abstract = "Pitch Estimation, also known as Fundamental Frequency
(F0) estimation, has been a popular research topic for
many years, and is still investigated nowadays. This
paper presents a novel approach to the problem of Pitch
Estimation, using Cartesian Genetic Programming (CGP).
We take advantage of evolutionary algorithms, in
particular CGP, to evolve mathematical functions that
act as classifiers. These classifiers are used to
identify piano notes' pitches in an audio signal. For a
first approach, the obtained results are very
promising: our error rate outperforms two of three
state-of-the-art pitch estimators.",
