CD-R/CD-RW discs
Your CD player can playback CD-DA format audio CD-R/CD-RW discs
that have been finalised* upon completion of recording. Your CD player
may fail to playback some CD-R/CD-RW discs due to poor recording
and wide variation in quality of the CD-R/CD-RW disc.
*Finalising enables a CD-R/CD-RW disc to playback on audio players

MP3 / WMA / AAC CD Mode

The Sound 48 is able to play CD-R and CD-RW discs containing MP3 /
WMA / AAC files with a maximum of 255 files per folder. An MP3 / WMA
/ AAC CD should not contain more than a combined total of 999 files
and folders. MP3, WMA and AAC files should be created with an audio
sample rate of 44.1kHz (this is normal for files originally created from
audio CDs). Folders may be nested but to a maximum of 8 levels. Folder
and file names should ideally be less than 30 characters in length. Tags
for title / artist / album information in the files should ideally be less than
30 characters in length. Within a folder, files or folders written earlier
will generally be played before those written later and files have higher
priority than nested folders.
There are many possible variations in the formatting of CD-R and CD-RW
discs with audio files, but regular CD burning software should generally
give good results with default settings. Should problems arise, contact
the customer services of your CD burner or software manufacturer. When
creating audio CDs, please observe all legal guidelines and ensure that
the copyright of third parties is not infringed.
