KSSOUNDDETECTORPROPERTY structure (ksmedia.h)

  • Article

The KSSOUNDDETECTORPROPERTY structure specifies a node and an Event ID. All sound detector property calls into the driver are made using the KSSOUNDDETECTORPROPERTY structure.

Syntax

typedef struct {
  KSPROPERTY Property;
  GUID       EventId;
} KSSOUNDDETECTORPROPERTY, *PKSSOUNDDETECTORPROPERTY;

Members

Property

Specifies the property to get or set. This member is a structure of type KSPROPERTY.

EventId

Specifies the event ID GUID.

Remarks

The EventId is used to identify the different voice assistant/agents such as Cortana. By including the event id with all of the KSPROPERTY_SOUNDDETECTOR_* properties, each agent can be controlled separately, for example like arming "Cortana" without arming "Contoso".
