Line in

Edward Updated by Edward

The PC Line-in triggers can use any audio source to control NEO. An audio event can trigger a cue GO, fire a shortcut, flash a submaster or run a command.

 

The “Line in” tab provides the ability to set the audio source and then create multiple events. Each event is determined by the frequency range, trigger level, level type and minimum time between events.

 

For NEO to listen to the selected audio source you must enable it by clicking on “Enable Audio Triggers”.

Above the event grid is a graphic display of the incoming audio frequencies. This is known as the audio spectrum and shows the response to frequencies from 0 to the maximum frequency set.

Input Audio Device – Select the audio source device you want to use to trigger the system. This is the system device that will be listened to and shown in the display.

 

Maximum Frequency – The maximum frequency determines the upper sample limit the software will listen to. The default is just over 5kHz. A higher maximum frequency will require more CPU to sample continuously.

 

Creating an event

An event in the audio trigger system is a list of conditions that when met will trigger the event. The event itself will also have settings that determine what will happen.

 

Frequency Range (Low Freq, High Freq) – The frequency range for the event will limit the area of the spectrum that is listened to. This is best understood by looking at the red lines in the spectrum display. The left red line is the low frequency and the right red line is the high frequency. You can also use your mouse to click and drag either red line to adjust the frequency.

 

Trigger Level – Select the audio level in percentage of the maximum that will trigger the event. This is represented as the yellow line running across the spectrum display. You can also use your mouse to click and drag to move the line and adjust the level.

 

Level Type – Use the level type to select how the trigger level is used. You can select between “Average Frequency” or “Any Frequency”. If the level type is set to average frequency, then all the levels between the frequency range specified are averaged. If the average exceeds the level set, then the trigger is fired. If the level type is set to any frequency, then the trigger will fire if any level between the frequency range exceeds the trigger level.

 

Min Time Between – Set the minimum time between trigger events. This option stops the trigger from firing continuously if the level is exceeded for a long period of time.

 

Action – The action setting specifies what will happen when the trigger occurs. This can be set to Global, Shortcut, Submaster Flash or Command. Setting this to Global will run any cue that is primed with “Line in” as its trigger. Shortcut will run the shortcut specified in the Shortcut/Submaster field. Submaster Flash will set the specified submaster to full for the Flash Duration and then return it to its previous level.

 

Command will execute the command line text specified in the Command field.

 

Enabled – You can create several events and then enable only those that work for the input source being used.
