I was thinking about buying one of those USB turntables to record alot of my old albums to MP3. Then I found some software to record it for free and how to hook my turntable and amp up to the puter. I guess I don't have to buy the USB turntable after all.
I must have close to 500 albums from the 70's and 80's and most of them never made it to a CD. I'm gonna try it tomorrow then I'll post how it went...

I'd love to know! My albums go back a "few" years beyond yours! I bought my ex (from the kids) one of the USB turntables for Christmas, but would like to know what you work out!

You just need a pre-amp input converter so the analogue signal from the turntable matches the input voltage and impedance of your computer's soundcard. most component stereo systems with a "LP-in" can pre-amp to "aux outs" that will patch right into your soundcard via a dual RCA to 1/8" phono stereo cable.  |

A couple of my family members just bought one of the turntables you mentioned. They are going to start converting albums today, so I will tell you how it went when they are done.

I have done this. The regular output from the amp on my setup seemed to overpower the computer sound card and the final sound was greatly distorted. The output directly from the turntable to the sound card wasn't strong enough for any reasonable result. LCARS is right. You need the output from a pre-amp. What I did was feed the turntable into a reel to reel tape deck that had a built in pre-amp designed for turntable input. The tape deck had fully adjustable input and output controls and sound meters on both channels. The output from the tape deck which normally would go to the input of an amplifier now went to the computer sound card. Very excellent results this way.
I also have some software, if I remember right called Audio Medic, I'll know for sure when I get home tonight. It converts the analog audio into digital which can be burned on a CD. It has an equalizer that lets you adjust to your heart contents what the final audio sounds like. It also can eliminate hiss, crackle, pop, scratch noise. These are adjustable to degree of noise reduction. Unfortunately, at high degrees of noise reduction, the sound quality is somewhat reduced, so, as always, there is trade off. The noise reduction, while not perfect, works surprisingly well. The final digital audio is an equalized, processed, and noise reduced version of the original, and, I think, if everything is adjusted right (a big if), actually sounds better than the original LP!
Good luck with your attempts!

The thing to watch out for is that phonograph pre-amps do not have a flat response, they need to have what is called the RIAA correction curve applied to the signal.
Any stereo unit with a phono or LP input will have that circuitry, so as other have pointed out- using the tape out or aux out from a receiver or pre-amp will do the trick, but going directly from an LP to a computer or tape deck isn't going to sound right at all.

I got it all working! I just used one of my old amps and a Technics turntable. I tried some software called Audacity thats free, but couldn't get that working very well so I used Free Sound Recorder, www.sound-recorder.biz/It works and sounds pretty good. I thought all my albums would have sounded like crap but they are in great condition. Now I get to listen to Frank Marino and Mohogany rush again.... |

Hey, a fellow jeweler takes his computer, and hooks it up to his amplifier. He then clips the leads to his body. He modifies the signal by using his turntable in parallel.
He claims that aliens have infected his body and by using square wave technology he is able to flush out the nanotech parasites that are making him think things.
Apparently, the sine waves short out the parasites. Effectively making an alien/Electricals flush. He has to change the signal and power output as the nanotech parasites are capable of morphing to adapt.
I keep telling him, why not just plug himself into a wall socket for a bit, and have someone knock him off. Why play slap and tickle with the aliens? Give them raw voltage!
Those old vinyls are GREAT! Especially the photos. There is a lot of history there.
