virtual void NLSOUND::CSourceDSound::setAlpha (  double    a )  [inline, virtual]
 

Set the alpha value for the volume-distance curve.

alpha = 0.0: the volume will decrease linearly between 0dB and -100 dB alpha = 1.0: the volume will decrease linearly between 1.0 and 0.0 (linear scale) alpha = -1.0: the volume will decrease inversely with the distance (1/dist). This is the default used by DirectSound/OpenAL

For any other value of alpha, an interpolation is be done between the two adjacent curves. For example, if alpha equals 0.5, the volume will be halfway between the linear dB curve and the linear amplitude curve.
