Digital Messages
Digital messages can be created in the Job Details section of the configurator. To create a
digital message go to the Audio section of the Job Details window and press the Set Up
button. The Audio Setup window appears. In this window press the Manage Messages button.
The Manage Messages menu lists each of the digital messages that can be used for the job
being configured. A new digital message can be created and added to the list using the Add
button. An existing digital message can be modified by selecting it and pressing the Edit
button. A digital message can be deleted from the list by pressing the remove button.
In the Manage Messages window press the Add button or select a message to edit then press
the Edit button. Refer to the figure below.
In the new window either press the Import button and select an audio file to include in the
message or select an audio clip from the files already imported into the Audio Clips menu. All
audio files must be in .wav format. The .wav format must be sampled at 11.025 KHz, 16-bit
mono, ADPCM 4-bit. This format is suited for compressing voice. Alternatively,
PCM (RAW) 16-
bit mono can be used for non-voice messages such as a whoop signal or sweep.
A program
called Audacity is able to convert most audio file formats into the required .wav format. The
software is freeware and can be downloaded from http://audacity.sourceforge.net/.
Once an audio clip has been imported into the Audio Clips list it can be used to compose a
message. A message can be composed out of a single or out of multiple audio files. Select the
audio clip and move it over to the Composition list by pressing the dual chevron button beside
the Audio Clips list. The audio files in the Composition list can be reordered by selecting them
in the list and pressing the Up and Down buttons. The audio clips can be removed from the
Composition list by selecting them and pressing the Del button. An audio clip can also be set
to repeat a certain number of times, to do this double-click on the count column beside the
audio clip in the Composition list and enter the number of times to repeat it. The entire
