Remarks

This property is updated automatically when the CurrentStream property is set to an audio stream. This property will not be updated if the current stream is not an audio stream. The current source media file, found in the SourceFile property, is the file that the MediaInfo object gets information for. The SourceFile property must be set before retrieving information from any of the other MediaInfo properties.

Requirements

Target Platforms: Microsoft .NET Framework 2.0, Windows 2000, Windows XP, Windows Server 2003 family, Windows Server 2008 family, Windows Vista, Windows 7
