MP3 is short for MPEG Audio Layer III and is a standard for audio compression which can reduce music files without reducing ( or only slightly reduced ) sound quality . MP3 is part of the MPEG family , stands for Motion Pictures Expert Group , a standard for video and audio format that uses a compression system .
In Indonesia , the MP3 format is gaining in popularity along with the proliferation of shanties in the palm and distributor of software sales . Such places usually buy and sell a CD ( compact disc ) containing songs in MP3 format . Any CD with a capacity of 700 MB can store about 200 songs . This is the privilege of the MP3 music format that distinguishes it from other music formats . The file size is relatively small so easy in storage and removal ( transfer ) .
However, not many people know about the story of the inventor , who has been combining his knowledge of mathematics , sound , and electronics - which is fabulous, do withoutexpect personal gain .
Reject funding bidThis story starts from a place called Frauenhofer Institute , one of the research institutes in Germany 's most prestigious and employs approximately 250 people graduate . They are the best German scientists and engineers , although it is reported that they received no salary greater than that offered by industry standards .
Professor Karl Heinz Brandenburg is one of the scientists working at the institute. Involvement in the field of compressed music started since 1977 . At first , Professor Dieter Seitzer - lahwho had the idea to create a method to transfer music through a standard telephone line . At that time , the idea is considered as a brilliant teroboson . However , he refused every offer that comes as a relief fund research . He instead decided to form a separate working group consisting of scientists and technicians Frauenhofer who have an interest in such topics . Keberminatan Bradenburg to mathematics , electronics , and ideas nyleneh makes them an ideal partner .
Furthermore , research on compressed music files is led by Bradenburg , and performed at the Frauenhofer Institute , a division of Integrated Circuits ( IIS Frauenhofer ) , in Bavaria . Bradenburg then decided to concentrate its efforts on passing algorithm pengompresian file . The result is an algorithm " MPEG - 1 Layer 3 " which was then shortened to " MP3 " .
The small number of similar studies that have been done before forcing Bradenburg and friends to create methods , theories , and research of its own. Most of their work is not just about how to reduce the file size , but rather to determine the level of sound quality degradation that can be tolerated by human perception .
Brain and earsIn creating MP3 , Brandenburg analyze how the human brain and ear catching sound . The technique used successfully manipulate the ears by removing the less important part in a music file . For example , if there are two similar tones , or if the high and low notes appear simultaneously , the brain will only process one of them . So the MP3 algorithm will select a more important signal and discard sisanya.Hasilnya is capable of reducing the size of MP3 files original audio file up to 10 times smaller. For example , a song with a duration3 minutes can seize hard - disk allocation of 30 MB . The same song with MP3 format takes up only 3 MB with a minimum loss of voice quality .
Its discovery has been getting some attention in his own country , Germany . But instead he earned rave reviews during a visit to Silicon Valley to do a presentation in 1997 . There hedemonstrate knowledge of how to push the size of the WAV file without making the listener know the difference . Several parties had expressed interest to buy the project or take over ownership rights . However , Frauenhofer Institute insisted to keep all the copyright, even though they actually do not have a lot of money to keep an eye protection.
Beginning with WinampMP3 success began in 1998 , when Winamp , MP3 player a machine made by a college student named Justin Frankel and Dmitry Boldyrev , offered free of charge on the internet . In an instant, music lovers around the world are connected in a network of centers called MP3 , and each offers music that is copyrighted , for free .
Before too long , even as other programmers do not want to miss the train . They create a variety of software support for MP3 lovers ( MP3 junkies ) . Encoder , ripper , and the latest player released every week , and the growth is moving faster and faster . Search engines also make the process of finding a particular MP3 file that you want to be faster . In addition , portable players such as Rio and make MP3 iPod can be enjoyed while walking .
Currently, the MP3 is offered as a shareware program . This means that anyone interested can register at the Institute Frauenhofer and making software or MP3 files of his own . To be honest , on the matter, Bradenburg did not have much choice because this project does not have a software partner directly and do not have the budget to make the distribution and marketing chainitself .
Brandenburg stated that he was very satisfied with his work and did not take any advantage from it . He also claimed not to have a share in a company internet or any other companies that use the MP3 format . In fact , he was not interested in money at all . " I do not care about the numbers that exist in my passbook . However , I am very satisfied with what I have done , with co-workers , and what are we making together , " he told the German magazine Der Spiegel . Nevertheless , Brandenburg does not think that this system willdestroying the music industry as many have predicted ." I think it will not happen , but we did have to change the industry ... The industry must understand how to control this new digital media and the accompanying opportunities . They should concentrate on positive things rather than negative . "
declined the offerWith all the success he has achieved , various tempting offers came over , including professorial positions in the United States . Nevertheless , it remains to be modest and humble . It seems he was quite happy with the ' world kecil' her on the outskirts of Berlin .
He once told the German press that every time he surfed the internet and found the site and the latest MP3 knowing that people enjoy something he had ever made , "It gives a feeling of indescribable pleasure , " Brandenburg said one day .
