Detailed Description

stores info about the pitch currently being detected

Definition at line 40 of file PitchDetector.h.

List of all members.

Public Member Functions
	PitchInfo ()
	constructor -- sets everything to 0 (additional initialization is done for each pitch_info entry during doStart())
Public Attributes
float	freq
	frequency of this pitch (calculated on instantiation)
float	sigma
	standard dev to use (sqrt(var)), calc'd on start
float	local_max
	[0,1] value: how much stronger it is than neighbors, else zero
float	global_max
	[0,1] value: how much stronger than mean if global max, else zero
float	overtone
	value in [0,1] with confidence that it is overtone
float	confidence
	value in [0,1] with confidence that this is a pitch, not noise (should confidence have a rolling average as well?)
float	amplitude
	rolling average amplitude
unsigned int	duration
	number of windows it has been on
