explicit

creates a new instance and initializes it with the provided values.

Parameters

duration

duration of the fade-in in seconds.

LinearFadeIn() [3/3]

HephAudio::LinearFadeIn::LinearFadeIn	(	double	duration,
		double	startTime )

creates a new instance and initializes it with the provided values.

Parameters

duration	duration of the fade-in in seconds.
startTime	time, in seconds, of the first audio frame the effect will be applied to.

~LinearFadeIn()

virtual HephAudio::LinearFadeIn::~LinearFadeIn ( )

virtualdefault

releases the resources and destroys the instance.
