Frankly,
if you are still using
audio tapes then you
really are living
in the technological
equivalent of the
Stone Age, the market
penetration of both
Mini Disc and MP3
are such that you
would be wise to put
that Walkman of yours
up in the loft next
to the Amiga
or Super Nintendo.
Prices
of both Mini Disc
recorders and MP3
players are now at
reasonable levels,
of course they could
be cheaper, especially
in the UK, but in
general they are now
affordable for the
mass majority of people.
Really the only question
is which format do
you buy into? It is
fairly confusing but
by the end of this
article you should
have a better idea
about what to do.
Mini
Disc has been around
for a while, since
1992 in fact - it
is based around Magneto-Optical
technology that allows
you to write to disc,
but it is read back
by a laser, rather
like a CD. A sort
of hybrid floppy disk/compact
disc if you will.
Obviously at the time
that was its major
advantage over the
CD, it recordability
but these day you
have CD-R and CD-RW,
so what's the point?
Size
is the major factor,
it is far more portable
than a CD - being
around 7 square centimetres
in area, and about
a third of a centimetre
deep. It means that
you can carry a fair
number of the discs
in your jacket pocket
along with the player,
something which isn't
really possible with
CD. The players themselves
are smaller than the
palm of your hand
and make even the
latest Discmen or
Walkmen look stupidly
big in comparison.
There
are a couple of problems
though, the recording
system, ATRAC, is
a form of compression
- in order to store
the same amount of
data on the disc as
is possible of CD
it goes through the
data stream and removes
bits that are inaudible
to the human ear.
Some people have been
known to be able to
tell the difference
and it is noticeable
if you play the CD
and then the MD back
to back, but for general
listening, it doesn't
effect your enjoyment
of the music. Recording
is also slow: it takes
however long your
album is to transfer
the data to the MD,
something which would
have been fine back
in 1992 but today
seems like a major
disadvantage. Also,
if you are unlucky
enough not to have
an optical output
on your stereo and
have to use Analogue
recording methods
to record, then you
can be stuck with
a big mess of extremely
long tracks. The MD
requires 2 seconds
of low sound in order
to mark a track and
these days with all
the mixing straight
into the next track,
it can get annoying.
MP3,
on the other hand
is a bit different.
Being more a compression
standard than a media
format, it fills a
gap in the market
that wasn't serviced
before.
MP3
players are really
just a big chunk of
memory attached to
earphones - in order
to actually have any
music in MP3 format
you need a PC. This
is because you need
to create a compressed
version of the CD,
something that is
currently only possible
through computer programs
called CD rippers.
This takes the data
from the CD and compresses
it extremely quickly,
certainly much faster
than recording with
MD.
The
advantages to MP3
are that it is solid
state, that means
that the player has
no moving parts and
therefore can not
break and also the
music file can not
degrade with continual
use as is the case
with audio tape or
even MD. There is
also a thriving black
market in pirated
MP3 files, so if you
are that way inclined
you never need pay
for any more albums
once you have your
MP3 player. However,
the music industry
is about to wake up
to this fact and I
expect much tighter
controls on the format
in future - maybe
a music industry developed
MP4 perhaps?
There
are numerous problems
with the format however,
the nature of the
compression means
that playback quality
can vary greatly depending
on what settings were
used during the initial
recording. The settings
you use impact on
the file size and
therefore the amount
of music you can store
on your MP3 player.
Some people can live
with the dodgy music
quality but if you
can then why not just
record out via the
headphone jack to
an audio tape?
The
average file size
for a track of "near
CD quality sound"
is 4Mb, it makes you
think though - if
I'm going to have
all my music stored
on my hard disk in
MP3 format how big
will it need to be?
I have a fairly small
music collection of
around 40 albums.
Lets say that there
is an average of 12
tracks per album,
at 4Mb a track that
works out at 4x12x40=1.92Gb
That's a lot of hard
disk space and if
your MP3 player can
only store a fraction
of that at a time,
then you're going
to have a lot of trips
to the PC to download
new tracks into the
player.
The
issue is further confused
by the arrival of
the Sony Memory Stick
format, which is a
cross between MP3
and Mini Disc. It
is solid state and
requires a PC to transfer
data like MP3, but
uses ATRAC and Media
like Mini Disc. It
is probably the format
the music industry
would like to see
win out, but it is
still too expensive
and is for the future.
It
comes down to personal
choice, do you prefer
having racks of discs
with your music collection
on them or would you
rather have it all
stored on the PC?
I'd go with Mini Disc,
cause its far easier
swapping disc than
it is to get back
to your PC when your
on a plane.
AGi.
Kiljaeden,
was kind enought to
point out a new MP3
Discman called the
Mambo X (www.mambox.com),
which plays both standard
CD's and also CD's
full of MP3 files
which removes a couple
of the complaints
I made in MP3's direction.
However, until these
become as common as
standard MP3 players
the above still stands
and in fact it removes
a couple of MP3's
benefits - its "jog
proof" nature,
the fact that the
palyers are small
and you need to own
a CD-R drive. Also
if you have visited
the site, the Discman
is really ugly and
looks like a very
cheap standard Discman
which isn't good.
