A:Answer None of them. All of our turntable requires connection to a computer and the use of an audio recording and editing program, such as the Audacity brand sound recording and editing program that we bundle with our USB model turntables, to transfer vinyl to digital. Audacity could also be used to convert cassette tapes to digital. To do this, the tape player would be connected directly to the computer, it would not be connected to the turntable in any way. If you are in need of a 3-speed model (331/3, 45 and 78 rpm), your choices are either the AT-LP120-USB or AT-LP1240-USB direct-drive manual model turntables.
