Audio distortion issues.

[video_enthusiast07]

Hi everyone, I'm having somewhat a major issue.


I recorded a movie, but I was standing too close to some major speakers at a party thus creating loud scratchy distorted audio in my video; like when speakers go bad because the input was too loud with the bass. Is there a tool to help relieve to any extent the problem?

Depends. Most likely not. Sometimes you can't remove the stain

Does it sound like this? :

Post a short clip of the audio if you can. Just 10 seconds will be enough for us to tell.

actually the distortion sound in my video doesn't sound as bad as the mp3 file I just heard.

here's a clip...don't get surprised by the music, lol its from a wedding.

I'm afraid it can't be done on this one. The distortion sounds like the microphone or the following analog circuitry was distorting. If it were moderate digital clipping it could be mostly fixed.

I have successfully restored mild digital distortion with Adobe Audition before. The program detects the level that the waveform clips at and interpolates the peak above it. It wouldn't work on your file because the distorted peaks vary in height and slope. It only works if the peaks occur at a precise level and the plateau is flat and horizontal. Also, there is distortion occurring all over the waveform, not just the peaks.

I'm sorry that it can't be fixed. At least it's not that bad. :/

Hey thanks alot for checking it out for me, I wanted to make sure on that.
and thanks also for reassuring me thats its not that bad.
Even though it can't be fixed I feel better that I don't have to worry about "what if it can be fixed" ..I'll just deal with it this time.

now I understand what you mean with waves, and next time I'll just back away from the speakers to avoid problems.


just one last question.......from what position is it better to record video when I have to deal with big speakers?

Hate to suggest this, but replace the audio with some other Polka recordings. Only the band will notice - nobody else will figure it out.

To prevent it happening in the future - number of ways you can try, depending on your microphone and recording equipment. From lowering the recording level, to using an attenuating patch cable, to a hardware compressor, to a different microphone. Start with the first 2 suggestions- that'll be cheap to test out.

I've recorded several live concerts at local clubs. I don't have top notch equipment, but I try to do the best with what I have. I use a Marantz PMD670 to record the audio separately from a pair of mics about halfway back in the room. This allows me to place the video camera for the best view. Later I'll line up the replacement audio with the video in Vegas. The DV audio is quite compressed as I can't adjust the level on the camera. The Marantz audio is nice and clean but sounds a little hollow due to the distance from the band. I usually combine the two with a little eq work and get a pretty respectable result. Here's a sample video: Soldat Brut//. It's a little dark though; I need a camcorder that does better in low light.

I assume that you probably don't have a separate stereo recorder. They are pretty expensive. You could try using an external stereo mic on top of the camera. I'm pretty sure there is a box that you can put inline to turn down the level going into the camera. I don't know what kind of camera you have, but you might try the Panasonic 3ccd user board or Camcorder Info. There is quite a wealth of useful info on those forums.

I have some audio that is mildly clipping...not enough to cover your ears and run lol but enough to be slightly annoying and tell it wasn't recorded quite right. I have Adobe Audition but I can't seem to figure out how to restore it. Does anyone know how to do this. I appreciate any help. Thanks so much!
