About
MP3
An
MP3
file
is
audio
data
compressed
by
using
the
MPEG1
audio
layer-3
file-coding
scheme.
We
call
files
that
have
the
".mp3"
file
extension
"MP3
files".
The
unit
can
not
read
an
MP3
file
that
has
a
file
extension
other
than
".mp3".
About
WMA
(Window
Media
Audio)
An
WMA
file
is
a
Microsoft
audio
compression
technology.
WMA(Windows
Media
Audio)
offers
double
the
audio
compres-
sion
of
the
MP3
format.

If
you
record
MP3/WMA
files
using
the
software
which
cannot
create
a
FILE
SYSTEM,
for
example
"Direct-CD"
etc.,
it
is
impossible
to
playback
MP3/WMA
files.
We
recommend
that
you
use
"Easy-CD
Creator"
which
creates
an
ISO9660
file
sys-
tem.
5.
A
single
session
disc
requires
MP3/WMA
files
in
the
first
track.
If
there
is
no
MP3/WMA
file
in
the
1st
track,
it
cannot
playback
MP3/WMA
files.
If
you
wish
to
playback
MP3/WMA
files,
format
all
the
data
in
the
disc
or
use
a
new
one.
