I have a board feed from a ben kweller show. long story but the board guy from the act before messed with my setting so i coudlnt record them. my master vol is low and i have ground buzz durring the entire thing. is there a way to take out that? i would apreciate it and a copy goes to who can help. :clap:

if it's at a certain frequency you may be able to eliminate that frequency without much damage, but I presume the buzz occurs at that frequency and all octaves relative
-
maybe, i tried that but i dont know if i did that right. the buzz is at 60hz right?

with cool-edit pro, you can sample part of the WAV to build a profile, then eliminate noise with that profile from the entire WAV. I've done this before to eliminate buzz from a loose connection to the sbd. You have to be careful not to introduce weird digi-artifacts when doing this, but it does a pretty good job.

heh can you translate that to english for me? i use cool edit pro so i can sort of figure it out.

yeah, but it may also occur at octaves of 60, such as 120, 240 etc.

well, I don't speak any language other than english, so I'm not sure how else to say it :)
In CEP, there's a filter called "Noise reduction". I don't remember where in the tree it is, and my computer's off so I can't go find it. Basically, you select a portion of the WAV - find a quiet part that only has the buzz. In the dialog, you can select "create profile from selection" or something like that. Once you do that, you should be able to save that off to a file. close the dialog, go select another part of the WAV with some music, re-open the filter, and click "preview" or something like that. You may have to load the profile back from file, but I think it persists after you sample it. Then, just adjust the sliders to get the amount of reduction that sounds good without creating digi-noise.
I have found that this filter won't work on an entire 2hr wav file. It seems to be memory dependent, so you may have to proceses the wav in segments.
Is that more clear?

If you run XP you can get a program called SoundSoap that is designed to remove noise and buzz from recordings. It has a 60Hz setting and you can fine tune it.

FWIW, CEP has the same feature, as I suspect most audio editing progs do.
