For example, audio tracks on such media cannot be easily added to a personal music collection on a computer's hard disk or a portable (non-CD) music player. Also, many ordinary CD audio players (e.g. in car radios) had problems playing copy-protected media, mostly because they used hardware and firmware components also used in CD-ROM drives ...
fre:ac, a CD extractor and audio converter. 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).
An entire multi-track audio CD may be ripped to a single audio file and a cue sheet. However, software audio players and hardware digital audio players often treat each audio file as a single playlist entry, which can make it difficult to select and identify the individual tracks. A common solution is to split the original audio file into a ...
The track is truly hidden in the sense that most conventional standalone players and software CD players will not see it. Such hidden tracks can be played by playing the first song and "rewinding" (more accurately, seeking in reverse) until the actual start of the whole CD audio track. Not all CD drives can properly extract such hidden tracks.
On early audio CD players that were released prior to the advent of the CD-ROM, the raw binary data of CD-ROM was played back as noise. To address this problem, the subcode channel Q has a "data" flag in areas of the disc that contain computer data rather than playable audio. The data flag instructs CD players to mute the audio.

AAD is the SPARS code (highlighted in red) on Madonna's 1990 album, The Immaculate Collection. The SPARS code is a three-position alphabetic classification system developed in the early 1980s by the Society of Professional Audio Recording Services (SPARS) for commercial compact disc releases to denote aspects of the sound recording and reproduction process, distinguishing between the use of ...
Copy Control also does not prevent copying a disc by recording it as analog audio through a computer's sound card, which only causes a slight degradation in audio quality. More substantial is the loss in recording speed. This weakness, inherent in all digital copy prevention systems, is known as the "analog hole". As an alternative that does ...
Slysoft's AnyDVD program, which removes copy protection from DVDs and Blu-ray discs, also defeats DRM on audio CDs. When active and an audio CD is inserted, AnyDVD blocks the PC from accessing any session but the audio, rendering data sessions unreadable and preventing the installation of malware such as XCP. [16]
