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.
