The Variable Bitrate (VBR) quality used for WMA (Windows Media Audio) format.
Supported values are in the range from 0 (low quality) to 100 (high quality): note that, depending upon the chosen input format, not all of the values inside this range are supported.
The full list of VBR qualities, supported by a certain frequency and number of channels, can be obtained using the EncodeFormats.WMA.GetEncodingVBRQualitiesCountEx and EncodeFormats.WMA.GetEncodingVBRQualityEx methods.
This property is used only if the EncodeFormats.FormatToUse property is set to ENCODING_FORMAT_WMA and the EncodeFormats.WMA.EncodeMode property is set to WMA_ENCODE_VBR_QUALITY.
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.
