Playback
Synchronous Playback
RideTraXX is capable of sample synced audio playback on all 16 channels.
To start synchronous playback, you first send search commands to queue
each file on its desired output channel. Once all of your desired channels are
searched(queued), sending an
SP (Sync Play) or SL (Sync Loop) command
will start playback of all searched files.
For example, if we wanted to start synchronous playback of files 1-4 on
channels 4-7 respectively, we would send the following series of commands:
1C4SE
2C5SE
3C6SE
4C7SE
SP
After the SP command is received, playback will start in exactly 3 seconds
(+/- 10ms). No delay is required between the search commands and the SP
command. To execute the required actions with a single command, the
search and sync play commands can be put into a playlist, and the playlist
started as the System Playlist.
More details on these commands can be found in the
Command Protocol
section of this manual.
Note: During the 3 seconds between when a SP command is received and
the audio playback is started, all the audio outputs of RideTraXX will be
silent.
Interruptible versus Uninterruptible Operation
In a play command, you can specify uninterruptible playback, 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.
If not specified otherwise in the play command, files play as 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.
See the Command Protocol section for details on how to specify interruptible
vs. uninterruptible mode in your commands.
