Extending and Looping

Extending the Initial Range

The initial range of an audio layer is based on the duration of the imported audio source, which is used as a source by this layer. However, this range can be extended by clicking and dragging the right edge of the layer block. This extended area will be darker and covered with diagonal lines.

As for composition layers, you can also:

• Time offset audio layers just by clicking and dragging the layer block

• Add a keyframe to the Enabled parameter to shut down the audio signal when Enabled is set to OFF then turn it ON again with another keyframe

Looping an Audio Source While Extending It

Selecting an audio item in the Project Panel will display its properties in the Inspector. There's an Audio Before and Audio After parameter that has several options that are set to Continue by default.

• Continue mode will maintain the last bit of information from the audio signal.

• Loop will set the file to be played in a loop without any time limit. This will allow the audio element to be extended indefinitely.

• Silence will cut any audio signal after the initial duration, even if the range is extended.

Before and After define the areas before and after the layer's initial range. If you extend the layer to the right, the After looping mode will be applied, whereas if you extend to the left the Before parameter will be used.

Audio Source in the Inspector

If you select an audio layer, you can select an audio source in the Selection Overview section of the Inspector. The Properties will display the same parameters as the reader used as a source by this layer, and by default all parameters will be shared between these two elements. Any changes made on either side will be reflected on both.

To unshare parameters in order to create variations that are local to a layer or to find out more about Sharing, please see this section.
