References on F0 Estimation

An often-cited book on classical methods for pitch detection, particularly for voice, is that by Hess [193]. The harmonic comb method can be considered an approximate maximum-likelihood pitch estimator, and more accurate maximum-likelihood methods have been worked out [114,551,379,380]. More recently, Klapuri has been developing some promising methods for multiple pitch estimation [256,255,254].^7.12A comparison of real-time pitch-tracking algorithms applied to guitar is given in [262], with consideration of latency (time delay).
