Requests the calculation of silent portions at the start and end of the sound loaded inside the given player: useful when the automatic silence detection has been disabled through a call to the SilenceDetectionOnPlayerLoadAutoSet method.
This method doesn't work with sounds with more than 2 channels (5.1 or 7.1) or if the EnableMixingFeatures property has been set to false.
Silence detection works inside a secondary thread so, once detected, the container application will be notified about initial and final positions of silent portions at the start and end of loaded songs through the CallbackForPlayersEvents delegate which is invoked with the nEvent parameter set to EV_SILENCE_AVAIL.
If you need to perform silence detection inside the main thread and to have silence positions immediately available after returning from the method call you can use the SilenceDetectionOnPlayer method.
For further details about silence detection management see the How to detect silent portions of sound files tutorial.
