Overloads
| Name | Description |
|---|---|
| CreateFileOutputNodeAsync(IStorageFile) |
Creates a new AudioFileOutputNode that outputs audio data from the audio graph to the specified storage file. |
| CreateFileOutputNodeAsync(IStorageFile, MediaEncodingProfile) |
Creates a new AudioFileOutuputNode that outputs audio data from the audio graph to the specified storage file. |
CreateFileOutputNodeAsync(IStorageFile)
Creates a new AudioFileOutputNode that outputs audio data from the audio graph to the specified storage file.

public IAsyncOperation<CreateAudioFileOutputNodeResult> CreateFileOutputNodeAsync(IStorageFile file);function createFileOutputNodeAsync(file)Public Function CreateFileOutputNodeAsync (file As IStorageFile) As IAsyncOperation(Of CreateAudioFileOutputNodeResult)Parameters
- file
- IStorageFile
A StorageFile to which audio data is written.
Returns
An asynchronous operation that returns a CreateAudioFileOutputNodeResult on completion. This object exposes a Status property, that indicates either that the operation was successful or the reason why the operation failed. The FileOutputNode property provides a reference to the created output node on success.

Remarks
The file output node created by this method defaults to a WAV file format with the same AudioEncodingProperties properties as the AudioGraph to which it belongs. To create a file output node with custom encoding properties use the CreateFileOutputNodeAsync(IStorageFile, MediaEncodingProfile) overload.

- file
- IStorageFile
A StorageFile to which audio data is written.
- fileEncodingProfile
- MediaEncodingProfile
A MediaEncodingProfile that determines the format of the output file.
Returns
An asynchronous operation that returns a CreateAudioFileOutputNodeResult on completion. This object exposes a Status property, that indicates either that the operation was successful or the reason why the operation failed. The FileOutputNode property provides a reference to the created output node on success.
