Different types
of file formats can allow you to decrease the
size of your media files. The listening quality
of WMA and AAC files are very good yet they
take up less storage capacity than MP3 files.
For further information about different file
types then please read the next section below.
File Types
MP3 players play a range of different file
formats. You will need to check the compatibility
of your player with your current digital music
collection and with the type of digital files
that you intend to download from authorised
websites.
The most popular
sound file formats are:
MP3
- MPEG-1 Audio Layer is a near-CD quality file
format
WMA
- Windows Media Audio (used by Microsoft's Windows
Media Player)
WAV
- Windows Audio-Video Format (used by Microsoft's
Windows Media Player)
AAC
- Advanced Audio Codec (used by iTunes)
ATRAC
- Adaptive Transform Acoustic Coding (used by
Sony products)
AIFF
- Audio Interchange File Format (used by Apple
Macs)
There is very little
difference between each of these file formats.
They all make the files smaller by removing
the parts of the music that you cannot hear
and by compressing the files.
Rivalry between MP3 manufacturers has led to
players not being able to play all file formats.
Apple iPods will not play Microsoft's WMA format,
whilst Creative Labs' Zen models will not play
the AAC format closely associated with Apple.
If you plan on buying all your music from
Apple's iTunes then you will be mostly limited
to buying an iPod. If you decide to use the
WMA format then you have a broader choice of
players.
If you want to play video, then you will have
to consider which video file formats you can
view. Apple's iPod video will only let you watch
their Quick Time format, whereas other models
are more flexible, allowing playback of the
common DivX and MPEG4 formats.
