Function Documentation

cmpfunc()

int cmpfunc	(	const void *	a,
		const void *	b
	)

cmpfunc compares two values.

Parameters

a	(in) First value
b	(in) Second value

Returns

: comparison result

Definition at line 130 of file TempoFunctions.h.

ComputeTempo()

void ComputeTempo	(	STempo *	TEMPO,
		int	current,
		int	pos_min,
		int	count_min,
		int *	states_corr,
		int	NStates
	)

ComputeTempo calculates the tempo for current frame using gaussian filter.

Parameters

TEMPO	(inout) Struct for control the tempo
current	(in) Current frame
pos_min	(in) The position of the minimum in Current frame
count_min	(in) Times pos_min verify one hypothesis over vector states_time_e
states_corr	(in) states_corr vector
NStates	(in) Number of states

Returns

: None, it is void

Definition at line 401 of file TempoFunctions.h.

ComputeTempoRL()

void ComputeTempoRL	(	STempoRL *	TEMPO,
		int	current,
		int	pos_min,
		int	count_min,
		int *	states_corr
	)

ComputeTempoRL calculates tempo and controls synthesizer speed using linear regression.

Parameters

TEMPO	(inout) Struct for control the tempo
current	(in) Current frame
pos_min	(in) Estimated score position (frame) in Current frame
count_min	(in) Estimated score position (state) in Current frame
states_corr	(in) states_corr vector

Returns

: None, it is void

Definition at line 466 of file TempoFunctions.h.

TheilSenRegression()

MyType TheilSenRegression	(	int *	x,
		int *	y,
		int	L,
		bool *	outlier
	)

TheilSenRegression computes Theil-Sen linear regression.

Parameters

x	(in) Audio time of anchor points
y	(in) Score time of anchor points
L	(in) Number of the last anchor point
outlier	(out) 1 if last anchor point is an outlier, 0 otherwise

Returns

: Estimated slope
