Title: Suggestions for removing a PA buzz?
Post by: KLowe on July 08, 2006, 10:39:32 PM
Hey yall.
I recently taped a local guitar duo in Huntsville, AL.  A really cool mix of a very talented old "deadhead" and clasically trained PhD in guitar.  Good stuff IMO.
They both requested a copy of the show from me for allowing me to tape..(fine by me).  Here is the problem.  During the performance the right PA buzzed like a MF'r...and is really damn annoying.  I'd like to get the guys a copy of the show with the buzzing removed.  I have audition, soundforge, and wavelab available.  How would I go about isolating and removing the PA buzz???

Any help with any program would be greatly appreciated.
Thanks in advance.

You need to find yourself a buzz/hum reduction plugin/vst or a noise reduction vst. Then experiment. They can help a lot, but it won't be perfect, and fidelity will suffer. You could always search isohunt for "vst" and go from there, but you're on your own on that front...

Try to find @ what frequency the buzz is most prominent (50 Hz, 60 Hz, etc.).  It may be possible to reduce it using a notch filter.

soundforge has a function (IIRC) wherein you can sample a section of the noiseprint and incorporate it into the reduction scheme, so that it only removes that noise...

Teddy Ray is referring to Sony's Noise Reduction 2.0c Plugin

you could always delete the right channel and copy-paste the left channel in its place. you were probably recording a mono pa anyway.

I find a spot where there is just the buzz.  Then I measure that spot using Cool Edit Pro's Noise Reduction tool.  Once measured run a few light passes of Noise Reduction .

Yeah the artists deserve to know if the venue fucked up their performance.

Probably the other way around... Most likely an guitar cabinet on-stage that was buzzing.  Removing PA buzz is tough.  Good luck.

Normally I'd guess that too but Kevin said it was the "Right" PA speaker.....not both
