MP3s

MP3, is an audio coding format for digital audio which uses a form of lossy data compression. It is widely used for consumer audio streaming and music and has become the standard of digital audio compression for the transfer and playback of music on most digital audio players. The use of lossy compression is designed to greatly reduce the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original uncompressed audio for most listeners.
The compression works by reducing the accuracy of certain parts of a sound that are considered to be beyond the auditory resolution ability of most people. By using MPEG audio coding, you may shrink down the original sound data from a CD by a factor of 12, without losing sound quality. In addition to the actual music files, the creator can also add important information about the music by using an ID3 tag. An ID3 tag is a metadata container most often used in conjunction with the MP3 audio file format. It allows information such as the title, artist, album, track number, and other information about the file to be stored in the file itself.

MP3 technology was created by several developers of the Moving Picture
Experts Group MPEG most notably, Karlheinz Brandenburg, a professor at Ilmenau Technical University at the Fraunhofer Institute for Digital Media
Technology in Germany. The immediate predecessors of MP3 were
"Optimum Coding in the Frequency Domain" (OCF),and Perceptual
Transform Coding (PXFM). Brandenburg became an assistant professor at
Erlangen-Nuremberg where he continued to work on music compression with scientists at the Fraunhofer Society until the technology was finalized in 1994.

Although they are a huge technological advancement, MP3’s are not without limitations. When performing lossy audio encoding, there is a tradeoff between…...

Mormons in the 1830's and 40's

...Justin Dosey Mormons in the 1830’s and 40’s The United States of America is said to be an “International melting pot,” inhabited by a number of culturally diverse people. Each and every distinct group has played their part in the development of nation whether ‘twas good or bad. I believe that the members of “The Church of Jesus Christ of Latter Day Saints,” (otherwise known as Mormons) have proved to be crucial to the growth of the U.S.A. in every aspect. After the establishment of religion in 1827, Mormons have been the target of persecution and discrimination by many. The bulk of this persecution occurred in 1836 when a group of rebel militia attacked Mormon headquarters located in Northern Missouri. This ambush against the Mormons sparked an onslaught of hate crimes to come. After being exiled from Missouri and Illinois, Brigham Young led an intrepid party of immigrants into the Great Salt Lake valley in 1847. The population grew rapidly, and by 1849, the Mormons had managed to form a civil government with Young at the helm. This brief summary has set the stage for this report, where I will evaluate Mormons of the 1830’s and 40’s and enlighten you on their beliefs, culture, and impact throughout American History. Establishment of Religion The establishment of the LDS church is a very interesting story that many people do not understand. “In the spring of 1820, a 14-year-old boy named Joseph Smith went into a grove of trees near his home in Palmyra, New York...

Mp3 Players in the Classroom

...Mp3 Players In the Classroom By: Angel Larson, Jessica Gallo, Ashley Dorzok and Michael McClanathan We questioned if MP3 players should be available to students at Moraine Park Technical College. If so, would they improve productivity and student morale? Since many students already use their MP3 players when doing homework and/or listening to reading material for school, we believe the chances for MP3 players being used will continue to grow. Should college students at Moraine Park Technical College be awarded a MP3/iPod player to use throughout their educational career? Would having the ability to download audio books, learning materials, and/or podcasts enhance students’ learning, or become a distraction and hinder it? The purpose of our research is to decide if MP3 Players should be available to Moraine Park Students and whether it will improve productivity and student morale. Variables used will include resources and a survey given to our demographic. Our hypothesis is that productivity will increase greatly if iPod’s/MP3 Players were provided to students at Moraine Park Technical Colleges. These devices can be used to store books, lecture notes, and class videos. They are portable; making it easy to carry in a backpack, purse and often times, pockets. Students and Instructors can take advantage of these devices by uploading appropriate lesson plans and study guides to their MP3 players. While music and audio books enhance concentration, we......

Mp3 Project

...Report of the MP3 Project | | Report to Financial Manager Introduction This report is intended to outline the feasibility of the production of a new MP3 player, as laid out in the capital budgeting model provided. While the model itself is an abstraction and a simplification of the process, the intention is to produce an accurate estimate of the economics of production. Our model is a cash flow based appraisal techniques as a success of any business can partly be determined by its capacity to generate positive cash flows. Assumption Process This patent of the cutting-edge MP3 technique we currently possess will position us strongly for the next five years, and while competition is likely to increase our advertising spending projection reflects our assumption that the product will be very competitive. Heavy upfront costs will, however, need to be invested, in order to reach the achievable unit volume of 1,000,000 per year for the first five years. As a result, we are looking at implementing an advertising campaign: the first year will involve a standard $850,000 advertising budget, but with the intention of reducing this level by 15% per year given that momentum has been built. We will also have another advertising expense that will depend on the number of units sold, costed at $7/unit. From a fixed cost perspective, we expect $17,500,000 per year. New manufacturing equipment for this project is expected to $150,000,000, which can be depreciated straight line......

