There is no getting around baby sitting the process. I've digitized my LP's using software, which makes the process easy nevertheless; and, the software is so straight forward there is very little chance that you will make any sort of error which will compromise the sound of your digitization.
That software is Roxio's Easy LP to mp3, which requires absolutely no understanding of recording process to operate, just follow the step by step prompts; and, the finished product will only be distinguishable from the original LP when you apply the software's pop filter to the digitization, actually making your digitization sound better than the LP it was produced from.
The software comes with an ADC so you will only need to route your turntable's output to preamp and from preamp to ADC. Then just record a wav file, separate tracks, burn to a CD, and rip the CD to your computer's music player, using the music player's automatic capability to identify and label tracks, instead of using the software's track labeling feature, which would require some time consuming manual input.
After you get the process down pat, you can expect an average time of about 80 minutes from start to finish for a very complicated gapless recording, most of your time being spent on finding the best place for track separators. For LP's having greater physical space between tracks, your total time will be about an hour, more or less.
Finally, some here advise against digitization, claiming the digitization is 1. not necessary since records will not likely wear out, and 2. the digitization will not sound as good as the record. Well, records can indeed wear out; and, digitization can actually sound better than the LP, as the LP's distracting pops can be filtered. But, the best reason of all for digitization is it gives the music mobility, to enjoy on any of your devices, anywhere in or out of your home. So, the questions are: what is your leisure time worth, and would you rather do something else with that precious time that could be more meaningful to you?
