Efficient Pitch Detection Techniques for Interactive Music
Patricio de la Cuadra, Aaron Master, Craig Stuart Sapp · University of Michigan Library Repository · 2001
Several pitch detection algorithms are examined for use in interactive computer-music performance.We define criteria necessary for successful pitch tracking in real-time and survey four tracking techniques: Harmonic Product Spectrum (HPS), Cepstrum-Biased HPS (CBHPS), Maximum Likelihood (ML), and the Weighted Autocorrelation Function (WACF).
