About MP3
and WMA
MP3 is the acronym for Moving Picture Experts Group (MPEG) Audio Layer 3, a
type of audio data compression technology developed by a group of companies
working together as a subgroup of the International Standards Organization (ISO).
The term went on to become an official standard in 1992 as a part of the MPEG-1
standard. The company primarily associated with MP3 is Fraunhofer Gesellschaft
(FhG) in Germany, who owns key patents to the technology.
The MP3 format can significantly reduce a digital audio file's size by as much as
one-twelfth of the original, with virtually no loss in quality. It is an efficient way to
store high-quality music or other audio content on your computer. MP3 digital
audio files have the file extension .MP3.
WMA is a similar compressed audio format. Developed by Microsoft, it is touted to
offer audio quality similar to the MP3 format but at half the file size. WMA files
have the file extension .WMA.
Take note that WMA files may be protected. They may be created with a digital
protection system, or may require a fee before usage. Creative TravelSound MP3
can only play back unprotected WMA files. Protected files need to be 'unlocked' on
your computer before being transferred to the Creative TravelSound MP3 for
playback. Do note that for WMA files, they can be created with digital protection or
attached business rules such as requiring monetary payment before they can be
played. These are known as protected WMA files.
The choice between MP3 and WMA file format depends largely on your preference.
You can sample these files by downloading them from various Internet sites. You
can also legally produce them from original audio CDs, provided they are for
personal use only.
It is illegal to encode
MP3 or WMA files for
trade or sale unless you
have the express and
explicit permission of
the copyright holder(s).
