 example, music and speech have been recorded and preserved by phonographic technology (e.g., record players), magnetic technology (e.g., cassette tapes), and digital technology (e.g., compact discs). As audio storage technology progresses, many challenges need to be overcome to optimize the quality and storability of audio signals.
For the archiving and broadband transmission of music signals, lossless reconstruction is becoming a more important feature than high efficiency in compression by means of perceptual coding as defined in MPEG standards such as MP3 or AAC. Although DVD audio and Super CD Audio include proprietary lossless compression schemes, there is a demand for an open and general compression scheme among content-holders and broadcasters. In response to this demand, a new lossless coding scheme has been considered as an extension to the MPEG-4 Audio standard. Lossless audio coding permits the compression of digital audio data without any loss in quality due to a perfect reconstruction of the original signal. Marketed products commonly require some type of marking on the product for commercial, regulatory, cosmetic or functional purposes. Desirable attributes for marking include consistent appearance, durability, and ease of application. Appearance refers to the ability to reliably and repeatably render a mark with a selected shape, color and optical density. Durability is the quality of remaining unchanged in spite of abrasion to the marked surface. Ease of application refers to the cost in materials, time and resources of producing a mark including programmability. Programmability refers to the ability to program the marking device with a new pattern to be marked by changing software as opposed to changing hardware such as screens or masks.
Anodized metal articles, which are lightweight, strong, easily shaped, and have a durable surface finish, have many applications in industrial and commercial goods. Anodization describes any one of a number of electrolytic passivation processes in which a natural oxide layer is increased on metals such as aluminum, titanium, zinc, magnesium, niobium or tantalum in order to increase resistance to corrosion or wear and for cosmetic purposes. These surface layers (also known as “anodic oxide layers”) can be colored or dyed virtually any color, making a permanent, colorfast, durable surface on the metal. Many of these metals can be advantageously marked using aspects of the instant invention. In addition, metals such as stainless steel which resist corrosion can be marked in this fashion. Many articles manufactured out of metals such these as are in need of permanent, visible, commercially desirable marking

As audio storage engineering build up, many challenges want to be overcome to optimize the quality and storability of audio signal. 
 For the archiving and broadband transmittance of music signals, lossless reconstruction is becoming a more important feature than high efficiency in compaction by means of perceptual coding as defined in MPEG criterion such as MP3 or AAC. Although DVD audio and Super CD Audio admit proprietary lossless compression scheme, there is a demand for an open and general compression schema among content - holders and broadcasters. In response to this demand, a new lossless coding scheme has been considered as an extension to the MPEG-4 Audio standard. Lossless audio coding permits the compression of digital audio data without any loss in timbre due to a arrant reconstruction of the original signal. Marketed products commonly command some type of marking on the product for commercial, regulative, cosmetic or functional determination. Desirable attributes for marking admit consistent appearance, durability, and ease of application. Appearance refers to the ability to reliably and repeatably render a mark with a selected shape, color and optical concentration. Durability is the timbre of remaining unchanged in spite of abrasion to the marked surface. Ease of lotion refers to the cost in materials, time and resources of producing a mark including programmability. Programmability refers to the ability to program the cross off device with a new traffic pattern to be marked by changing software as oppose to changing hardware such as screen or masks. 
 Anodized metallic element articles, which are lightweight, impregnable, easily shaped, and receive a durable surface finish, have many applications in industrial and commercial goods. Anodization describes any one of a number of electrolytic passivation processes in which a natural oxide layer is increased on metallic element such as aluminum, titanium, zinc, magnesium, niobium or tantalum in order to increase resistance to corrosion or tire and for cosmetic purposes. These surface layer (also known as “ anodic oxide layers ”) can be color or dyed virtually any color, making a permanent, colorfast, durable surface on the metal. Many of these metals can be well marked using aspects of the instant invention. In addition, metals such as stainless steel which resist corrosion can be score in this fashion.
