Timeline Audio

It is possible for the LPC X, VLC, VLC+ to output Audio from the Stereo connectors on the rear.

This audio will then be played synchronously with the lighting on the timeline.

Managing Timeline Audio

to Enable Timeline Audio

Timeline Audio is a feature that must be enabled from the Project Features page, and requires a suitable controller in the project.

To Import Audio

Audio is imported in the same way as video clips; from Mapping or the Media Preset library.

To mute timeline audio during simulation

While simulating a timeline, it may be desirable to mute the audio temporarily. This can be done by selecting the Mute button on the Mode toolbar.

To Set the Default volume of the Timeline Audio

The volume of the Timeline Audio output is managed at a controller level.

To set the Default level, go to the controller's interface settings. This can be adjusted at runtime using the Set Volume Action.

Imported audio should be normalised to avoid having to chance volume for different timelines.

Timeline Audio Properties

When an Audio Media preset is added to a timeline, the following properties will be available:

• Start
• End
• Audio category

Start

This is the start point of the audio, this can be used to not play the start of the audio track

End

This is the end point of the audio, this can be used to not play the end of the audio track

Audio category

There are two categories available, which treat the audio in different ways:

Background

A background audio track will be played back normally, and if another background track is started, the first will be stopped.

Alert

An Alert track will playback over the top of a Background track, and will stop a playing alert track if another alert track is started.
