CD ripper

A CD ripper, CD grabber, or CD extractor is software that rips raw digital audio in Compact Disc Digital Audio (CD-DA) format tracks on a compact disc to standard computer sound files, such as WAV or MP3.
A more formal term used for the process of ripping audio CDs is digital audio extraction (DAE).
History
In the early days of computer CD-ROM drives and audio compression mechanisms (such as MP2), CD ripping was considered undesirable by copyright holders, with some attempting to retrofit copy protection into the simple ISO9660 standard. As time progressed, most music publishers became more open to the idea that since individuals had bought the music, they should be able to create a copy for their own personal use on their own computer. This is not yet entirely true; even with some current digital music delivery mechanisms, there are considerable restrictions on what an end user can do with their paid for (and therefore personally licensed) audio. Windows Media Player's default behavior is to add copy protection measures to ripped music, with a disclaimer that if this is not done, the end user is held entirely accountable for what is done with their music. This suits most users who simply want to store their music on a memory stick, MP3 player or portable hard disk and listen to it on any PC or compatible device.

Optical drive properties
Properties of an optical drive helping in achieving a perfect rip are a small sample offset (at best zero), no jitter, no or deactivatable caching, and a correct implementation and feed-back of the C1 and C2 error states. There are databases listing these features for multiple brands and versions of optical drives. Also, EAC has the ability to autodetect some of these features by a test-rip of a known reference CD.[2]
