Using audio input
The Audio-in function in LightJockey is used to trig scenes in a sequence in the cue control. The
function relies on the Windows sound system, which means that the PC must be equipped with a
Windows compatible sound card with working drivers. The audio-in function must be enabled via the
Hardware setup dialog (Main Menu -> Setup -> Hardware Setup).
The audio-input from the sound card is analyzed via a separate module(Martin Audio Analyzer) before
information is passed to LightJockey. The module is an external application that is automatically
launched when LightJockey starts up. If the Analyzer for some reason is closed down it may be
restarted via the Audio in menu on the main desktop.

Adjusting Windows audio properties
Since the audio-in uses the Windows sound system, it might be necessary to adjust the Windows
audio properties. Usually, when Windows installs drivers for sound cards it also installs a volume or
play control that usually lies with a small icon in the tray on the Windows taskbar. Depending on
which features are supported by the actual sound card and drivers, the play control may support more
or less features. If the PC contains more than one audio-input device, different devices may be
selected via the sound device selector. Note that the Microsoft Sound Mapper is not a physical
device. Selecting the sound mapper will always use the default/primary sound device in the system.
Usually sound cards supports numerous audio inputs such as microphone, Line-in and CD-ROM - but
the support for different input sources may vary with the actual sound hardware, especially on laptop a
PC. Also note that some sound cards/drivers may limit the number of input sources that may be used
at any one time.
An example of a Windows play control
Use the play control to ensure that the input source is enabled (not muted) and to adjust the input
level of the source. Before adjusting the input level, switch the Audio Analyzer into real-time view (
View -> Show -> Input -> Real-Time). he real-time view continually shows a small portion of the
sampled sound input. If the input is adjusted a level that is too high, there is a good chance that the
