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.

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

- 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
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.

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