"ripping" LP's, how?

( I think this is the right forum, I'm trying, at least, to get this right. )

Like some other old folks here, I have a lot of LP's that I would like to move over to my computer.

There are several issues.
First, it has to happen in real time, no faster. This is quite profoundly annoying.
Second, I'd like to be able to get things like album art, etc, by entering the catalog number or something like that, or searching CD databases, perhaps, for the info, although often tracks are different, moved, or present/missing.
Third, I'd like to process the stuff on the fly, using the sound card's analog level adjustment to keep me in a decent dynamic range, but providing some space for overloads.
Fourth, I'd like to be able to run things like de-clicking, de-noising, etc.
Fifth, I'd like to stuff that all into .wma Q90

Does anybody make anything like this?

You may assume I own:
A good turntable
A good record cleaner
A good cartridge and stylus
A good phono preamp/general preamp

So I can get line level signals that are properly equalized into my sound card, in fact using balanced lines so that I can even get some noise rejection.

It isn't clear to me what kind of feedback you want. Your post seems to suggest you don't care about what might be done with the recordings, in terms of what is frequently termed ‘audio restoration,' but rather want something said about the raw recordings as is. If you have some particular questions in mind, you may get better feedback by voicing them.

The content itself is outside my experience and doesn't have many easy references for me, like piano or trumpet or a female singing sweetly. There is strong percussion and voice that seem to have been clearly recorded, but not being familiar with the pieces I can't say much more than that. Asking some questions on the Audiomasters forum, where many people with extensive professional recording experience hang out, might bring you some insights http://www.audiomastersforum.org/amforum/index.php

The disk(s) these are from appear to be in reasonably good condition. There are clicks and pops but nothing major, and the particular audio itself tends to mask much of the impulse noise. There is strong sub-sonic content but that is to be expected; filtering it out would be good. Recording A1 has a skip 1.6 seconds from the beginning, due either to a disk defect or some interference while recording -- or someone has a rather peculiar idea about what makes good music.

There isn't enough to be certain in either case, but A1 and 01 have small lead-in ‘silences' that may be from between tracks. If this is so in either case, the background noise is rather high. If these too short intervals are actually somewhere within audio tracks, the import of the measurements is less easy to determine. Also, without some reference recordings made on your system, it is not possible to answer various questions. Is the noise due to the condition of the disk? Is a major component of it from your system, independent of what disk you are playing? Was it part of the original recording that went onto the disk? How clean was the disk(s)?

There isn't any major indication of the following condition in these recordings, but the previous comment about more noise or more clicks and pops on one channel than the other suggests one important possibility: the stylus's azimuth is off. This can be because either the stylus attachment to the cantilever or the cantilever itself are not properly aligned to the vertical axis of movement within the cartridge body, and/or because the entire cartridge is rotated off the proper angle to the disk at its attachment to the head shell.

In my not too extensive but very real experience this causes the channel from the groove wall that the stylus tip is rotated away from to produce more clicks and scuffing noise that is not due to the condition of the disk itself. This can be hard or impossible to judge on a well used disk because one probably doesn't know what has been done to distort and wear it prior to your test, but the result is quite apparent if one compares recordings from mis-alignment and after proper alignment. If the condition exists, most, but not all, disks will exhibit the symptoms and it tends to be most pronounced in the first minute of either side.
