MP3, WMA and AAC
files
•
MP3 is short for MPEG Audio Layer 3 and
refers to an audio compression technology
standard.
•
WMA is short for Windows Media™
Audio and refers to an audio compression
technology that is developed by Microsoft
Corporation. WMA data can be encoded by
using Windows Media Player.
•
AAC is short for Advanced Audio Coding
and refers to an audio compression tech-
nology standard.
•
With some applications used to encode
WMA files, this unit may not operate cor-
rectly.
•
With some applications used to encode
WMA files, album names and other text
information may not be correctly displayed.
•
This unit allows playback of MP3/WMA/AAC
files on CD-ROM, CD-R, CD-RW discs and
USB portable audio player/USB memory.
Disc recordings compatible with level 1 and
level 2 of ISO9660 and with the Romeo and
Joliet file system can be played back.
•
MP3/WMA/AAC files are not compatible
with packet write data transfer.
•
The maximum number of characters which
can be displayed for a file name, including
the extension (.mp3, .wma, .m4a), is 24,
from the first character.
• The maximum number of characters which
can be displayed for a folder name is 24.
• In case of files recorded according to the
Romeo file system, only the first 24 char-
acters can be displayed.
• The folder selection sequence for playback
and other operations becomes the writing
sequence used by the writing software.
For this reason, the expected sequence at
the time of playback may not coincide with
the actual playback sequence. However,
there also is some writing software which
permits setting of the playback order.
IMPORTANT
• When naming an MP3/WMA/
AAC file, add the correspond-
ing filename extension (.mp3,
.wma, .m4a).
• This unit plays back files with
the filename extension (.mp3,
.wma, .m4a) as an MP3/WMA/
AAC file. To prevent noise and
malfunctions, do not use these
extensions for files other than
MP3/WMA/AAC files.
MP3 additional
information

1.0, 1.1, 2.2, 2.3 and 2.4 formats for display
of album (disc title), track (track title), artist

• The sound quality of MP3 files generally
becomes better with an increased bit
rates. This unit can play recordings with
bit rates from 8 kbps to 320 kbps, but
in order to be able to enjoy sound of a
certain quality, we recommend using only
discs recorded with a bit rate of at least
128 kbps.
