Remarks
Retrieves a specific encoding quality (for Variable Bit Rate support) for a given native resampling format.
The number of available bitrates can be obtained using the EncodeFormats.WMA.GetEncodingVBRQualitiesCount 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.

Parameter
|
Description
|
|
|
nInputDevice
|
Number representing the zero-based index of the input device
|
nFormatIndex
|
Number representing the zero-based index of the native resampling format.
The number of native resampling formats supported by the given input device can be obtained using the EncodeFormats.ResampleNativeFormatsGetCount method and their friendly description can be obtained using the EncodeFormats.ResampleNativeFormatGetDesc method
|
nQualityIndex
|
Number representing the zero-based index of the bitrate quality
|
Return value
