About MP3/WMA/AAC
CAUTION
Except for private use, duplicating audio data (including MP3/
WMA/AAC data) or distributing, transferring, or copying it,
whether for free or for a fee, without permission of the copyright
holder is strictly prohibited by the Copyright Act and by
international treaty.
What is MP3?
MP3, whose official name is “MPEG-1 Audio Layer 3,” is a compression
standard prescribed by the ISO, the International Standardization
Organization and MPEG which is a joint activity institution of the IEC.
MP3 files contain compressed audio data. MP3 encoding is capable of
compressing audio data at extremely high ratios, reducing the size of
music files to as much as one-tenth their original size. This is achieved
while still maintaining near CD quality. The MP3 format realizes such
high compression ratios by eliminating the sounds that are either
inaudible to the human ear or masked by other sounds.
What is WMA?
WMA, or “Windows Media™ Audio,” is compressed audio data.
WMA is similar to MP3 audio data and can achieve CD quality sound
with small file sizes.
What is AAC?
AAC is the abbreviation for “Advanced Audio Coding”, and is a basic
format of audio compression used by MPEG2 or MPEG4.
Method for creating MP3/WMA/AAC files
Audio data is compressed using software with MP3/WMA/AAC codecs.
For details on creating MP3/WMA/AAC files, refer to the user’s manual
for that software.
MP3/WMA/AAC files that are playable on this device have the file
extensions “mp3”/“wma”/“m4a”. Files with no extension cannot be
played back (WMA ver. 7, 8 and 9 are supported). Protected files are not
supported, neither are raw AAC files (using the “.aac” extension).
There are many different versions of the AAC format. 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 is supported.
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.
If information contains characters other than ID3 tag information, the
audio file may not be played back.
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 most 20 Banks (1, 000 files per
Bank) stored in USB Memory/Portable audio player.
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.
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).
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.
