		int	count
	)

inlinenoexcept

Adds source samples scaled by a linear gain ramp into a destination.

Same ramp convention as applyGainRamp: sample i uses gainStart + i * (gainEnd - gainStart) / count, spanning [gainStart, gainEnd) across the block. count <= 0 is a no-op.

void dspark::simd::applyGainRamp	(	float *DSPARK_RESTRICT	data,
		float	gainStart,
		float	gainEnd,
		int	count
	)

inlinenoexcept

In-place linear gain ramp (the canonical click-free fade primitive).

Sample i is scaled by gainStart + i * (gainEnd - gainStart) / count, so the ramp covers [gainStart, gainEnd) across the block: the last sample sits one step below gainEnd. For a continuous fade across consecutive blocks, start the next block at gainEnd. count <= 0 is a no-op.
