Remarks

An audio frame typically contains multiple audio samples. Access the audio data by calling LockBuffer which returns an AudioBuffer.

Constructors

AudioFrame(UInt32)

Initializes a new instance of the AudioFrame class.

Properties

Duration

Gets or sets the duration of the audio frame.
ExtendedProperties

Gets the extended property set which enables getting and setting properties on the AudioFrame.
IsDiscontinuous

Gets or sets a value that indicates whether an audio frame is the first frame after a gap in the stream.
IsReadOnly

Gets a value indicating whether the audio frame is read-only.
RelativeTime

Gets or sets the relative time of the frame within the audio stream.
SystemRelativeTime

Gets or sets a timestamp that is relative to the system and is correlatable across multiple media sources on the same device.
Type

Gets a string indicating the type of audio data the audio frame contains.

Methods

Close()

Disposes of the object and associated resources.
Dispose()

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
