Supported playback sampling rates and bit rates
MP3
WMA
AAC
This device may not play back correctly depending on sampling
rates.
In the USB mode, the playback time may not be correctly
displayed when a VBR (Variable Bit Rate) recorded file is played
back.
ID3 tags/WMA tags
This device supports ID3 tag v1 and v2, and WMA/AAC tag.
If tag data is in an MP3/WMA/AAC file, this device can display
the title (track title), artist name, and album name ID3 tag/WMA/
AAC tag data.
This device can only display single-byte alphanumeric
characters (up to 30 for ID3 tags and up to 15 for WMA tags)
and the underscore. For non-supported characters, “NO
SUPPORT” is displayed.
The tag information may not be correctly displayed, depending
on the contents.
Playing back MP3/WMA/AAC
MP3/WMA/AAC files are prepared, then written to a CD-R,
CD-RW using CD-R writing software or stored to a USB memory.
A disc can hold up to 510 files/folders (including Root Folders),
and the maximum number of folders is 255. This unit can
recognize at least 100 folders (including root folder) and 100
files per folder stored in USB memory.
Playback may not be performed if a disc or USB memory
exceeds the limitations described above.
Do not make a file’s playback time more than 1 hour.
Media supported
The media that this device can play back are CD-ROMs, CD-Rs,
and CD-RWs.
This device also can play back USB memory media.
Corresponding File Systems
This device supports discs formatted with ISO9660 Level 1 or
Level 2.
This device also can play back discs in Joliet, Romeo, etc., and
other standards that conform to ISO9660. However, sometimes
the file names, folder names, etc., are not displayed correctly.
This device also supports FAT 12/16/32 for USB memory device.
Formats supported
This device supports CD-ROM XA, Mixed Mode CD, Enhanced
CD (CD-Extra) and Multi-Session.
This device cannot correctly play back discs recorded with
Track At Once or packet writing.
Order of files
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./folder Name will not be displayed if no file is
contained in the folder.
Bit rate
This is the “sound” compression rate specified for 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.
Encoding
Converting music CDs, WAVE (AIFF) files, and other sound files into
the specified audio compression format.
Tag
Song information such as track titles, artist names, album names,
etc., written into MP3/WMA/AAC files.
Root folder
The root folder (or root directory) is found at the top of the file
system. The root folder contains all folders and files. It is created
automatically for all burned discs.
Sampling rates: 48 kHz, 44.1 kHz, 32 kHz, 24 kHz, 22.05 kHz,
16 kHz, 12 kHz, 11.025 kHz, 8 kHz
Bit rates: 32 - 320 kbps
Sampling rates: 48 kHz, 44.1 kHz, 32 kHz
Bit rates: 48 - 192 kbps
Sampling rates: 48 kHz, 44.1 kHz, 32 kHz, 24 kHz, 22.05 kHz,
16 kHz, 12 kHz, 11.025 kHz, 8 kHz
Bit rates: 16 - 320 kbps
Under the ISO9660 standard, there are some restrictions to
remember.
The maximum nested folder depth is 8 (including the root
directory). The number of characters for a folder/file name is
limited.
Valid characters for folder/file names are letters A-Z (all caps),
numbers 0-9, and ‘_’ (underscore).
