File Names
The 8TraXX uses the
number part of the file
name to identify the
sound number.
The media must be
formatted in the
8TraXX, but files may
be copied using a PC
with a Compact Flash
adapter. Care should be
taken to avoid long
filenames, or other
features not supported
by the FAT16 file
system.
Do not delete files and
then copy additional
ones. This will fragment
the media. To delete
files, copy all of the
required files to the
PC’s hard drive, format
the Compact Flash card
in the 8TraXX, and then
recopy the desired files.
File names are represented in simple DOS 8.3 format – in other words, an eight
character name, a period, and then a three character extension. The following is
an example of valid file names for the 8TraXX:
SND00001.MP3 (sound number one - interruptible)
SND00020.MP3 (sound number twenty - interruptible)
SND01005.MP3 (sound number five – uninterruptible)
The name is made up of eight characters beginning with SND followed by the
number of the file (5 digits from 00001 to 00511, or 01001 to 01511), and then
followed by the .MP3 extension.
Interruptible versus Uninterruptible Operation
The number part of the file name identifies the sound number. Sound numbers
can range from 1 to 511, and 1001 to 1511. The two ranges provide a way for
the 8TraXX to determine whether or not a sound is allowed to be interrupted
while playing and start over, or if it should keep playing through to completion
and ignore incoming play requests.
Sound numbers 1001 to 1511 are uninterruptible, meaning that repeated play
requests will not cause the sound to start over from the beginning while playing.
An example of where this might be used is in a museum kiosk, where a guest
trips a break-beam sensor to start an audio presentation. The audio will continue
playing through, even though the guest might continually trip the sensor while
listening to the presentation.
Sound numbers 1 to 511 are interruptible, meaning that repeated play requests
during playback will cause the sound to start over. An example of where this
might be used is in a shooting gallery, where you want the sound to be heard
every time a gun’s trigger is pulled.
The parallel play inputs 1 through 8 will either play sound numbers 1 through 8,
or sound numbers 1001 through 1008, whichever it finds first. If the sound
number is 1001 through 1008, the sound will play in uninterruptible mode. If the
sound number is 1 through 8, the sound will play in interruptible mode.
Important Note: When using a PC to copy your audio files to the media, avoid
copying files after performing delete operations . This will cause the media to
become fragmented and the 8TraXX will malfunction during playback. Always
format the media in the 8TraXX first, and then copy files to it all at once.
