There are a lot of turntables that can convert vinyl to mp3/wav files. The TTUSB was the first turntable way, way, waaaay back to have this capability
The TTUSB is a unique, plug and play, USB compatible turntable that makes digitizing your vinyl record collection to your PC or Mac a snap. Packaged with all the necessary cables to connect with a computer or stereo playback system, the TTUSB is a comprehensive package that breathes new life into older recordings.
As an added benefit, the TTUSB also includes a 1/8–inch stereo mini jack input connector to facilitate the transfer of cassette tapes (or similar line level sources) to computer files–making this unit the perfect tool for archiving older recordings, regardless of their original format. Export your analog music to popular digital formats such as WAV or MP3, and turn your old, forgotten records to the top of your digital music playlist.
