Detailed Description

bc.yinstats external

This externals implements a statistical analysis of the raw output of pitches (usually given fed by the yin~ object). It examines all the different pitches over a time window and outputs the more probable pitch.

Member Function Documentation

bool bc_yinstats_addocc	(	t_bc_yinstats *	x,
		long	pitchin,
		double	ampin
	)

Adds a pitch to every enabled statistics agent.

If input pitch matches the pitch of the statistics agent then add as an occurence and sum the amplitude

Definition at line 245 of file bc.yinstats.c.

long bc_yinstats_addstat	(	t_bc_yinstats *	x,
		long	pitchin,
		double	ampin
	)

Enables a new statistics agent.

Sets also the lifetime of the agent

Definition at line 268 of file bc.yinstats.c.

void bc_yinstats_free

(

t_bc_yinstats *

x

)

Object destruction.

Remarks:

Frees all the clocks

Definition at line 160 of file bc.yinstats.c.

void * bc_yinstats_new	(	t_symbol *	s,
		long	argc,
		t_atom *	argv
	)

Object instantiation.

Allocate the memory for the number of statistics agents given as first argument

Definition at line 108 of file bc.yinstats.c.

Here is the call graph for this function:

void bc_yinstats_reset	(	t_bc_yinstats *	x,
		bc_statelem *	stat
	)

Resets a statistics agent.

After reset, the agents status is disabled

Definition at line 292 of file bc.yinstats.c.

Here is the call graph for this function:

void bc_yinstats_stop

(

t_bc_yinstats *

x

)

Stops all the statistics agents at once.

Outputs nothing.
