Control systems COMAND audio CD/audio DVD/MP3 Multisession CDs For multisession CDs, the first session type of the CD determines how COMAND will process the CD. For example, if the first session type is according to the audio CD standard and the second session type is according to the data CD standard containing MP3 tracks, COMAND will treat the CD as a conventional audio CD. This means that it is only possible to access the audio CD tracks. Access to the MP3 tracks is not possible. Similarly, if the first session type is according to the data CD standard containing MP3 tracks and the second session type is according to the audio CD standard, COMAND will treat the CD as a data CD. This means that it is only possible to access the MP3 tracks. Access to the audio CD tracks is not possible. File structure on a disc When you create an MP3 disc, the MP3 tracks can be organized in folders. A folder can also contain other folders. A disc can contain a maximum of 255 folders. Each folder can contain a maximum of 255 tracks and 255 folders. A disc can contain a maximum of 4000 tracks. Usually this number will not be reached because each minute of an MP3 track requires approximately 1 MB of storage space. Track and folder names When you create an MP3 disc, you can assign names to the MP3 tracks and folders. COMAND uses these names for the corresponding display in MP3 mode. Empty folders or folders which contain data other than MP3 tracks are not displayed by COMAND. If MP3 files are saved in the root directory itself (uppermost directory on storage medium), the root directory will also be treated as a folder. COMAND will then show the name of the root directory as the folder name. You must observe the following when assigning track names: Track names must have at least one character. Track names must have the extension "mp3". There must be a period between the track name and the extension. Example of a correct track name: Track1.mp3 COMAND is unable to recognize an MP3 track if: there is no period between the track title and the extension there is no extension i COMAND does not support ID3 tags. 113
