Properties

ConsumeInput	Gets or sets a value indicating if the audio device output node consumes input.
Device	Gets information about the audio device.
EffectDefinitions	Gets the list of effect definitions for the audio device output node. The effects in the list process audio data that flows through the node in the order in which they appear in the list.
EncodingProperties	Gets the encoding properties for the audio device output node.
Listener	Gets or sets the AudioNodeListener that describes the position and other characteristics of the listener from which the AudioDeviceOutputNode audio is heard when spatial audio processing is used.
OutgoingGain	Gets or sets the outgoing gain for the audio device output node.

Methods

Close()	Closes the audio device output node and disposes of associated resources.
DisableEffectsByDefinition(IAudioEffectDefinition)	Disables all effects in the EffectDefinitions list with the specified effect definition.
Dispose()	Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
EnableEffectsByDefinition(IAudioEffectDefinition)	Enables all effects in the EffectDefinitions list with the specified effect definition.
Reset()	Resets the audio device output node.
Start()	Starts the audio device output node.
Stop()	Stops the audio device output node.
