Oxxy, TMCD35, Bossman, Andrew C, Gibbo, Rabbieburns - WOW, you guys are amazing - thank you so much.
I will chronicle the process so others may follow along:
Making the sound - using a Technics Direct Drive turntable connected to an Onkyo 515 Pro receiver.
Capturing the sound - using the headphones jack on the Onkyo converted to mini plug and plugged into the mic/linein port on a Dell Inspiron 1525. Must convert Dell port to linein (audio preferences in Control Panel.)
Download Audacity and spend some time studying the features. The default input is mono, so go to Edit Preferences and convert to stereo (two channel). Put a vinyl on the phono, click "Record" button (be sure to set input levels) and let the system run.
Yes, there are lots of other "tweaks" that must be done, but at this point (where I am now ) music is being saved in digital format.
Bottom line - I am now confident that I can convert LP's to digital and eventually get them to MP3 format. As I learn the appropriate tweaks, I will post the cheats and tweaks that I have learned. I am not so thrilled, at this point, with the sound quality (sampling rate, bit rate - what should be used), but given direction already received from edugeek forum members, I know that the quality will improve as I learn the "ropes".
My next step will be to resurrect one of my older desktop computers, acquire an appropriate sound card and connect the turntable to that system (probably through one of the products you guys mentioned - thus a dedicated LP to digital workstation (off in a corner of the basement, so perhaps my wife won't notice it (fat chance of that ).
:D
FWIW - I am converting albums that I have collected over the past 50 years - some are available in CD's or downloads, but the majority are albums that are "out of print" e.g., digitized versions are just not available. For instance, from the 60's, I have all the vinyl editions of the Weiser Idaho Fiddle Festival - where Mark O'Conner made his debut as a fiddle player.
Guys, I can't thank you enough ... I look forward to many positive interactions with you.
