tSampleQueueEvent

enum tSampleQueueEvent : uint8_t

specifies the several types of events

SQE_SampleQueueInserted	Used when a Sample is added to the Queue. nParam1 set to 1. nParam2 is not used.
SQE_SampleQueueErased	Used when a Sample is deleted from Queue. nParam1 set to the current erasing count of this action (the number of call by one action starting with 1). nParam2 is used for the reason of deletion (0 = MaxSize was reached, 1 = TimeRange was reached, 2 = Pop function was called, 3 = Queue was cleared).
