How do I clear using Audition?	Can't Post

I have a graduation party where there were speeches, loud music, and a band. I used a shotgun mic on one cam and the on-cam mic for the other. Both were fine for the speeches but when the extremely loud music played it blew out the sound. I have tried ways in Audition 1.0 to remove the clipping (I think that's what it's called) but still have some in there. I used the graphic eq effect to do this. What is the best way to set the audio properly?

Unfortunately, once recorded audio (digital) clips, not much can be done to totally fix it...yes you can sometimes isolate the clipped frequencies and eliminate/attenuate them with graphic/parametric eq. Always try to keep the record level below 0db...preferably around -6db. Even with that said, the mics themselves may be the culprit as the audio simply overloaded the diaphram of the mic. Shotguns used indoors (and mounted horizontally) are useless in my book for capturing anything but spoken word (and no other competing audio)...many on camera mics are not much better (about the only one worth a flip is the stock canon XL1 mic). With most on camera mics you have to move physically away from the sound source to keep it from overloading...however, as you move farther away from the source, the dynamic range of the recording drops exponentially.... Unsure

I need to correct/update my response...I've heard Audition 2 may be able to fix the clipping (to a degree)...but from I hear it is a chore to do...

There is a lot of buzz about a new program from iZotope that can remove analog and digital overload distortion. It uses advanced multiband processing to actually rebuild damaged peaks in clipped audio....

Thanks for the responses Mark. I remember DSE a few years ago responded to a very similar question and gave some instructions on how to fix this problem. It worked for me then and I saved the info. But now I can't find it nor can a search on the forum find it. It no doubt resulted in audio not up to your usual standards but at least made it usable.

On a side note, I need to work on better capture of audio next year. I'm hoping this forum category will provide some excellant tips on accomplishing that. So far, it seems to be geared more for specific mics but during the winter months if someone like yourself could post a few comments on audio capture it would be helpful to a lot of us.

Thanks!
