Any have a simple way to correct LP skips once recorded to CE? Would be glad to find out

Hi Jeff, we need more details in regard of your problem. Is it computer related or the skip is originally from the LP itself?

When I first got Cool Edit 96 I had to repair a bad skip on a 45. I'm still not sure how I was able to repair it because it was so tricky, but if it weren't for Cool Edit's easy and intuitive sditor I couldn't have done it.
I listen to that track over and over and am still amazed at how well a job I did!

Jeff, if the skip is on the LP itself, then it would also help us to know whether you mean:
A. a portion of the track repeats, then eventually you blew lightly on the tonearm or something, and got past that, or
B. a portion of the track was skipped- over, meaning lost to the recording.

Hi Jeff,
Believe it or not a technique I've been using for years (although tedious at times) to "correct" the LP skip itself is to gently glide my fingernail tip edge (usually my thumbnail) carefully and with very little pressure (depending on how deep the scratch is) along each of the grooves in the area in and around the scratch. If you do this make sure your nails (make sure they are long enough) have smooth edges. Also be sure to wash your record afterwards.
You can't get rid of the noise from the scratch (it may be lessened somewhat), but you can prevent the skip. If the scratch is deep, it is almost hopeless then.
If you have a steady hand this works well.

I know exactly what you mean beetle. There have been times when I achieved the result I was looking for but it took so long and I tried so many different things that I dont remember how I did it.

Assuming we are talking about mechanical problems here (and nothing to do with buffering or anything like that in CEP) then there are several possibilities open to you, any combination of which might work (or none, if you are unlucky).
First, can you re-transfer the disc? If so, then this is probably the most efficient and quickest solution. If there is a broken wall and the stylus skips a groove or two, then determine which direction it is going and try applying a very light pressure to the cartridge in the opposite direction at the point where the skip occurs.
There's plenty of ways of doing this, I use a small, camel hair, artists paintbrush - the spring in the hairs is enough to overcome a lot of problems like this.
If this is not enough, try increasing the tracking weight (check the maximum allowed by the cartridge, you don't want the cantilever bottoming out) and record just the bad section, you can edit the bits together at a later time.
If the problem is with the stylus being thrown out of the groove, then increasing tracking weight by raising the mass of the headshell might prove more effective than moving the counterbalance - I use one or two peseta coins for this, you might have to find something else.
Another trick you can try is transferring at a lower speed - resampling afterwards to get back to the correct pitch.
Incidentally, both of these last tricks are very useful when a record is warped.
If you can't do another transfer for some reason, then it gets a little trickier.
First, try and determine if the skip/s are backwards or forwards. If backwards (and you have manged to get the offending parts to play, at least once, properly) then it simply a matter of editing out the poor takes.
If it is a skip forwards, then you have a real problem, since you are now actually missing material.
However, with a lot of material, it is usually possible to find another section of the recording which contains the missing part (especially in popular music, where there is a lot of repetition anyway). If can find such a repeat, then copy it and paste it back into the damaged section.
You'd be surprised at how far you can take this if you are prepared to spend a bit of time and effort. I have even rebuilt introductions that were missing from 78's with bites taken out of the edge.
If a part is repeated but there has beeen a key change somewhere along the way, you can take out the repeat section, resample to get back to the original key and cut it back to replace the bad section.
As with any editing of this nature, the secret is to edit close - thereby keeping as much of the original as possible - consistant with being able to 'hide' each cut.

If your tonearm is equipped with an anti-skating adjustment (linear tracking tonearms won't have this), try turning the dial and using settings at both ends of the dial. The anti-skating feature actually is a tension controllable light-weight spring connected to the tonearm pivot that very slightly pulls the tonearm in an outward direction (from the center of the record) when set at the highest setting.

Jeff emailed me earlier and I gave him a lot of the same ideas Graeme later suggested. (A very complete explanation Graeme, and I like the paintbrush idea; I had suggested a feather or cotton ball.)
** I just checked email again and Jeff has replied that "The ole penny on the tonearm worked fine". So it seems he has tracked through the skip now.
One other idea, not mentioned here, is manually reversing through the skip to try to lightly knock it out (not with your good stylus though). Cheers,

Although this might be worth trying, I would advise against it for several reasons;
1 It can take a long time to get anti-skating setup properly in the first place and it seems a pity to change it all, just for the sake of the odd skip.
2 It really only helps if the skip is forwards. A backwards skip would be made worse as you would be assistng the movement in the wrong direction. (Note - anti-skate devices are only ever designed to pull the tonearm away from the disc centre, there would be little point in apply a negative function).
3 The amount of additional side pressure is quite minimal and unlikely to be sufficient to overcome the problem anyway. You'd probably get more side pressure by blowing on the thing.
4 As it would be undesirable to track the whole record with the anti-skate out of adjustment, a means whereby you can apply the required amount of pressure just as the record passes through the problem section is infinitely preferable.

Most anti-skating dials have measurement increments written on them so you know the value it is set at. Just remember/record that value and set it back when you are finished with playing the record and/or section.

True, anti-skate would only work for preventing/lessening forward pulling skips. Most skips are forward skips in that you jump over a section. Too high an anti-skating value could cause back-skipping. Determining when the skip is corrected is a matter of trial and error settings with the anti-skate dial settings.

I've used the anti-skating technique to stop forward skips with successful results. I've seen some tonearms whereby if you allow it to be in the cue/floating position with the anti-skate set at max., the tonearm will eventually return to the rest (outer) position. This extreme condition can cause groove wear to the outer groove wall. I've tried using the brush technique but you need a very steady hand and need to apply consistent pressure; the anti-skating does this.

If your anti-skating wheel is not attached to the pivoting section of the tonearm, you can increase the value when you near the skip section, and then decrease it again when you've passed the skip section.
The thing you also have to keep in mind is that there are risks in damaging the stylus (especially a fine-line tipped stylus) if you do too much lateral pulling and downward pressure.

I prefer a brick so that I can listen to both sides of the record at once...

For rock & roll, you have to use firebrick, though.

I just did a vinyl-to-cd transfer which featured a couple of skips in the record. I was able to overcome these problems because these particular skips were caused by small bits of dirt stuck on the record, rather than by scratches. I carefully removed the offending bodies and was able to continue my project. When encountering a skip, the first thing one should check is, in fact, the source of the skip. Obviously, scratches are more difficult to deal with than are bits of grit.
