EncodeFormats.WMA.GetEncodingBitratesCount method

Previous pageReturn to chapter overviewNext page



Retrieves the number of supported encoding constant bitrates (CBR) for a given native resampling format.

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


This method can be called only when the Status property is different from RECORD_STATUS_NOT_READY.


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.
