A CD ripper, CD grabber, or CD extractor is software that convert tracks on a Compact Disc to standard computer sound files, such as WAV, MP3, or Ogg Vorbis.
It rips raw digital audio in CD-DA format on a compact disc to a file or other output.
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 behaviour 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.

Ripping is the process of copying audio or video content to a hard disk, typically from removable media such as compact disc (CD) or DVD, although the word refers to all forms of media. Despite the name, neither the media nor the data is damaged after extraction. Ripping is often used to shift formats, and to edit, duplicate or back up media content. Digital Audio Extraction (DAE) is a more formal phrase applied to the ripping of audio CDs. A rip is the copied content, in its destination format, along with accompanying files (such as a cue sheet or log file from the ripping software).
Ripping is distinct from simple file copying, in that the source audio or video often isn't originally formatted for ease of use in a computer file system; ripping such data usually involves reformatting it and optionally compressing it during the extraction process.
The source material being ripped doesn't need to be digital; ripping can involve digitizing audio and video originally stored on analog formats, such as vinyl records.
