<\/p>\nMP3 is a storage format for compressing audio data. It occupies about 1\/10 of the storage space of a corresponding CD or wave audio file.<\/p>\n
<\/p>\n
This means that one minute has a storage requirement of approximately one megabyte.<\/p>\n
– For this reason, the files are very popular for distribution on the Internet.<\/p>\n
It takes an average of ten minutes to load a song from the Internet in near CD quality.<\/p>\n

– So-called file sharing programs are freely available on the Internet and are used<\/p>\n
to exchange music between individuals. The best known of these exchanges is “Napster,” which has been in the spotlight for months due to various legal disputes with record companies.<\/p>\n

The abbreviation for “Moving Pictures Experts Group” is. So the full name is “Moving Pictures Experts Group 1 Audio Layer 3”.<\/p>\n
– MPEG is a format for compressing videos, so the real purpose of MP3 was to deliver the sound to the videos before it passed “on its own” and gained popularity.<\/p>\n
– According to the IT magazine CHIP (10\/2000 edition), 73% of young people in Germany use MP3 files. The difference will hardly be noticeable.<\/p>\n
– The predecessors of Layer 3 were Layers 1 and 2, whose data compression was not yet sufficient for distribution on the Internet.<\/p>\n
– Layers 1-3 were developed by the Fraunhofer Institute in Darmstadt in Germany.<\/p>\n
The department of the IIS (Institute of Integrated Circuits) has been working on audio compression methods since 1987 with the original goal of transmitting music over the telephone, which has been achieved in the broadest sense with the Internet.<\/p>\n
– MP3 is a so-called “headerless file format”. The files do not have<\/p>\n
Headings in the traditional sense, but they have multiple headings for the respective subareas.<\/p>\n
MP3 AND INTERNET<\/p>\n
Due to the low data capacity, the MP3 format has become more and more popular for downloading on the Internet in recent years. There are countless websites that offer MP3 files for free. However, file-sharing networks like Napster are much more popular. These are based on the following principle: each user loads the program from the Internet, logs in and can “exchange” music with other users. The program registers the user in one of the numerous servers each time the program is started and the files can be downloaded from any other user on this server by entering the title and artist. You get a large number of results for almost every song. After choosing the best connection, upload the file to your computer.<\/p>\n
Unfortunately, this simplicity is too good to be true. Record companies have now noticed that money is flowing through their fingers and they intervene by suing Napster for copyright infringement. The process takes more than half a year. In March of this year, Napster had to agree to filter the download of copyrighted titles. But as Napster goes down, tons of similar shows emerge, making it difficult for record companies to stop the illegal music trade as new tools hit the market almost every day.<\/p>\n
The development of music downloads from websites is similar: most providers disappear after a short time, but a new page is placed on the net somewhere. You can always find the song you are looking for using a search engine.<\/p>\n
However, record companies have already developed that only use the Internet market. It is precisely with these companies that young talents have a great opportunity to become famous. The songs can be loaded onto the home computer for around 15 ATS each.<\/p>\n
CODING<\/p>\n
The first step in encoding by the user is to specify a bit rate. This indicates the quality and at the same time the storage requirement of an MP3 file.<\/p>\n
COMPRESSION RATES<\/p>\n
With most recording programs, the quality of an MP3 file can be freely selected before recording begins. According to the Fraunhofer Institute, the CD quality of an MP3 file is a bit rate of 112 to 128 kbit per second, other measurements put CD quality at up to 160 kbit per second. However, the most used and sufficient for most listeners is 128 kbit.<\/p>\n
In comparison, a corresponding CD quality for Layer 1 is 384 kbit \/ s and 256 kbit \/ s for Layer 2. A wave file works with a 1.4 Mbit \/ s bit rate and therefore works with roughly the same space requirements. as a CD audio track (CDA).<\/p>\n","protected":false},"excerpt":{"rendered":"
