MP3 Players
Explained
Welcome to the MP3+ guide to choosing 'your ideal' player. Here
we aim to answer the most frequent questions asked.
MP3 players are available in a variety of shapes, formats
and specifications. We will endeavour to guide you through
this and help you choose 'your ideal' player.
There are three main categories of player's known as Solid
State, CD and Hard Disk based.
To get the full benefit from your music collection you are
going to want it to be portable. Up until a few years ago
your only option was a Walkman or a portable CD player. The
only problem with these 2 options was poor sound quality (walkman)
and skipping music (portable CD player) add to the fact that
they were both bulky and heavy and you can see why Digital
music formats are really taking off. Most people associate
MP3 with Napster and illegal downloads... well forget this
and look on it as a way of carrying your CD collection around
with you. Yes you can download the latest music from the Internet
but remember this is illegal and could result in prosecution
(not a good thing to happen). Grab your CD collection and
follow this beginners guide to MP3 players.... enjoy.
MP3 - MPEG-1 Layer III (or MPEG Audio
Layer III)
MP3 was introduced as a part of the official MPEG-1 standard
in 1992 and until today it is the most successful audio-standard
since WAV. Using MP3-compression PC-users are able to compress
an ordinary music-CD to one tenth of it's original size -
thus 12 hours of music could be stored on a recordable CD
that can then be played by a MP3-CD-player or an ordinary
PC. What made MP3 that popular in the end was the online peer-to-peer
program named Napster. Millions of songs were exchanged every
day via the popular program. That was solely possible by MP3,
because conventional formats such as WAV or AU were too big
in size with similar quality. MP3 also offered like WMA later
the big advantage of being streamable (This means only a selection
of the track has to be downloaded to listen to it).
Windows Media Audio - WMA
Microsoft's response to MP3, the Windows Media Audio-standard.
As it is part of the Windows Media package, Windows Media
Audio 8 was presented in early December 2000 and it is until
now the best Windows Media product.
Windows Media Audio among other things is firmly integrated
in Microsoft's Windows Media Player. Microsoft promises with
this version, almost CD-quality with around a third of the
source-file's size.
Above all WMA offers the advantage that copyright-protected
songs cannot be published any further (Digital Rights Management).
That's not the only reason why many music- and movie-corporations
meanwhile decided in favour of WMA instead of MP3. Like MP3,
WMA is almost predestined for the Internet by offering streaming
capabilities (see MP3 for details) both with WMA and WMV (Windows
Media Video).
Please note that players will refer to WMA files being supported
as either with or without DRM. This relates to Digital(Personal)
Rights Management which is an option within Windows Media
when recording/ripping. If the WMA files that are transferred
to your player are 'skipped' when trying to playback then
it is likely that this option is selected and your player
does not support it. It can be overcome by simply de-selecting
this feature and then you will have to re-record/rip your
files. This is only in reference to 'Solid State' players,
CD based players do NOT support the DRM option at all and
your files should be created with this option de-selected.
WAV
One of the first audio-standards; WAVE-files are virtually
of the same quality as data on audio-CDs and therefore offer
the best quality. At the same time these files are very large
(10 MB / min.), that's why they are unsuitable for everyday
exchange via the Internet.
How can I produce MP3 and WMA files?
To create MP3 or WMA files you will need some 'encoding or
ripping' software. There are lots of titles out there and
many of these have free downloads available. One such product
is MusicMatch and is available from www.musicmatch.com. MusicMatch
will allow you to encode you WAV files (or CD music) into
MP3. Download the software and start ripping (converting)
your music into the file format of your choice. At the moment
MP3 leads the way but WMA and others are slowly rapidly.
WMA files can be created using the Media Player Software
that often comes with your Windows Operating System. Simply
insert your CD into your CDROM drive and select the 'Copy
from CD' option in Windows Media Player. If you are connected
to the internet at this time Windows Media Player can download
the CD details to your PC and automatically names the files
ready for you to 'rip' to your hard drive. WMA files can be
smaller tham MP3 files so be sure to check the CD recording
settings on your PC to optimise your recording. Also take
note of the Copy Protection (or Digital Rights Management)
that is possible with WMA files. If you create a Copy Protected
file, you will not be able to play it back on your portable
MP3 player.
Once you have converted your files onto your hard drive you
can listen to them from your desktop, however if you want
to listen to them on the move then a portable MP3 player is
what you require.
