• Supported playback sampling rates and bit rates
Sampling rates: 8 kHz - 44.1 kHz, bit rates: 8 - 320 kbps
Note that for sampling rates such as 11,025 kHz, this
device’s frame display (Page 12) may not display
correctly.
• ID3 tags
This device supports ID3 tag v1.
If ID3 tag data is in an MP3 file, this device can display
the title (track title), artist name, and album name ID3 tag
data.
This device can only display single-byte alphanumeric
characters and the underscore. For non-supported
characters, “NO SUPPORT” is displayed.
• Producing MP3 discs
MP3 files are prepared, then written to a CD-R or CD-RW
using CD-R writing software. A disc can hold up to 512
files/folders (including Root Folders).
• Media supported
The media that this device can play back are CD-ROMs,
CD-Rs, and CD-RWs.
• Corresponding File Systems
This device supports discs formatted with ISO9660 Level
1 or Level 2.
Under the ISO9660 standard,
there are some restrictions to remember.
The maximum nested folder depth is 8 (including the
root directory). File/folder names are limited to 31
characters (including the extension).
Valid characters for folder/file names are letters A-Z (all
caps), numbers 0-9, and ‘_’ (underscore).
This device also can play back discs in Joliet, and other
standards that conform to ISO9660. However,
sometimes the file names, folder names, etc. are not
displayed correctly.
• Formats supported
This device supports CD-ROM XA, Mixed Mode CD,
Enhanced CD (CD-Extra) and Multi-Session.
This device can not correctly play back discs recorded
with Track At Once or packet writing.
• Order of tracks
Track playback is based on the pathname order used for
the files when they were written to the CD.
• When CD audio and MP3 files are both present on a
disk, playback starts from Folder No. 1.
Also, the track display for CD audio data playback is the
track numbers recorded on the disc.
Terminology
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 level 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.
ID3 tag
Song information such as track titles, artist names,
album names, etc., written into MP3 files.
