Errata for the scientific paper:
N. Juillerat, B. Hirsbrunner, "Low Latency Audio Pitch Shifting in the Frequency Domain" , IEEE International Conference on Audio, Language and Image Processing, ICALIP 2010, 2010

- In Equation (2), the "N" factor must be removed from the denominator. The reference implementation available at https://www.pitchtech.ch uses the correct formula.
