The ratio between the original bit rate and compressed bit rate is the compression factor. Compression can, therefore, be termed as bit rate reduction. Compression also may reduce the size and weight of recorder, as well as relax the mechanical tolerance of audio devices.
In cinema, audio compression maximizes the number of audio channels. Consumer devices such as games, portable digital devices, and music players also have audio compression technology. Further, these devices access the internet and may play or use internet content. The sheer numbers involve necessitate the use of audio compression in the storage and archiving of this online content.
Implementing audio compression requires a good understanding of the human ear. Only a certain portion of sound is useful to the ear. This is the perceptual entropy. All other sound is redundant. The ear distinguishes certain critical frequency bands. The result is an effective Q. factor responsible for auditory masking. A detailed modeling of how masking occurs in the ear is essential to the design of audio compressors. It is vital not to exceed the masking threshold so that compression is not audible.
If compression is unnecessary, do not use it. This is because compressed data is more prone to transmission error than non-compressed data. This is because compressed data may not contain redundancy which is necessary to reconstruct lost data (Gonzalez et al. 128). If compression is necessary, the compression factor should be low. This means that the compressed data is as similar to the original data as possible....
Digital signatures are comprised of a series of algorithms and mathematical constructs that ensure the authenticity and verifiability of a person signing a specific document. The reliance on digital signatures continues to increase as virtual work teams, the development of automated contract management, compliance, financial reporting and advanced workflows in the fields of financial services continues to grow (Keenan, 2005). The intent of this analysis is to define the properties

Digital Signature Scheme Based on Factorization The objective of this study is to discuss an issue in cryptography or computer security. Digital signatures are described as "an analog of handwritten signatures" which are based on "the physically idiosyncratic way of signing one's name. But they can be easily forged." (Grabbe, 1998) The digital signature is "a mathematical method of attaching one's identity to a message" and is held to be more
Digital Privacy in an Information Technology Age Information privacy refers to the desire of individuals to control or have some influence over data about themselves. Advances in information technology have raised concerns about information privacy and its impacts (Belanger & Crossler, 2011). There are many definitions for information privacy, but there is little variance in the elements of the definitions, which typically include some form of control over the potential secondary
The technological capabilities of digital television are enormous, and the future of digital television can be seen as being on par with web pages and compact disc technology, all through the television. The broadcasting standard, however, can be traced back to the time when analogous television was first introduced as a viable medium in the time of World War II. It was in 1940 that the NTSC - National
Drawbacks and Solutions in Transitioning from Print Textbook to Digital Textbook The first challenge that this transition may face is the immediate requirement of an inflated budget intended for gadget purchase. Though print textbooks were dismissed as the cheaper option, digital textbooks do also have a considerably expensive budget to purchase and maintain. Furthermore, in cases where students were to fully sponsor themselves in the purchase of such material, division will
