MP3 MODE

MP3 mode
On the Woodstock DAB52 you can also
play CD-Rs containing MP3 music files.
MP3 is a process developed by the
Fraunhofer Institute for compressing CD
audio data. Compression allows data to
be reduced to around 10% of their orig-
inal size without a noticeable loss in
quality (at a bit rate of 128 Kbit/s). If a
lower bit rate is used to convert CD au-
dio data to MP3, you can create small-
er files but there will be a loss in quality.

Preparing the MP3 CD

The various combinations of CD burn-
ers, CD burning software and CD blanks
may lead to problems arising with the
ability to play certain CDs. If problems
occur with your own burned CDs, you
should try another brand of CD blank or
choose another blank colour. Best re-
sults are achieved with CD blanks that
provide 74 minutes of playing time.
The format of the CD must be ISO 9660
Level 1 or Level 2. Other formats can-
not be played reliably.
Avoid multi-sessions. If you write more
than one session to the CD, only the
first session will be detected.
In order to avoid overly long access
times, you should not create more than
20 directories on any MP3-CD that you
want to play on the Woodstock DAB52
(though a maximum of 254 directories
are technically possible). These direc-
tories can be individually selected on the
Woodstock DAB52.
66
Each directory can contain up to 254
tracks and subdirectories, which can
also be selected. A maximum of 8 lev-
els of directories are allowed.

Since using some burner software can
lead to inconsistencies in the way items
are numbered, you should ensure that
the root directory D01 either contains
only subdirectories containing tracks
(Fig. 1) or only tracks (Fig. 2).