Mp3 vs Analog

...Analog VS. Digital Music From phonographs all the way to mp3 players, music has had a huge impact on how each decade perceives and listens to their favorite songs and recording artists. The phonograph was first invented in 1877 when Thomas Edison attempted to improve the telegraph transmitter and realized the movement of the paper tape through the machine resembled spoken word when played at high speeds. Edison used a hard pointed instrument along with a tinfoil cylinder and spoke into the device “Mary had a little lamb,” soon realizing he was able to play it back. Without meaning to, Edison opened the door to the future of the music industry, making it possible for musicians to record and distributes their original work. 50 years later vinyl records would come into play, and by the 1950’s they were your main source to listen to music. Vinyl Records were most popular from the early 1950s’ to the 1980’s until Sony developed the first digital audio recording devices to be used by professional studios. The following year, Sony invented the portable Walkman cassette player, selling over 100 million in the first year. In 1988 Sony came out with the compact disc that would be the first use the new available digital format MP3, software that compresses and decompresses audio files.( "Digital vs. Analog Audio: Which Sounds Better?") This would set off the digital audio player revolution that achieved tremendous success when Apple’s iPod was released in 2001. The advancement of......

Memo for S-S Technologies

...Memo for S-S Technologies a) S-S Technologies’ organizational purpose is for manageable growth, focusing on products within the company’s scope and skills. b) Using the framework in CoCo’s guidance on control to evaluate S-S, in my view, the control system of S-S is not efficient in some area. Firstly, from the aspect of purpose, s-s has its objectives, but as we can know from the consultants’ interviews, few employees were aware of SST’s goals and strategies. SST also don’t have specific policies to support the achievement of its objectives, for instance, there was no policy regarding bonus or merit pay. Secondly, from the aspect of commitment, SST has high commitment and employees loved the work environment. However, as we can know from the consultants’ interviews, the responsibilities are not clear among the managers or workers. Some employee felt cheated because SST could not afford to pay bonus. Thirdly, the employees in SST do have necessary knowledge and skills and knew whom to contact for technical information. However, in terms of performance appraisal, it was not done at regular intervals, people also don’t know whom to contact about benefits and salary ranges. The decisions and actions of different parts of the SST are not coordinated. What’s more, it doesn’t have efficient monitoring processes. SST can’t reassess its related information systems as condition change. c) Example of market: in early 1990, the North American economy was in a......

1930's

...National Commission During the late 1800’s there was an intense rivalry between professional baseball leagues. A National Agreement was signed by the different leagues to govern relations between rival major leagues. After that agreement fell apart, a second agreement was signed in 1904, which ended the two-year war between the National League and the upstart American League. This legislation that was passed contained a formation of a commission. They created a National Commission to settle disputes regarding player contracts and arrange for an annual post-season championship series. This turned into the start of the World Series. This commission consisted of a chairperson, the American League president, and the National League president. Only the chairperson himself was given a salary by the National Commission. The other members of the commission being the National League president and the American League president served on the National Commission without compensation. Some of the powers of the commission were to interpret and carry out the terms and provisions of the agreement while also being able to enact and enforce fines and suspensions. One of the major roles of the commission came whenever a National League or American League club claimed the services of the same player. The Chairman of the Commission decides the right to that player. The Chairman shall make said decision without the help of his two associates. If the Chairman of the Commission and the major...

The Social Events of the 1950's, 60's, 70's, 80's, and 90's

...The Social Events of the 1950's, 60's, 70's, 80's, and 90s Introduction Over the past 50 years, there have been many changes within the social movement in the United States. Some of these changes have been for the better and some not so great. These changes were made with the hopes and dreams of making life better for all cultures, species, families, and environment. Now the question is, how did these change come about, and what were these changes about? Social Life of the 1950's In the early 1950's was a new beginning for the United States. With the end of the Great Depression and World War II, people felt that they could start living, and have things they thought they would never have, like a home, cars, a wife or husband, and children. With the new beginning, families started moving from large city life to the suburbs, for the reason that life in the suburbs was considerable less hectic and peaceful than what city life was like. Due to the Great Depression, many men and women put off getting married or starting families for the reason of lack of money or homes, and with the War, many were afraid they might not come home. However, with the new feeling of security and peace couples were able start the family they always wanted and so began the Baby Boom years. People moving to the suburbs......

Do´S and Don´T´S

...Term paper: Do´s and don´t´s Space is critical. 20 pages is exclusive of appendices and references, so try to condense information in tables, figures etc. and include in the appendices (so that they don´t count in your 20 pages). Don´t waste space by including maps etc. in the text. Don´t exceed 20 pages – if you do, it will not be graded; it is not a question of characters – 20 pages is 20 pages (not 38, as in one case) It is not a good signal if you only can manage 10 pages. Don´t waste space between questions, use type 12, normal spacing. Use end notes or footnotes to conserve on space Don´t use up space in re-formulating the case in a prologue – I can remember what I wrote. Only include “need to know” – you do not have time for “nice to know” background information Don´t worry about making links from one group member´s answers to another (but you can within your own personal questions) – otherwise, treat each answer as a separate answer (as grades are individual) Language: It is not an English literature course – but naturally, your ability to formulate yourself nicely helps.
