Lisa Compact 28
7.2 Prepare playback from card
Before you can start playback from the card, you need to place a playlist and the tracks that it uses
onto the SD Card, according to the Requirements for playlists on the card and to the Requirements for
audio tracks on the card.
7.3 Start playback from the card
When the files on the card are in place (see Prepare playback from card), there are several options to
make the Lisa play a playlist from the card:
·
Using a task (see Task scheduling)
·
Using a command, for example via Lisa Configuration Tool or the monitoring server (see Sending
commands using the monitoring server). See Commands for a complete overview.
After a couple of seconds, the Lisa will start playing and you will hear audio coming out of your audio
installation.
7.4 Requirements for audio tracks on the card
The following rules apply for storing audio tracks on the card:
·
It is recommended that you format your card in FAT32, because a FAT16 formatted card can have
only 512 files in the root folder. When the filenames (without extension) are longer than 8 characters,
the maximum number of files for FAT16-formatted cards decreases proportionally. The Streamit Card
and Scheduler Toolkit can also be used to start formatting the card with the proper parameters.
·
All files must be in the root and not arranged into folder(s)
·
The audio file name length (including the file extension) must not exceed 128 characters characters
(due to the Requirements for playlists on the card)
·
The ASCII printable characters (see Wikipedia ASCII printable characters) are supported, except the
characters that are excluded for FAT32 filenames: " * / : < > ? \\ |
The Lisa supports all audio file formats as described in Supported audio formats and streams.
7.5 Requirements for playlists on the card
Playlists on the SD card should be made following these rules (an example can be found below):
·
You can have a maximum of 50 playlists with the ‘pls’ extension.
·
The playlists “must” be named incrementally from 1 to 50. You are not obliged to have 50 playlists, but
in case you want to have e.g. two, they must be named ‘1.pls’ and ‘2.pls’ (not 2.pls and 4.pls for
example, this would result in no playlists being recognized by the Lisa at all).
·
Playlists must follow the PLS standard (Wikipedia PLS format description), and specifically
