Enable/disables the automatic detection of silent sound's portions during the loading of a sound through one of the many methods having the "Load" prefix like LoadSound or LoadSoundFromMemory: the automatic silence detection is disabled by default.
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.
When the automatic silence detection is enabled, 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.
When the automatic silence detection is disabled, the loaded song silence can be requested at any time calling the SilenceDetectionOnPlayerRequest method.
For further details about silence detection management see the How to detect silent portions of sound files tutorial.
