¡
High bit rate and high sampling frequency are recom-
mended for high quality sounds.
¡
Selecting VBR (Variable Bit Rate) is not recommended
because playing time is not displayed properly and sound
may be skipped.
¡
The playback sound quality differs depending on the
encoding circumstances. For details, refer to the user
manual of your own encoding software and writing soft-
ware.
¡
Be sure to put an extension compatible with the format.
¡
It is recommended to set the bit rate to “128 kbps or
more” and “fixed”.
Recording MP3 Files on a CD-Media
Compressed audio file writing
¡
Do not save an audio file (CD-DA file) and a com-
pressed audio file on the same disc. Failure to
observe this may result in difficulty in playing.
¡
If compressed audio files formatted with two or more
types are saved on the same disc, each format shall
have a different folder.
¡
Do not write files other than compressed audio files.
¡
Playability may depend on the combination of writing
software and disc writer to be used.
¡
This unit does not support the play list function.
¡
Write files in a disc-at-once manner unless otherwise
needed.
¡
You can shorten the duration between data read and
playback by decreasing the quantity of files or folders,
or the depth of the hierarchy.
Supported file systems
ISO 9660 Level 1/Level 2, Apple Extension to ISO 9660,
Joliet, Romeo
Note
: Apple HFS, UDF 1.50, Mix CD and CD Extra are
not supported.
Maximum number of files/folders
¡
Maximum depth of trees: 8
¡
Maximum number of files: 999
¡
Maximum number of files in one folder: 999
¡
Maximum number of folders:
256 (Root folder is included.)
Notes
:
¡
You can shorten the duration between data read and
playback by decreasing the quantity of files or folders,
or the depth of the hierar
chy.
¡
This unit counts the number of folders irrespective of
the presence or absence of an MP3 file.
¡
If the selected folder does not contain any MP3 files,
the nearest MP3 files in the order of playback will be
played.
¡
Playback order may be different from other MP3 play-
ers even if the same disc is used.
¡
“ROOT” appears when displaying the root folder name.
