This is how I usually start in converting the analog recording from the vinyl record to digital so I can post the music on YouTube. Basically, I record the output from a tube preamp using a handheld digital recorder. Initially, I was using the Zoom H4 - the one on the right. I like its simplicity but unfortunately had to retire it as it kept crapping out. Had it maybe close to 15 years. The one on left that looks like the a mini-Transformer Robot is the H8 that replaced the H4. The H8 is ugly but has more bells and whistles. The H8 can record up to 96 kHz at 24 bit - compared to the H4 that records only at 44.1 kHz at 16 bit. I just go with 44.1 kHz at 24 bit on the H8. One of these days I'll experiment with higher resolution although I think the fidelity is likely to make no difference when listening on YouTube.
After saving the sound file, I import it to Studio One (by Presonus) where I do simple remastering by applying EQ, parallel compression, Hi-pass and Low-pass filter as appropriate. I do this so it will sound just like what I heard on my hifi system. I want to hear the low end from the subwoofer and the overheads from the tweeters. Still learning but it's been a wonderful journey to get back to sound recording - something I've abandoned for decades.
