Monophonic Fundamental Frequency Extraction

Fundamental frequency estimation of monophonic acoustic signals is a very rich and active field of research. Similarly to a lot of signal processing techniques, fundamental estimation was first developped for, and applied to speech signals. One can literally find hundreds of methods in [Hess83]. It is also interesting to note that [Rabiner76], and [deCheveigné01] made an attempt to compare different commonly used fundamental frequency estimation techniques. This quick review, will not present all the different methods. Instead, we will give a general overview of the topic based on the model-level typology of algortihms proposed in [Klapuri04].
