AudioGraph.CreateFileInputNodeAsync Method

Definition

Namespace:

Windows.Media.Audio

Overloads

CreateFileInputNodeAsync(IStorageFile)	Creates an AudioFileInputNode that inputs audio data into the audio graph from a storage file.
CreateFileInputNodeAsync(IStorageFile, AudioNodeEmitter)	Creates a spatial audio-enabled AudioFileInputNode that inputs audio data into the audio graph from a storage file.

CreateFileInputNodeAsync(IStorageFile)

Creates an AudioFileInputNode that inputs audio data into the audio graph from a storage file.

public:
 virtual IAsyncOperation<CreateAudioFileInputNodeResult ^> ^ CreateFileInputNodeAsync(IStorageFile ^ file) = CreateFileInputNodeAsync;

/// [Windows.Foundation.Metadata.RemoteAsync]
IAsyncOperation<CreateAudioFileInputNodeResult> CreateFileInputNodeAsync(IStorageFile const& file);

[Windows.Foundation.Metadata.RemoteAsync]
public IAsyncOperation<CreateAudioFileInputNodeResult> CreateFileInputNodeAsync(IStorageFile file);

function createFileInputNodeAsync(file)

Public Function CreateFileInputNodeAsync (file As IStorageFile) As IAsyncOperation(Of CreateAudioFileInputNodeResult)

Parameters

file

IStorageFile

A StorageFile object representing the audio file associated with the input node.

Returns

IAsyncOperation<CreateAudioFileInputNodeResult>

An asynchronous operation that returns a CreateAudioFileInputNodeResult on completion. This object exposes a Status property, that indicates either that the operation was successful or the reason why the operation failed. The FileInputNode property provides a reference to the created output node on success.

CreateFileInputNodeAsync(IStorageFile, AudioNodeEmitter)

Creates a spatial audio-enabled AudioFileInputNode that inputs audio data into the audio graph from a storage file.

public:
 virtual IAsyncOperation<CreateAudioFileInputNodeResult ^> ^ CreateFileInputNodeAsync(IStorageFile ^ file, AudioNodeEmitter ^ emitter) = CreateFileInputNodeAsync;

/// [Windows.Foundation.Metadata.Overload("CreateFileInputNodeWithEmitterAsync")]
/// [Windows.Foundation.Metadata.RemoteAsync]
IAsyncOperation<CreateAudioFileInputNodeResult> CreateFileInputNodeAsync(IStorageFile const& file, AudioNodeEmitter const& emitter);

[Windows.Foundation.Metadata.RemoteAsync]
public IAsyncOperation<CreateAudioFileInputNodeResult> CreateFileInputNodeAsync(IStorageFile file, AudioNodeEmitter emitter);

function createFileInputNodeAsync(file, emitter)

Public Function CreateFileInputNodeAsync (file As IStorageFile, emitter As AudioNodeEmitter) As IAsyncOperation(Of CreateAudioFileInputNodeResult)

Parameters

file

IStorageFile

A IStorageFile object representing the audio file associated with the input node.

emitter

AudioNodeEmitter

An object that describes the position and other physical characteristics of the emitter from which the node's audio is emitted when spatial audio processing is used.

Returns

IAsyncOperation<CreateAudioFileInputNodeResult>

An asynchronous operation that returns a CreateAudioFileInputNodeResult on completion. This object exposes a Status property, that indicates either that the operation was successful or the reason why the operation failed. The FileInputNode property provides a reference to the created input node on success.

Attributes

OverloadAttribute RemoteAsyncAttribute

Windows requirements

Device family	Windows 10 Anniversary Edition (introduced in 10.0.14393.0)
API contract	Windows.Foundation.UniversalApiContract (introduced in v3.0)
App capabilities	backgroundMediaRecording

Remarks

To create a file input node with an emitter, the audio file must be encoded in mono at 48kHz.
