Understanding MP3
The name comes from MPEG (pronounced EM-peg), which
stands for the Motion Picture Experts Group. MPEG develops standards for audio
and video compression. MP3 is actually MPEG Audio Layer 3.
MP3 competes with
another audio file format called WAV. The key difference is that MP3 files are
much smaller than WAV files. An MP3 file can store a minute of sound per
megabyte, while a WAV file needs 11 or 12 megabytes to hold the same amount.
How does MP3 achieve this compression. Instead, they sample the performance and
store a discrete code for each sampled note. A CD or WAV file may sample a song
44,000 times a second, creating a huge mass of information.
By stripping out sounds
most people can’t hear, MP3 significantly reduces the information stored. For
instance, most people can’t hear notes above a frequency of 16 kHz, so it
eliminates them from the mix. Similarly, it eliminates quiet sounds masked by
noise at the same frequency. The result is a file that sounds very similar to a
CD, but which is much smaller. An MP3 file can contain spoken word
performances, such as radio shows or audio books, as well as music. It can
provide information about it self in a coded block called a tag. The tag may include
the performer’s name, a graphic such as an album cover, the song’s lyrics, the
musical genre, and a URL for more details.

SUMMARY
This information to tell more details about
understanding MP3, MP3 is MPEG Audio Layer 3 that develops standards for audio and video
compression. MP3 has smaller files than WAV files because they sample the
performance and store a discrete code for each sampled note. MP3 significantly
reduces the information stored by stripping out sounds but MP3 file can contain
spoken word performances, such as radio shows or audio books, as well as music.
It can provide information about it self in a coded block called a tag. And so,
that conclusion is MP3 is MPEG Audio Layer 3 that develops standards for audio and video
compression that has smaller files than WAV.
