I have a many half-speed mastered LPs from Mobile Fidelity, Nautilus, CBS, and even a couple of direct to disc LPs that I would like to digital files. My current computer motherboard has a "line in" analog input from my pre-amp, and a built-in sound with an analog-to-digital and digital-to-analog converter. I am pretty sure all I need is software. I'm a complete newbie at this stuff, any advice and recommendations would be appreciated.
TIA
