How to 'rip' from LP's

i want to connect my audio system to my computer. This is order to ‘rip’ my old LP’s and copy them to CD’s. Anyone got an idea how?

Get a AUX -> 3.5 mm stereo plug and connect fron the Output on your stereo to your line-on your sound card. Then use for example CoolEdit to capture it to WAV.
