Remarks

Retrieves the number of encoding qualities (for Variable Bit Rate support) supported by Windows Media components for a given frequency and number of channels.

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

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

For further information about available encoding formats see the EncodeFormatsMan class.
