CD Ripper software will digitize the audio and place it where  you tell it to.  I don’t know of one that won’t rip directly to a flash drive if you tell it to.  I’ve even used Windows Media Player to do this (but in that case I had to convert the output format to what I wanted after it was digitized).

CDs are already digitized, you are just copying them form the D and converting them to the format of your choice with the proper software.

Thank you Brian.  I clicked on your link, but did not see a way to transfer audio files to a flash drive as they are being digitized.  I think a piece of hardware must be necessary to accomplish that, something a flash drive will plug in to like the NAXA Portable Recorder & Cassette Player I use to digitize cassettes.
