MP3 encoding technology

April 22nd, 2009

The mp3 is a completely heaven sent gift for anyone who enjoys and appreciates tremendous music. Not only does it offer users total convenience of purchasing and then downloading 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 begin to think of to name. These players allow you to download hundreds and in many cases thousands of mp3’s to carry along with you anywhere.

I make mp3 CD’s containing up to 120 of my favorite songs for my listening satisfaction in my car. But how can so numerous audio files get stored on my 800MB (Megabyte) CD?

Simple! It’s all to do with the way mp3’s are made. mp3 Encoders and mp3 converters are the software that creates mp3s by using an p3 compression and decompression algorithm.

For instance, an average 3 minute WAV file can be as big as 15MB. Using mp3 encoders and mp3 converters, a fat WAV file can be cut down to a very muc more manageable and more portable mp3 file of about 3MB.

mp3 actually stands for MPEG Audio Layer 3.

At this layer 3, the principles of psychoacoustics are employed to find and remove all unnecessary sound data, to leave behind nothing but the crucial audio data. All unnecessary sound data, by which I mean all of the sounds that we humans don’t hear at any rate, is effectively removed, leaving behind the much smaller mp3 file. Most mortals 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 entertainment albums, can be pared down to an even smaller file based on this principle.

Compression occurs subsequent to the removal of the extraneous data, when only the vital data is left behind.

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 greater the bit rate, the higher the sound quality. Conversely, the lower the bit rate ratio, the poorer the quality.

192 Kb/s is the most popular bit rate utilized in peer-to-peer networks.

For the most part, mp3 converters and encoders today use variable bit rates, which allows for hugely superior quality audio, because the bit rate conforms to the dynamics of the audio frames being stored which in turn keeps far more of the vital music data.

There are dozens of mp3 compressor and encoder software programs available both online and at stores.
