Perform an Audio Test
After verifying that the RADs and DRs are configured correctly and working properly, you should per-
form an audio test. You can perform this test the old-fashioned way by wandering about and checking
the actual audio, or you can perform your audio test from within the Halogen software. To do so, start
the audio and then view the audio flow in the Processing Map (in the Processing Workspace). Open out-
put block properties and view their meters in real time. Or, if needed, add a meter block where appro-
priate for verifying the audio. You can also, of course, view the Signal and Overload LEDs on the
RADs and/or the HAL to verify that the audio signal is flowing correctly.
Save the Final Configuration File
We already delivered our lecture on the benefits of saving your configuration to a backup file – so we
won’t do that again. Instead, we’ll just tell you how to do it.
1.
Connect to the HAL device.
From the
Device
menu in the Halogen application toolbar, click
Connect
. In the
dialog box that appears, find the HAL device you want.
Click the
Connect
button associated with that HAL device.
2. From the
File
menu in the application toolbar, click
Save
or
Save As
.
3. When prompted, type the filename for this new configuration file. All Halogen configuration
filenames have an extension of
.hal
and, by default, are stored in the
C:\\Users\-
<username>\My Documents\Halogen Configs
folder. You can save the file to
a different location if desired, however.
Creating a Verification Configuration
Even if you do not have a pre-defined configuration file or the necessary information to create one for
your system, you can still test that the installed devices can send and receive audio signals. Use Hal-
ogen to create a simple verification configuration. This procedure assumes that you have installed and
connected the HAL and all the EXPs, RADs, and DRs, and have verified that the devices are com-
municating successfully (by viewing their LEDs or LCD screens.)
To perform a simple verification of audio signal receipt and transmission:
1. Open the Halogen software and view the Hardware Workspace.
2. Connect to the HAL you want to test. Because you have not loaded a configuration file into
the device but you have installed the RADs and DRs, the software reports device mismatches.
HAL is reporting that it is not configured for the RADs and DRs it detects on its ports.
3. To quickly fix the device mismatch problems, hover your cursor over each Device Mismatch
message. A tooltip appears telling you what device HAL detects on that port:
Configure the port to match the detected device. You can do so by dragging and dropping the
correct RAD or DR from the hardware palette onto the port, or you can select the correct RAD
or DR from the Model Picker (accessed by clicking the arrow on the right side of the port).
