Events > SilencePositionAvailable event

Remarks

Occurs when the control has completed the detection of silent portions at the start and end of a loaded song.

Silence detection is performed automatically if the SilenceDetectionOnPlayerLoadAutoSet method has been previously called or on-demand after a call to the SilenceDetectionOnPlayerRequest method.

For further details about silence detection management see the How to detect silent portions of sound files tutorial.

For further details about synchronization through Events see the How to synchronize the container application through events tutorial.
