Popping and clicking caused by editing in Sony Vegas
Hi all,
If someone can help me to solve this annoying audio edit problem I’ll be very grateful. I’m using Vegas Movie Studio 9.
I’m editing an MPEG2 video clip with a perfectly clean audio track.
The problem does not occur when the sound is left in it’s original position in relation to the video. However when I start to edit the sound, cut, copy and paste, using bits from the beginning at the end etc. a kind of popping and clicking appears, distorting the sound only in those areas in which the sound has been moved from its original position.What could this be and how can I resolve it ?

This problem is NOT caused by Sony Vegas. It is caused by you. If you do not pick exactly the right spot to “cut, copy, and paste” audio, you will produce the sounds that you describe as popping and clicking.
One way to reduce or disguise such effects is to merge the audio segements via an overlap. When you do this, Vegas will normally fade the two audio segments together. One will fade down while the other fades up. When I say this, I am assuming that you have not turned off this fade option.

Thank you very much for the reply, but this problem is not caused by the joins, it is during the moved segments themselves, and throughout them.

Sorry, but that simply doesn’t make sense unless the audio originally contained the pops and clicks. I am not aware of any audio format where the downstream audio is affected by an upstream event.

I refer you to Carl Alessi’s post on this forum…

Carl and several respondees appear to have had the same annoying problem in Vegas which sometimes occurs when audio clips are cut and pasted. So far no one has been able to resolve this.

I’ve never encountered a problem with any of the above mentioned and certainly not by cutting the audio. This is part of my process on a daily basis so I am not sure what could be the cause of you issue. I think the clicking or popping as was mentioned here is due to sudden access of the file and yes it can be avoided in that instance with a very short fade in. It is kind of like having the sound level high and then realizing you do not have the speakers turned on, press the button and instant clipping. But simply moving a file should not cause this.

It is quite easy to spot the problem and prove your case in Vegas Pro, and I suspect your version of Vegas can do the same. Simply expand the vertical size of the audio track by dragging its lower edge. Position the time line cursor near a pop or click that was not present before the split. Then expand the detail of the time line until you see the audio waveform at the sample level. You will then see what is causing the pop or click.
Find the same spot on the original audio, and compare the two. If there is a difference in the wave form then you will have proven your case, and you can post a picture of the before and after wave form. You will, of course, need to show that the surrounding area of the waveform is identical to demonstrate that you have the same spot.

Popping and clicking audio is not caused by editing. It is most likely an issue with your audio card. Make sure your audio card driver is up to date. Or, try another audio card entirely. If you have motherboard audio, try an external card or vice versa.
