Behringer has an excellent interface connector that costs about $40 and it works really well.

I suggest not doing noise removal with Audacity because it messes the sound and if you keep your records in good condition it shouldn't need any noise removal anyhow. You can get record cleaners to wipe the dust off which helps alot. If noise removal is a must, I have found the only software that will do it without distorting sound is ridiculously expensive, but I had it already (Works well for other uses too) and it works flawlessly.

Also, quick tip, set up your turntable with all your equipment before connecting to your computer. So equalizer, pre-amp, amp, so that you can adjust it slightly before you even record. As well, turntable quality makes a huge difference, even though it sounds stupid. I have tried this with a bargain basement turntable but I have access to a $12 000 turntable that floats on oil and what not...Huge difference in quality. I am not suggesting you go out and spend that much, but buying a decent turntable is a wise investment.

PS - (Don't buy the USB Turntables, they are the biggest waste of $150 you will ever find)

Put captions, please, so I can read them. I can not understand spoken English.

Thank you. I have used Audacity a very little bit, but never took the time to learn the features you showed. I need to try this with some 33 1/3 rpm LPs we own.
