Remaster (and its derivations, frequently found in the phrases digitally remastered or digital remastering) is a word marketed mostly in the digital audio age, although the remastering process has existed since recording began. The measure of its success depends on: 1. The skill and experience of the Mastering Engineer staff. 2. The equipment used for the process. 3. The quality of the original source recordings.

Remaster (and its derivations, frequently found in the phrases digitally remastered or digital remastering) is a word marketed mostly in the digital audio age, although the remastering process has existed since recording began. The measure of its success depends on: 1. The skill and experience of the Mastering Engineer staff. 2. The equipment used for the process. 3. The quality of the original source recordings. Frequently advertised with regard to CD and DVD releases, remastering has become a powerful buzzword in multimedia industries, and it generally implies quality enhancement of sound and/or picture to a previously existing recording (frequently designed to encourage people to buy a new version of something they already own). For example, the reissue boom that began in the mid-nineties saw remastered versions of the back-catalogues of KISS, The Who, The Byrds and others, while remastered editions of first-generation DVD releases are similarly bestsellers. Despite its status as an industry buzzword, however, remastering actually refers to a fairly distinct process, one that does not inherently include the notion of a positive or neutral upgrade.
Mastering
To understand the concept of remaster it is beneficial to understand that often a pyramid of copies would be made from a single original "master" recording which might itself be based on previous recordings (for example sound effects might have been added from copies of sound effect tapes similar to sampling on modern today to make a radio play for broadcast; of for example, a door opening, someone supposedly being punched, falling down the stairs, a bell ringing etc)
A master is the recording which experts state will be the definitive copy that is duplicated for the end user usually into other formats i.e. LP records, CDs, DVDs etc..
Problematically, several different levels of masters often exist for any one audio release. As an example, examine the way a typical music album from the 1960s was created. Musicians and vocalists were recorded on multi-track tape. This tape was mixed to create a stereo or mono master. A further master tape would likely be created from this original master recording consisting of equalization and other adjustments and improvements to the audio to make it sound better on record players for example.
More master recordings would be duplicated from the equalized master for regional copying purposes (for example to send to several pressing plants). Pressing masters for vinyl recordings would be created. Often these interim recordings were referred to as Mother Tapes. All vinyl records would derive from one of the master recordings.
Thus, mastering refers to the process of creating a master. This might be as simple as copying a tape for further duplication purposes, or might include the actual equalization and processing steps used to fine-tune material for release. The latter example usually requires the work of mastering engineers.
With the advent of digital recording in the late 1970s, many mastering ideas changed. Previously, creating new masters meant incurring an analogue generational loss; in other words, copying a tape to a tape meant reducing the signal-to-noise ratio. This means how much of the original intended "good" information is recorded against faults added to the recording as a result of the technical limitations of the equipment used (noise) (e.g. (tape hiss, static, etc.). Although noise reduction techniques exist, they also increase other audio distortions such as azimuth shift, wow and flutter, print through and stereo image shift.
With digital recording, masters could be created and duplicated without incurring the usual generational loss. As CDs were a digital format, digital masters created from original analog recordings became a necessity.
Remastering
Remastering is the process of making a new master for an album, movie, or any other creation. It tends to refer to the process of porting a recording from one analogue medium to another digital one, but this is not always the case.
For example, a vinyl LP originally pressed from a worn-out pressing master many tape generations removed from the "original" master recording could be remastered and re-pressed from a better condition tape. All CDs created from analogue sources are technically digitally remastered.
The process of creating a digital transfer of an analogue tape re-masters the material in the digital domain, even if no equalization, compression, or other processing--is done to the material. Ideally, because of their high resolution, a CD or DVD (or other) release should come from the best source possible, with the most care taken during its transfer; this does not always happen.
Additionally, the earliest days of the CD era found digital technology in its infancy, which sometimes resulted in poor sounding digital transfers. The earliest days of the DVD era were not much different, with early DVD copies of movies frequently being produced from worn prints, with low bitrates and muffled audio. When the first CD remasters turned out to be bestsellers, companies soon realized that new editions of back catalogue items could compete with new releases as a source of revenue. Back catalogue values skyrocketed, and today it is not unusual to see expanded and remastered editions of fairly modern albums.
Original master tapes, or something close to them, can be used to make CD releases. Better processing choices can be used. Better prints can be utilized, with sound elements remixed to 5.1 and obvious print flaws digitally corrected. The modern era gives publishers almost unlimited ways to touch up, doctor, and "improve" their media, and as each release promises improved sound, video, extras and others, producers hope these upgrades will entice people into making a purchase.
Criticism
While digitally remastering films or audio does generally improve their visual and/or sound quality, it is not always appreciated by everyone. Many remastered CDs from the late 1990s onwards have become casualties of the loudness war, where the average volume of the recording is pushed ever higher at the expense of dynamic range, making the new remastered version sound very different than the original one. This is unnecessary; in fact, reduced dynamic range often decreases the likelihood of repeat listening, often without the listener realizing why.
