Professional CD mastering is first and foremost a decision-making process, and then of course it's about making key changes to the sound. You can kind of look at a mastering engineer as a 'third ear’ guy, an over and above producer if you will. The mastering engineer comes in right at the end of a project and needs to make key decisions, and suggestions on the overall sound and layout (song sequences, pauses, etc.) that will be presented on an album. Producers, audio engineers, A&R persons, labels and artists all trust the mastering engineer to ensure that they put out a top sounding album with maximum impact. For this reason a mastering engineer needs more than just experience in audio engineering, experience in other aspects of the industry is vital. A mastering engineer not only needs a good ear, but also a good feeling for what works and what does’t, a good understanding and feel for different genres of music, a good grasp of how to make an album ‘flow’ from the first to last track, and much more. |

Compact Disc, a digital medium formed of a 12 cm poly carbonate substrate, a reflective established layer, and a protective lacquer coating. The physical format of CDs is described by the ISO9660 industry standard. CD-Record able discs also have an organic dye data layer between the substrate and the metal reflective layer .Compact Disc-Record able. This term is used to describe the technology of record able CD as well as the equipment, software and media used to make record able discs.ross talk This is a measure of the amount of interference coming from neighboring pit tracks on a CD. As track pitch is tightened (when tracks are packed closer together to put more data on a disc), cross-talk increases. A maximum value of 50% is allowed by Red Book specifications. CyanibeOne type of organic dye used to form the data layer in CD-R discs. Cyanine was the first material used for these discs, but presently a metal-stabilized cyanine compound is generally used instead of "raw" cyanine. |

Cyanine was the first material used for these discs, but presently a metal-stabilized cyanine compound is generally used instead of "raw" cyanine. An alternative material is phthalocyanine.Data layer In CD-R, the organic dye sandwiched between the poly carbonate substrate and the metalized reflective layer of the . CD-Recordable discs do not have any data on them until they are recorded. Instead the recording laser selectively melts "pits" into the dye layer -- but rather than burning holes in the dye, it simply melts it slightly, causing it to become non-translucent so the reading laser beam is refracted rather than reflected back to the reader's sensors. In pressed CDs, the data layer is part of the poly carbonate substrate, and is pressed into the top side of it by a "stamper" during the injection molding prose's. |
