NOTES ON MP3 FILES
• An MP3 file stores audio data
compressed using MPEG1/2/2.5, the
audio layer-3 file-coding scheme.
• In this manual, CDs, CD-R discs and
CD-RW discs are all referred to as
“discs”. We refer to what are called
“folder” and “file” in PC terminology as
“album” and “track”.
Notes on playing MP3 files
• An MP3 track must be recorded on a disc
in the format compliant with ISO 9660.
Note, however, that the unit may not play
tracks in the order they were recorded.
• The maximum allowable number of tracks
and albums in a disc are as follows:
– number of tracks : 512 (depending on the
number of albums)
– number of albums : up to 255 (depending
on the number of tracks)
• The maximum allowable depth of nested
albums is 8.
• E•A•S•S memory duration is approximately
100 seconds at the longest with tracks of
128 kbps bit rate.
• It may take 30 seconds or more before the
unit can start play of MP3 tracks, depending
on the number of recorded tracks and the
complexity of the album tree.
• If a disc contains audio (CD-DA) tracks and
MP3 tracks, the unit plays only the audio
tracks.
• The unit may not play MP3 tracks recorded
using a packet writing utility.
• The unit can play MP3 tracks having a file
extension “.mp3”.
• If you play a non-MP3 track that has the
“.mp3” file extension, you may hear some
noise.
• This unit can play back MP3 files of the
following bit rates:
MPEG1/Audio layer-3: 32k-320 kbps
MPEG2/Audio layer-3: 8k-160 kbps
MPEG2.5/Audio layer-3: 8k-32 kbps
• This unit is best suited for playback of
tracks with a bit rate of 128 kbps. The
sound may be intermittent or distorted
during playback of tracks encoded with a
certain encoder or encoded with bit rate
over 128 kbps.
• The elapsed playing time may not be
displayed correctly when variable-bit-rate
(VBR) files are played.
• Sound is muted for a moment with the disc
that contains no silent portion between
songs (tracks) such as a disc with a
recording of a live performance, etc.
• When files encoded with the MP3 Pro
format are played back, their sound quality
may not be as high as they should be.
