Vinyl Repair Help

I'm working with two copies of the same album, and they both have the same flaw in the same position. In this case, I can't swap audio from one rip to the other. It's disappointing because I'd otherwise have a flawless digital copy.

I've tried interpolation, pencil editing and a generic declicking filter, but so far nothing worked. I'd say it's a lost cause, but someone here always proves me wrong.

Can anyone help?

Here's the clip. The flaw is in the left channel at sample 44,100.

[!--sizeo:1--][span style=\"font-size:8pt;line-height:100%\"][!--/sizeo--]You did 90% percent of the job by finding the click. After I've redrawn the waveform, a tick near the indicated 1s position remained (44,802). It seems part of the programme, because later 2 or 3 similar ticks occur. It too can be removed by using Sound Forge - Click Replace.

I'm not sure what result did you expect.[/size]

Whatever you say, man. I must need to learn basic counting.

There are two not very large clicks there, fairly  close together. They are very simple to remove with CoolEdit/Audition’s manual click repair. Simply select and push the button. A selection of one sample somewhere around the center is sufficient. I used FFT Size 128, Pop Oversamples 20, Run Size 25, which I find good for maybe 70% of what’s on the average LP.

I also repaired it by selecting a small region around the larger of the two clicks (nine samples selected, both channels at once), and deleted. That is far less than 1 millisecond. You will never hear anything missing, except that the click is no longer there. The second, smaller, click isn’t audible (to me) and can easily be ignored. Maybe it isn’t really a click, but it seems to make no difference whether there or not.

I'm still hearing it - even with the suggested repairs. Maybe it's because I'm wearing headphones at high volume. I might have to just settle for a reduction and move on.

Thanks for the help.

Properly repaired, there is absolutely nothing left to hear. Perchance you are fixated on something not an actual click.

I've had a look at this too.  To me there are two clicks before the first snare hit - one large one predominantly in the left channel, and one smaller one affecting both channels.  There also seems to be a series of clicks after the first snare hit - at least three clicks, two larger ones and one small - although I'm not absolutely convinced they're all clicks.  Listening after repair (at high volume), it's possible that there's still something there.  Once again, I'm not convinced it's a click.  More likely just the initial attack of the snare sound.

I'm inclined to agree with AndyH - you may be hearing something that isn't actually a click.  I've done a lot of vinyl repair and I can certainly repair your sample to my satisfaction.  I use Cool Edit Pro BTW.

Unfortunately, I don't seem to be able to upload my repaired version for you to listen to.

That could be the case. Or, after repairing the larger click, I'm noticing a much smaller one that's very close to it. I'll make myself crazy if I spend any more time on it, and it's not worth that since I don't hear it unless I have the headphones on.
