Topic: Need help removing buzz

[blu666z]

Pulled out a tape to transfer today that sounds real nice expect for some kind of buzz.  This was the first time I had run myTLs and I am thinking I might not have had the XLRs clicked all the way in.  What is the best way to try and remove the buzz?

Cool Edit Pro has this feature where you select a portion of the file where the only thing you hear is the "buzz". Then you can load a profile of that sample and it will remove it throughout the entire sample.

Off the top of my head, look in Effects > Noise Reduction. It's not the Hiss Removal tab, but the other one like it.

In Cool Edit, select an area that is just the buzz, no music or anything...

Click:
Effects>
NR>
NR>
Get Profile from Selection>
OK


Then select the whole wav and do the same thing except don't choose "get profile", just click ok.  It usually works pretty well for me.  Although I usually use it for :60 commercials.  Not sure how it will affect the integrity of a recording.

you can adjust the amount of removal too with that setting. play around and you should be able to find the right amount of compromise.

Problem is I can't find a section that is the buzz only...everything has at least a little crowd noise...even getting the quietest part as my Profile makes it sound pretty hollow when appllied to the whole WAV.

What s/w are you using?  If CEP/Audition, check out the Help file.  There's some good info there about setting FFT, applying NR multiple times at low percentages vs. one big application at 100%, tweaking the NR profile manually, etc.  IME, takes lots of trial and error and don't expect to remove the sound outright - only hope to minimize it.

Unfortunately, I can't listen to the sample on my work laptop, but...maybe a notch filter will help?  No idea as I haven't heard the buzz, but...might be worth checking out.

i wonder how it would sound if you "notch eq'ed" 60 Hz and all of it's octaves?  not sure if it's possible with his software though.  I've read some articles about people actually doing this.  removing exactly the 60Hz, 120Hz, 240Hz, and so on with some various results depending on how much buzz present there is in the recording.

this is assuming this a ground loop electrical buzz, of course.
