Detailed Description

This processing takes an array of circular peaks with position at pitch units [0,12) and corrects them to be tunned given a tunning center and a reference tune. The tunning center is the detected tunning center within a single semitone [0,1). The reference tunning is the reference we take for pitch 0.

Todo:

be more explicit on the meaning of reference tunning.

Member Function Documentation

unsigned Simac::CircularPeakTunner::chromagramToSemitone	(	double	tunning,
		double	peakPosition
	)		[inline]

Todo:

Migrate this function tests to one bin per semitone Given a tunning (in chromogram bins) and a peak position, it returns the semitone pitch index being the zero semitone the one containing the reference tunning.

Parameters:

tunning

is a [0,3) number that indicates the detected center of a semitone inside a chromogram semitone triplet.
