Free MP3: Know all about it and get it free!
What is mp3?
Mp3 is a name of a file extension specifically the type of file for MPEG, audio layer 3.
Coding schemes includes layer 1, layer 2, and layer 3. Layer 3 is responsible for the compression of audio signals. It uses perceptual audio coding and psychoacoustic compression to remove the redundant and irrelevant parts of a sound signal like the sound the human ear does not hear.
It increases frequency resolution 18 times higher than that of layer 2 because MDCT (Modified Discrete Cosine Transform) that implements a filter bank. It is also capable of compressing the original sound data from a CD with a bit rate of 1411.2 kilobits per one second of stereo music by a factor of 12 down to 112-128kbps without sacrificing sound quality.
What are the Qualities of an Mp3 audio?
Mp3 is a lousy format providing a number of different options for its bit rate. Bit rate is the number of bits of encoded data representing each second of audio.
The quality of Mp3 files is dependent upon the quality of the encoder and the difficulty in encoding signals. Mp3 files encoded with lower bit rate generally playback at lower quality. Too low bit rate affects compression artifacts thus sounds that were not present during the encoding may appear in the reproduction.
Mp3 with a compression ratio of approximately 11:1 can achieve sound quality superior to FM radio and cassette tape due to limitation of bandwidth, SNR and other analog media.
How does Mp3 go public?
ISO MPEG Audio committee members developed reference simulation software written in C language known as ISO 11172-5 to produce bit complaint MPEG Audio files (Layer 1, Layer2, and Layer 3). It was able to demonstrate the first real time hardware decoding (DSP based) of compressed audio.
13enc was the first software Mp3 encoder released on July 7, 1994 by Fraunhofer Society. The files had been named .bit until the team have chosen the file extension.mp3 on July 14, 1995.
Many people were able to encode and playback Mp3 files on their PCs due to the release of Winplay3-the first real-time software Mp3 player on September 9, 1995.
Mp3 files are small so they can be easily transferred across the internet. Small hard drives ranging 500MB during its invention can store music on the computer. It gives a breakthrough in listening music using computers.
Mp3 files during the first half of 1995 became popular in the internet due to and interchangeable with the successes of companies and software packages. Nullsoft Winamp was released in 1997 while mpg123 and Napster in 1999 gives a breakthrough for the user’s easy playback, create, share and collect Mp3s.
Widespread of Mp3 files on the internet created a controversy that arises regarding peer-to-peer file sharing of Mp3 files. High compression enables sharing of files that are too large and cumbersome to share. People should also be aware of the intellectual property rights so that filing of lawsuit can be prevented.
You can choose from the following architecture free Mp3 players. I-tunes for the Macintosh and PC, Winamp for Windows 95/98 or NT or XMMS if you are using UNIX are great tools.
