Editing CD ripper (section)

==Design==
As an intermediate step, some ripping programs save the extracted audio in a [[lossless]] format such as [[WAV]], [[FLAC]], or even raw [[Pulse-code modulation|PCM]] audio. The extracted audio can then be encoded with a [[lossy]] [[codec]] like [[MP3]], [[Opus (audio format)|Opus]], [[Vorbis]], [[Windows Media Audio|WMA]] or [[Advanced Audio Coding|AAC]].  The encoded files are more compact and are suitable for playback on [[digital audio player]]s. They may also be played back in a [[media player (application software)|media player]] program on a computer.

Most ripping programs will assist in tagging the encoded files with [[metadata]]. The MP3 file format, for example, allows [[ID3 tag|tags]] with title, artist, album and track number information.  Some will try to identify the disc being ripped by looking up network services like [[All Media Guide|AMG's]] [[AMG LASSO|LASSO]], [[FreeDB]], [[Gracenote]]'s [[CDDB]], GD3 [http://www.getdigitaldata.com] or [[MusicBrainz]], or attempt text extraction if [[CD-Text]] has been stored.

Some all-in-one ripping programs can simplify the entire process by ripping and [[CD recorder|burning]] the audio to disc in one step, possibly re-encoding the audio on-the-fly in the process.

Not all CD rippers read or copy [[Compact Disc subcode|Compact Disc subcodes]], a fact exploited by several types of [[digital rights management]] (DRM) to prevent successful copying of discs or to prevent effective use of software copied from discs. [[CloneCD]] is able to copy subcode data to bypass certain types of DRM.
