Audio Pop Cleanup

msbizzee wrote on 1/11/2000, 12:54 PM
I have an audio clip with some bad sound. Right over one
spoken word, there is a "pop" which is, for all purposes a
peak. This occured in the original recording. I HAVE to
use this particular clip. (HATE THAT) I'm fairly new to
Vegas, and I have Sound Forge at my disposal as well. What
tool would be most effective in removing this pop? Can a
knowledgeable audio guru out there provide a solution for
me? Thanks.

The methodology is, first determine the fundamental frequency of
the "pop", and then use an EQ to reduce that frequency at that
particular spot ... usually a "parametric" eq works best.

Sometimes it takes a combination of frequencies. If the "pop" is an
explosive sound from breath on the microphone, try mulitple
frequencies of 40, 80, 120, 160 ... one, two, or even all of them,
will usually work to remove that type of sound.

If you can't tell the exact frequency by ear, use the "analyze"
function of some of your editing/mastering software to determine the
frequency befor you try to eq.

Hope this helps.

Do you have Sonic Foundry's Noise Reduction 2.0? We just got it and
it has a new plug-in added called Clipped Peak Restoration. Its very
good,It fixes clipped audio and you can't tell.I don't know how bad
your problem is but I think you can download a demo so you can see if
it will help you.
Hope this Helps

You could also use the compressor, called Graphic Dynamics in Forge,
to bring down the volume and soften the attack of the plosive.
There's a preset for it, which is a good place to start, and then
tweak to your heart's content. Always trust your ears!!! Hope this
helps you.

If the "Pop" is a plosive, it will be best to follow the others
advise and process with a multi-bank processor as found in Sound
Forge. If the noise is a spike created by an outside source, the
solution is different. I have a modest recording studio and the
wiring is less than perfect. When my AC comes on, it sometimes will
click in my monitors. If I'm recording at that time, I'll get a minor
spike in the audio. Take the file into Sound Forge and locate the
pop. Zoom in to that area a lot, matter of fact as large as you can.
You should notice a series of consistent waveforms on either side of
the spike. Highlight the peak of the wave on either side of the
spike. Now delete the spike. The waveform should now appear as the
others with no noticable loss on time or no audible problems. If you
still hear a noise, undo and retry until you succed. Have Fun.
