"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.

There exist a number of sites with album art that can be downloaded. I looked at some a couple years ago but the only address I have handy is
http://www.recordlabels.smugmug.com/
The password was labels some time ago, but I haven't tried any access lately.

While it isn't organized for downloading into some database, you can find out quite a bit about many albums at http://www.allmusic.com/ CD data bases exist, of course, and information about using them is no doubt readily available. Try reading in EAC or one of the other DAE programs.

I would say it isn't worth while to try to record to computer at faster than real time. Using a 78RPM turntable would make for problems with the equalization, at the very least. If you want to do a decent job of cleaning up the audio, that is going to take quite a bit more time than recording anyway.

If you are at all serious about the quality of the finished product, you need to start right. Recording should be in PCM 32 bit floating point to avoid problems with processing. Audition is the best bet, but if you don't want to spend money, Kristal and Audacity will let you get the file created in a reasonable format.

Various less expensive programs have declicking and noise reduction abilities but I only know the quality of the ones I use. There are a number of inexpensive programs that satisfy some people but from what I've seen they really don't approach what can be done with the right software.

I'm not sure what you mean about "process the stuff on the fly" but are you sure your soundcard has an analog level adjustment. Most don't, they just reduce the bit depth. It does depend on the phono preamp, and the cartridge, but for most setups there is no need to adjust the level; just record what comes out of the phono preamp. And you certainly don't want to be adjusting levels dynamically, as thought orchestrating a live recording. The result would be strange.

I don't think there is any reasonable way, which is to say quality oriented way, to do something additional while recording. Record, then process. When everything is as you want in the .wav file, declicked and clean, then you can consider encoding into some compressed format.

Yes, yes, I know. I'm not considering it. I did say "it has to happen in real time, no faster" after all.

The biggest problem isn't even RIAA compensation, that can be reversed with some loss of dynamic range after the ADC.

The biggest problem is the response of the pre-amp and cartridge, and how heavy you'd have to track to keep the stylus down in the groove.

Well, given that I can provide a clean line-level signal in I think that storing in 32 float is a bit of an overkill. int 20 is more than the table and preamp can muster, and they are quite good, actually. (not very new, but good)

I would think that one could quickly go, after some simple gain ranging, to int16 without any real issues.

Processing, of course, has to happen in at least 32 int (8.16.8) if not float, of course.

I guess I'll have to think about automatic recording myself, then.
