threshold.

                          Must give your idea a try--although, as you say, it's not going to be perfect!!
