Depending on the capabilities of the ripping software, ripping may be done on a track-by-track basis, or all tracks at once, or over a custom range.
The software then dumps them into a WAV or AIFF file, or feeds them to another codec to produce, for example, a FLAC or MP3 file. The ripping software tells the CD drive's firmware to read this data and parse out just the LPCM samples. Some all-in-one ripping programs can simplify the entire process by ripping and burning the audio to disc in one step, possibly re-encoding the audio on-the-fly in the process.įor example, audio CDs contain 16-bit, 44.1 kHz LPCM-encoded audio samples interleaved with secondary data streams and synchronization and error correction info. digitizing audio and video originally stored on analog formats, such as vinyl records is incorrectly referred to as ripping.Ī CD ripper, CD grabber or CD extractor is a piece of software designed to extract or "rip" raw digital audio (in format commonly called CDDA) from a compact disc to a file or other output. To rip contents is also different from grabbing an analog signal and re-encoding it, as it was done with early day CD-ROM drives not capable of digital audio extraction (DAE). One can copy a DVD byte by byte via programs like the Linux dd command onto a hard disk, and play the resulting ISO file just as one would play the original DVD. When creating a copy, nothing looks into the transferred file, nor checks if there is any encryption or not, and raw copy is also not aware of any file format. To rip the contents out of a container is different from simply copying the whole container or a file. A rip is the extracted content, in its destination format, along with accompanying files, such as a cue sheet or log file from the ripping software. Ripping is often used to shift formats, and to edit, duplicate or back up media content. Later, the term was used to extract WAV or MP3 format files from digital audio CDs, but got applied as well to extract the contents of any media, including DVD and Blu-ray discs, and video game sprites.ĭespite the name, neither the media nor the data is damaged after extraction. Originally, it meant to rip music out of Commodore 64 games. Ripping is extracting all or parts of digital content from a container. This article is about copying digital media.
