(Variable Bit Rate (VBR) compatible)
MP3 (MPEG Audio Layer 3), WMA
(Windows Media Audio) and AAC
(Advanced Audio Coding) are audio com-
pression standards.
This system can play MP3/WMA/AAC files
on CD-R, CD-RW discs and USB memory.
When naming an MP3/WMA/AAC file, add
an appropriate file extension (.mp3/.wma/
.m4a).
This system plays back files with .mp3/
.wma/.m4a file extensions as MP3/WMA/
AAC files respectively. To prevent noise
and playback errors, use the appropriate
file extension.
WMA/AAC files can contain a WMA/AAC
tag that is used in the same way as an ID3
tag. WMA/AAC tags carry information
such as track title and artist name.
The emphasis function is available only
when playing MP3/WMA files recorded at
32, 44.1 and 48 kHz.
This system can play back AAC files
encoded by iTunes.
The MP3/WMA player does not play back
MP3/WMA files from discs recorded using
packet write data transfer (UDF format).
Discs should be recorded using “pre-mas-
tering” software rather than packet-write
software.
MP3i (MP3 interactive) and MP3PRO for-
mats are not compatible with the audio
player.
The player is compatible with VBR (Vari-
able Bit Rate).
When playing back files recorded as VBR
(Variable Bit Rate) files, the play time will
not be correctly displayed if the fast for-
ward or reverse operations are used.
It is not possible to check folders that do
not include MP3/WMA/AAC files.
The order changes depending on the per-
sonal computer and MP3/WMA/AAC
encoding software you use.
