MP3 Encoding Technology
The MP3 is a complete godsend
for anyone who enjoys and appreciates good music. Not only
does it afford users the convenience of purchasing music online
and ripping from purchased CDs, it also provides the utmost
ease in portability. There are more MP3 players on the market
than I can name. These players allow you to download hundreds
and in some cases thousands of MP3’s to take along with you
anywhere. I create MP3 CD’s containing up to 120 of my favorite
songs for my listening pleasure in my car. But how can so
many audio files get stored on my 800MB (Megabyte) CD?
MP3 Encoders and MP3 converters are the software that creates
MP3s by using an MP3 compression and decompression algorithm.
For example, an average 3 minute WAV file can be as large
as 15MB. Using MP3 encoders and MP3 converters, a large WAV
file can be cut down to a much smaller and more portable MP3
file of about 3MB.
MP3 stands for MPEG Audio Layer 3. At layer 3, psychoacoustics
principles are used to find and remove all unnecessary sound
data, leaving behind only the crucial audio data. By unnecessary
sound data I mean all of the stuff that we humans don’t hear
anyway. Most people can’t hear sounds above 16 kHz so why
would you want it hogging your disk or hard drive space? Non-music
audio such as speeches, sermons, audio books and comedy albums,
can be reduced even less based on this.
Compression occurs after the essential data has been separated
from the redundant data. At this stage, the same amount of
data can be stored using fewer bits and less space. The bit
rate is the ratio of the number of bits transferred between
two devices per second. The higher the bit rate, the higher
the sound quality. The lower the bit rate ratio, the lower
the sound quality. 192 Kb/s is the most popular bit rate used
in peer-to-peer networks. For the most part, MP3 converters
and encoders today use variable bit rates. This allows for
much better quality audio because the bit rate conforms to
the dynamics of the audio frames being stored which in turn
keeps more of the important music data.
There are dozens of MP3 compressor and encoder software programs
available online and at stores. Some of the main encoding
engines are: LAME, Blade Enc, Fraunhofer Encoders and Xing.
Deciding which MP3 encoding engine technology is right for
you depends on your individual needs and preferences. Blaze
Media Pro is an excellent option if you're looking for a powerful,
yet easy to use, all-in-one multimedia solution.
