Bitrate
This is the "sound" compression rate specijiedfor encoding. The
higher the bit rate, the higher the sound quality, but also the larger
the files.
sampling rate
This value shows how many times
per
second the data is sampled
(recorded).
For
example, music CDs use a sampling rate
of
44.1
kHz, so the sound is sampled (recorded) 44,100 times per second.
The higher the sampling rate, the higher the sound quality, but also
the larger the volume
of
data.

Files are played back
in
the order that the writing software
writes them to the disc. Therefore, the playback order may not
be what
is
expected. Verify the writing order
in
the software's
documentation. The playback order of the folders and files is
as follows.

* The folder No./jolder Name will not be displayed
if
no file is
contained
in
the folder.
Method for creating MP3IWMAlAAC files
Audio data
is
compressed using software with MP3N.JMNAAC
codecs. For details on creating MP3N.JMNAAC files, refer to
the user's manual for that software.
MP3N.JMNAAC files that can be played back by this device
have the following file extensions:
MP3: "mp3"
WMA: "wma" (ver.
2,
7 and 8 are supported)
AAC: "m4a", "aac"
There are many different versions of the AAC formal. Confirm
that the software being used conforms
to
the acceptable
formats listed above. It's possible that the format may be
unplayable even though the extension
is
valid. Playback of AAC
files encoded by iTunes version 4.8 or earlier
is
supported.
