INTRODUCTION

Two years ago, MP3 was just another audio compression format. Today, it's a Net phenomenon that's at the center of an enormous controversy. That's because MP3 makes it possible for people with an Internet connection to bypass record stores (and cashiers) and download CD-quality music by their favorite artists--for free. MP3 is great for music lovers and cheapskates, who can download funky tunes to their hearts' content without spending a dime; however, it's a nightmare for musicians and record companies, who can only watch helplessly as their profits drop into a digital black hole.
DEFINITION
MP3 is short for MPEG-1 Layer 3 (Moving Pictures Expert Group), a format for storing digital audio. It uses an advanced type of audio compression which reduces the filesize with little reduction in quality. MP3 is used particularly for music distribution over the Internet, but is also use for other purposes such as real-time digital audio transmissions over ISDN (used by reporters). MPEG-1 has been around since 1992, but during he last few years (1998/99) it has started to get widespread attention from regular media and ordinary users.
An MP3 file (or simply "an MP3") is a file that contains MP3-compressed sound data. It is played using an MP3 player. You can recognize MP3 files by their file-extension (the end of the filename), which is ".mp3".
AUTHORS
MP3 was invented by Fraunhofer IIS – leading organization of applied research in Germany In a joint cooperation with the University of Erlangen (Prof. Dieter Seitzer) under the sponsorship of the Motion Picture Experts Group (MPEG) and formalized by the International Organization for Standardization (ISO).
SOUND QUALITY
The original 50 MB wave file (about 5 minutes of CD quality audio)
MP3-compressed will end up as an MP3 file using only about 5 megabytes of space with little or no audible loss in quality. The size depends on the length of the song and the bitrate (quality). The data is automatically decompressed while the MP3 is being played.
How is it possible to do this you ask? Well, I won't get into the technical details, but basically the MP3 encoder removes the parts of the sound not audible to the human ear. This means that MP3 is a 'lossy' type of compression (comparable to JPEG in the graphics area). This means that what comes out from your CD or Wave file is NOT the same t...

CD Extracting Software
CD extracting software (normally called a "grabber" or "ripper") is a programme that can extract tracks from an audio CD, making a copy of them on hard disk in wave format. These wave files are the starting point for creating Mp3 files, which are much smaller in size; in fact many rippers feature an MP3 converter and can obtain an MP3 file from an audio CD, going through the wave format which is then automatically deleted in order to free up space.
Utility Programmes
This is software that carries out accessory operations, with no direct effect, but with the result of simplifying other operations.
Typical examples are: WinZIP (to manage compressed archives), Cool Edit Pro (to manage wave files whilst changing their characteristics or applying sound effects) and Mp3Wolf (useful in the search for MP3 files on the net).
CONCLUSION
As you can see it is Mp3 format can be very useful for end users. It is allow you to store many files of your favorite music on your hard disk and listen them any time you like using many good features of MP3 player .

    Technically chivalry is defined as the moral code of knights in medieval times i.e.: dignity, courtesy, bravery, generosity, and gallantry.  This was the manner of respect in which women were to be treated, and a knight was to uphold the code always.  One can imagine courtly ladies strolling through the court in fine gowns, and having a chivalrous knight lay his cloak over a muddy patch so the ladies shan't muss their shoes. These days should some kind man stand for an extra second at a door to keep it open for an approaching woman, she may be amazed at this display of courtesy.

    813 Words  | 2 Pages

    Cemeteries are a place for people to bury their loved ones for them to rest to be visible and visitable later. People chose the location of their burial sites very carefully. Some people chose their cemetery because of its proximity to something meaningful (childhood home, family memory, current location) or to honor something greater (soldiers being buried at Arlington National Cemetery). Although the cemetery itself may have meaning, the gravesite within the cemetery itself can also be very important. The tombstone can be a sign of class, wealth, or nationality with the location and design of the tombstone. For my fieldwork was centered around the cemetery which my grandfather was buried at, and it shows the progression of a community of people and tells some ways to

  • Online Music Distribution In A Post-Napster World

    994 Words  | 2 Pages

    Before the 1990’s, if people want to listen to music, they just visit a music store and pick up a CD and then put it into a stereo equipment. However, the development of MP3 file format gradually changed the way people listen to music. This format lets everyone download music easily and it can be converted to CD as well. But, there is still a problem: searching MP3 files on the internet is maddening and people seldom can find the music they want. Therefore, the birth of Napster solved this problem, creating a virtual music community in which music fans could use the Web as a “swap meet” for music files. More importantly, Napster is easy to use and it’s free, which expands the range of audience in age. Bandwidth also contributed to Napster’s success. The greater the bandwidth, the faster the file can be transferred. So, Napster really changed the way people listen to music, discover music and interact with music.

    BD and DVD both have pits and bumps. The difference between the two is that the BD pits and bumps are smaller and packed closer together. A blue laser is used to read the BD. The BD has spiral tracks running from the center of the disc out to the edges. The information is stored in these tracks in the form of audio and video. The blue laser used to read this information has a wavelength of approximately 405 nanometers and must be much more accurate than that of a DVD as the pits and bumps are smaller and closer together.

  • The Impact of Digital Signal Processing

    Most of the applications in terms of speech and audio compression may seem obvious at first, but what most do not realize is the scale at which it is used. Some of the more common examples include: telephone communications, compact disc players in the form of digital audio coding, stereo sound systems, speech recognition and playback, noise reduction/filtering after voice recognition and speech synthesis [1]. The uses of DSP for speech and audio compression is certainly not limited to these examples, but just these alone are examples that the general public use through various devices on a daily basis often without realizing the function of the systems and processes that go into their operation.

    ...P, 2005, p 23) Around 2005 cell phones and PDAs were referred to as Swiss army knives of gadgets due to the fact they had many functions in one device. All the big phone companies at the time were premiering phones with more mp3 storage than mp3 player, essentially foreshadowing the future. (Dempsey, P, 2005, pg. 23)An average smart phone in the year 2014 can hold around 8-16 gigabytes of data, and if storage is allotted correctly, the phone can hold thousands of mp3s. Any mp3 player trying to have a foothold in the consumer market cannot compete with a device that is an essential part of an average person’s daily life, and a music player. “Smartphones with increasingly high-quality audio and video capabilities have become popular and therefore hamper demand for products in the Audio and Video Equipment Manufacturing industry.” (Krabeepetcharat, T. 2013. p. 8)
