Hi,

I have a video track with sound track on which somebody, during recording was sitting next to me, laughs like a sheep. It is so awfull, I want it to remove.

How can a remove a piece of audio from a track? More specific it is on 1 channel only.

You may not want to remove it, but instead replace. Find some audio in the same area with the same background noise, but no obvious sounds. Go to the beginning of the sheep laugh and split the audio track, go to the end of the sheep laugh and split the track again. Delete this segment and insert the clean audio piece you found earlier.

You might need to ungroup the a/v track so you don't split and delete the video as well.

Hi,

Thanx for the procedure.
I thought there would be a more intuitive(?) solution in VV.

What Dave siad is the only way to do it with VV alone. I'm not sure, but I think a separate plugin package called, Noise Reduction, will do this. I do not have NR, nor am I an expert at it, but it basically works like this.

1) You find a section in your audio track where there is no other sound or dialog that you want removed, but has the offensive audio.

2) You sample this section.

3) Then have NR remove all occurences in the rest of the track.

Like I said, this is only how I understand it. I have never done this before, so it may not work.

Maybe you should post this question on the Audio forum for the sound guys to figure out.

By "channel 1", do you mean "only the left channel"? If so ...

If you have Vegas 3, open the audio track in two separate tracks (if you haven't trimmed yet it should be very easy to align them). Set one track to left channel only, and the other track to right channel only. Pan the left track hard left and the right track hard right. Split the audio tracks just before and after the sound you want to get rid of and delete that section of the left track. Pan the right track to 50% left and increase the volume 5.4dB. You will now have the right channel only on both channels. (Of course, reverse the procedure if you need to elimitate the right channel.)

If you have Vegas 2, then you'll have to do some work beforehand creating .wav files with only the left & right channels.

Hi chienworks,

At first I thought what does he mean by "Pan the left track hard left and the right track hard right." , but now I understand, remembering the context menus.

Thanx I will try this too.
