A first-pitch metric function based on a first audio sample and a second pitch-metric function based on a second audio sample may be determined. The first and second pitch-metric functions may have either local minima or local maxima that correspond to candidate pitch values of the first and the second audio samples, respectively. The first and the second pitch-metric functions may be transformed to generate a first and a second transformed pitch-metric function, respectively. A correlation function based on a correlation between the first and the second transformed pitch-metric function may also be determined. A lower-dimensionality representation of the correlation function may further be determined. The lower-dimensionality representation may convey information indicative of pitch dynamics between the first and second audio sample. A computing device having a processor and a memory may perform an action based on the information indicative of the pitch dynamics.
