Syntax
[Visual Basic] Public Function SetDownmixFilterQuality ( nQuality as Int16 ) as enumErrorCodes |
[C#] public enumErrorCodes SetDownmixFilterQuality ( Int16 nQuality ); |

Parameter |
Description |
|
|
nQuality |
Number representing the quality of the anti-aliasing filter expressed in percentage. Accepted values are from 0 to 100: - value 0 (default) disables the anti-aliasing filter - values from 1 to 100 enable the anti-aliasing filter: the higher the value, the best the final result but, obviously, higher values will require some more CPU. |
