A method for estimating the normalised pitch variation is described. While pitch tracking is a classical problem, in applications where the pitch magnitude is not required but only the change in pitch, all the main problems of pitch tracking can be avoided, such as octave jumps and intricate peak-finding heuristics. The presented approach is efficient, accurate and unbiased. It was developed for use in speech and audio coding for pitch variation compensation, but can also be used as additional information for pitch tracking.
