Previous pageReturn to chapter overviewNext page

Remarks

 

Retrieves the number of encoding bitrates (Constant Bitrate or CBR) supported by Windows Media components for a given frequency and number of channels.

Each of the supported bitrates can be obtained at a later time using the EncodeFormats.WMA.GetEncodingCBR method.

 

For further details about encoding in WMA format refer to the WMA object section.

For further information about available encoding formats see the EncodeFormats object.
