** Samples          Number of samples to calculate.
** ScaleLeft        Left volume multiplier.
** ScaleRight       Right volume multiplier (not used for mono sounds).
** StartPointLeft   Sample value from last session, for interpolation. Update!
** StartPointRight  Sample value from last session, for interpolation. Update!
** Src              Pointer to source samples.
** Dst              Pointer to pointer to destination buffer. Update!
** FirstOffsetI     The offset value of the first sample (when StartPoint*

** Offset           The offset (fix-point). Update!
** Add              Add value (fix-point).
** StopAtZero       If true, abort at next zero-crossing.
