AudioVBR

Description

Sets whether constant or variable bitrates are to be used to encode the audio stream.

Syntax

[C#/C++]
public Bool AudioVBR;

[VB.NET]
Public Property AudioVBR As Boolean

Remarks

A codec may support variable or constant bitrate encoding, or both.

To find which audio codecs support what type of bitrate encoding, use the IWMCodecInfo3 interface defined in the Windows Media Format 9.5 SDK. Its SetCodecEnumerationInfo method can be used to return codecs that support either variable or constant bitrates.

See Exporting to Windows Media Video and Enumerating Audio Codecs for some sample code and more help, and see the Windows Media Format 9.5 SDK help at http://msdn.microsoft.com.