How much music should I get on a Player?
To achieve near CD quality playback you will need to encode
MP3 files at minimum 128Kbps and WMA files at 64Kbps. At this
ratio we normally say 1MB of memory for 1 minute of music
in MP3 and around 1MB for 2 minutes in WMA, therefore a 64MB
Player will store one hours worth of CD quality MP3 files
and nearly 2 hours worth of WMA. 128Kbps is the most common
bit rate for encoding music. If you encoded your music at
64Kbps you would be able to store 2minutes of music to 1MB
or memory. The higher the bit rate the better the quality,
but the greater the file size. Obviously if you are using
one of the CD based players then you can get in excess of
700MB worth of songs and at 128Kbps that gives you around
12 hours of continuous music.
The Highs and Lows
Digital audio players have several things going in their favour
including their small size, but most people buy them for their
ability to play songs from any album in any order they choose.
Gone are the days of lugging your entire CD collection around
on trips--with digital audio players you can download your
favourite tracks from multiple albums to the player and create
your own greatest-hits album. Best of all, you can reuse the
player's memory as many times as you like, adding and removing
songs from your player as often as you like.
Most of the digital audio hardware on the market is solid
state, meaning that it has no moving parts. This makes the
units more durable and eliminates skipping (something that
owners of older portable CD-player know of only too well).
However, there are exceptions to this as there are digital
audio players that store files on hard drives, CD-R and CD-RW
media and even MiniDisc.
A stumbling block for many solid state digital audio players
is their limited storage capacity. A digital audio player
with 32MB of internal memory will store around one hour of
music encoded using MP3 audio compression and about 40% more
using the WMA format. A 64MB player offers twice the amount.
This is something to think about when buying a player especially
if you're planning on taking it on holiday. However, digital
audio files can be encoded at various bit rates, enabling
you to store more music per MB but at a cost--the lower the
bit rate, the lower the audio quality.
Filename Displays
Most digital audio players have displays that can show all
sorts of information about the track that's playing, including
the title, artist, and length. At the very least, try to find
a unit with a backlit LCD that can be read easily at night.
High-end units support detailed labels like ID3 tags (small
pieces of data--such as song title, artist, and album title--that
can be added to a digital audio file when it is created via
encoding software), while some just show the track number
and length.
Compatibility
Before buying a digital audio player, make sure it's compatible
with your computer. Most players work with PCs, but not all
of them work with Macs. Also note that just because your computer
has the required hardware to interface with the player, it
doesn't mean it will support the software that the player
needs to work. For instance, PCs with a USB port must use
Windows 95 (OSR2) or later in order to take advantage of it.
In addition, Windows NT 4.0 does not have built-in operating
system support for USB connectivity, though there are third-party
solutions available for working around this. Your computer
needs to meet (or preferably exceed) the system requirements
listed on the box to guarantee compatibility with all the
player's components. Also, just because you've got the latest
OS for your computer it doesn't automatically make all digital
audio players compatible with your hardware. Windows XP users
may have trouble with some hardware so check the technical
data and system requirements of a player before you invest.
What are the considerations when choosing 'my ideal' player?
When choosing 'your ideal' player it is worth considering
how your lifestyle may affect your choice.
High Impact Leisure (ie Running, Aerobics,
Mountain biking, Riding)
If you are going to do a lot of 'high impact' exercise then
a Solid State player is the choice for you, because they have
no moving parts and are immune to any forms of skipping caused
by movement of the player. Also the units are small and compact
and can be carried easily in pockets or via the included necklace
/ wrist strap.
General Leisure (i.e. walking, road
cycling etc)
Both Solid State & CD based players are suitable for these
pursuits, however it is advisable to look at a CD based player
with a longer anti-shock facility.
Home use (i.e. connecting to stereo
or general listening)
Although both styles of product are suitable, we would suggest
CD based products being used. This is because you will be
able to store much more music for continuous playback. You
will also be able to play your standard Audio CD's on the
12cm players.
Other examples of use and suggested product type:
On holiday, if wanting to use your player on holiday then
a CD based player is the ideal choice, as this will give you
the greatest availability of music. With up to 20 hours of
music on one CD then you should never tire of your holiday
collection. Also because the media is so cheap a few extra
CD's or backup's are very affordable.
In the car, as above.

endeavour to help you make 'your ideal' choice.
