Windows.Media.Audio Namespace

Provides APIs for routing, mixing, and processing audio.

Classes

AudioDeviceInputNode	Represents a node in an audio graph node that inputs audio data into the graph from an audio device such as a microphone or external audio interface.
AudioDeviceOutputNode	Represents a node in an audio graph node that outputs audio data from the graph to an audio device such as a speaker or external audio interface.
AudioEffectsPackConfiguration
AudioFileInputNode	Represents a node in an audio graph node that inputs audio data into the graph from an audio file.
AudioFileOutputNode	Represents a node in an audio graph node that outputs audio data from the graph to an audio file.
AudioFrameCompletedEventArgs	Represents arguments for an AudioFrameCompleted event.
AudioFrameInputNode	Represents a node in an audio graph node that inputs audio data into the graph from app-implemented code that generates audio samples programmatically.
AudioFrameOutputNode	Represents a node in an audio graph node that outputs audio data from the graph into app-implemented code.
AudioGraph	Represents an audio graph of connected input, output, and submix nodes that manipulate and route audio.
AudioGraphBatchUpdater	An object that, upon creation with CreateBatchUpdater, causes all subsequent modifications to all nodes in an AudioGraph to be accumulated and then committed once your app closes or disposes of the batch updater object.
AudioGraphConnection	Represents a connection within an audio graph.
AudioGraphSettings	Represents initialization settings for an audio graph. Set the properties of this object to your desired values and then call AudioGraph.CreateAsync to create a new audio graph instance with the specified settings.
AudioGraphUnrecoverableErrorOccurredEventArgs	Represents arguments for an UnrecoverableErrorOccurred event.
AudioNodeEmitter	Describes the position and other physical characteristics of an emitter from which the audio of an AudioGraph node is emitted when spatial audio processing is used.
AudioNodeEmitterConeProperties	Describes the cone shape used by an AudioNodeEmitterShape. At the inner angle of the cone, audio is not attenuated at all. At the outer angle of the cone, audio is fully attenuated.
AudioNodeEmitterDecayModel	Represents the model used to compute the distance-based attenuation of a signal from an AudioNodeEmitter.
AudioNodeEmitterNaturalDecayModelProperties	Describes the characteristics of a natural AudioNodeEmitterDecayModel.
AudioNodeEmitterShape	Describes the shape in which an AudioNodeEmitter emits audio.
AudioNodeListener	Describes the position and other physical characteristics of a listener from which the audio output of an AudioGraph node is heard when spatial audio processing is used.
AudioPlaybackConnection	Represents a connection that allows a remote device to stream audio to a Windows device.
AudioPlaybackConnectionOpenResult	The value returned from a call to Open or OpenAsync that indicates whether the call was successful and, if not, provides an extended error code.
AudioStateMonitor	Allows a UWP app to determine if any of the app's audio streams are currently being muted or having their volume reduced by the system.
AudioSubmixNode	Represents an audio submix node that mixes the output of one or more nodes into single output that can be connected to output nodes or other submix nodes.
CreateAudioDeviceInputNodeResult	Represents the result of attempting to create an audio device input node.
CreateAudioDeviceOutputNodeResult	Represents the result of attempting to create an audio device output node.
CreateAudioFileInputNodeResult	Represents the result of attempting to create an audio file input node.
CreateAudioFileOutputNodeResult	Represents the result of attempting to create an audio file output node.
CreateAudioGraphResult	Represents the result of attempting to create an audio graph.
CreateMediaSourceAudioInputNodeResult	Represents the result of attempting to create a MediaSourceAudioInputNode.
EchoEffectDefinition	Represents an echo effect definition supported by the audio graph.
EqualizerBand	Represents an equalizer band for the equalizer effect.
EqualizerEffectDefinition	Represents an equalizer effect definition supported by the audio graph.
FrameInputNodeQuantumStartedEventArgs	Provides data for the AudioFrameInputNode.QuantumStarted event. This event is raised when the audio graph containing the audio frame input node is ready to begin processing a new quantum of data.
LimiterEffectDefinition	Represents a limiter effect definition supported by the audio graph.
MediaSourceAudioInputNode	Represents a node in an audio graph that inputs audio data into the graph from a MediaSource object.
ReverbEffectDefinition	Represents a reverberation effect definition supported by the audio graph.
SetDefaultSpatialAudioFormatResult	Represents the result of attempting to set a default spatial audio format.
SpatialAudioDeviceConfiguration	Represents a audio device, providing information and control for its current spatial audio setup.
SpatialAudioFormatConfiguration	Provides a way to configure Spatial Audio Formats.
SpatialAudioFormatSubtype	Helper class to retrieve the GUIDs for known spatial audio formats.

Interfaces

IAudioInputNode	Defines an audio input node.
IAudioInputNode2	The interface implemented by audio input nodes that support spatial audio.
IAudioNode	Defines an audio node.
IAudioNodeWithListener	The interface implemented by audio nodes that support a spatial audio listener.
