The DirectSound3DListener.SetRolloffFactor method sets the rolloff factor.

object.SetRolloffFactor(rolloffFactor As Single, _
    applyFlag As CONST_DS3DAPPLYFLAGS)

Parameters

object

rolloffFactor

Rolloff factor.

applyFlag

Value that indicates when the setting should be applied. This value must be one of the constants of the CONST_DS3DAPPLYFLAGS enumeration.
