Good news is that the Windows/Audacity/AT-LP120USB combo works out of the box. Bad news is that you will get, at best, adequate performance. Just remember that if you'd llke to listen to what you're doing then turn on monitoring. Not sure why you'd want it off. I digitized a couple of LPs for my sister-in-law and it's clear that the gain in the system is really high. Using the USB directly I had to turn the input to 0.15 to prevent clippin. The data stream is, for obvious reasons 44KHz by 16 bits. So if you dial in an input level that's wrong some dynamic range goes away. If you set it too high there'll be clipping.
Even this naive usage revealed turntable weaknesses. You can physically observe turntable rumble. The music in quiet passages is surfing on a few dbs of sinusoidal rumble at a few Hertz. It was really eye-opening when I applied a 48db/octave filter in Audacity at 16Hz. The underlying low frequency sine wave melted away. Thank you mister Fourier! I haven't gotten the right settings down on click removal, but if there aren't many you can actually get rid of them by hand. Takes about thirty seconds each using the pencil tool on the dashboard.
I think I've found a fix - more next time.
