AudioAvgBytesPerSec Property

Summary

Gets the average transfer rate, in bytes per second, for the audio format in the current audio stream of the source media file.

Syntax

C++

public int AudioAvgBytesPerSec { get; }

Public ReadOnly Property AudioAvgBytesPerSec As Integer

public: 
property int AudioAvgBytesPerSec { 
   int get(); 
}

Property Value

A value representing the average transfer rate for the audio format of the current audio stream, in bytes per second.

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.
