I have an audio track with a bad glitch on the right channel (shown selected)

The glitch is too big and bad for the Repair tool.
It can be moderated using the "Pop Mute" effect, but that will not remove the damage, it'll just make it a bit smaller.
The best way to repair would be to make a "patch" by copying and pasting a similar piece of audio and cross-fading rapidly from one to the other. The audio immediately after the glitch would be suitable for making the patch, but it's quite a fiddly job to make a good job of patching.

Time for "EZ-Patch".

Here's I've selected the glitch and allowed a little room either side for a rapid cross-fade, then extended the selection to the right fare enough to create the patch.
Doing this manually would require multiple steps, but with EZ-Patch all that is needed is to select, then click OK.

Brilliant, yet again!

It's now in my plug-ins folder. Next time I have an LP recording with a real big glitch (too big for ClickRepair to deal with) I'll give it a try.

Hi,
I have about the same problem, but don't need the fading. How can I - for any purpose - select one, or part of one channel of a stereo file?
Tks - Frediano

Click on the name of the track and from the drop down menu select "Split Stereo Track". You can then work on the two audio channels independently.

Hi Steve,

I agree with Cwluc...

You are a miracle worker.
I just started using Audacity today and I'm taking out these loud nasty pops on a recording of a violin from the 50s and it sounds great!

I have a question about the Cross-Fade Overlap setting...

It's a percentage...but a percentage of what? The total time of the selection? Does the percentage to the total crossfade on both sides or does each side split the percentage.

Sorry for the newbie questions.

EZ-Patch is great!

It's a percentage of the "patch" (see the second picture in the first post). In other words, a % of half of the selection.

If set to 50%, the crossfade at the beginning of the patch will meet the crossfade at the end of the patch.
Usually you would want the crossfade fairly short - it's there so that the transitions into and out of the "patch" are smooth.

Does that make sense?
