Function Documentation

tZeroCrossingCounter_init()

void tZeroCrossingCounter_init	(	tZeroCrossingCounter * const	counter,
		int	maxWindowSize,
		LEAF *const	leaf
	)

Initialize a tZeroCrossingCounter to the default mempool of a LEAF instance.

Parameters

counter	A pointer to the tZeroCrossingCounter to initialize.
maxWindowSize	The max and initial size of the window.
leaf	A pointer to the leaf instance.

tZeroCrossingCounter_initToPool()

void tZeroCrossingCounter_initToPool	(	tZeroCrossingCounter * const	counter,
		int	maxWindowSize,
		tMempool *const	mempool
	)

Initialize a tZeroCrossingCounter to a specified mempool.

Parameters

counter	A pointer to the tZeroCrossingCounter to initialize.
maxWindowSize	The max and initial size of the window.
mempool	A pointer to the tMempool to use.

tZeroCrossingCounter_free()

void tZeroCrossingCounter_free

(

tZeroCrossingCounter * const

counter

)

Free a tZeroCrossingCounter from its mempool.

Parameters

counter

A pointer to the tZeroCrossingCounter to free.

tZeroCrossingCounter_tick()

float tZeroCrossingCounter_tick	(	tZeroCrossingCounter * const	counter,
		float	input
	)

Tick the tZeroCrossingCounter.

Parameters

counter	A pointer to the relevant tZeroCrossingCounter.
input	The input sample.

Returns

The amount of zero crossings as a proportion of the window.

tZeroCrossingCounter_setWindowSize()

void tZeroCrossingCounter_setWindowSize	(	tZeroCrossingCounter * const	counter,
		float	windowSize
	)

Set the size of the window. Cannot be greater than the max size given on initialization.

Parameters

counter	A pointer to the relevant tZeroCrossingCounter.
windowSize	The new window size.
