abstract = "This paper presents a new method with a set of
desirable properties for multi-pitch estimation of
piano recordings. We propose a framework based on a set
of classifiers to analyse audio input and to identify
piano notes present in a given audio signal. Our
system's classifiers are evolved using Cartesian
genetic programming: we take advantage of Cartesian
genetic programming to evolve a set of mathematical
functions that act as independent classifiers for piano
notes. Two significant improvements are described: the
use of a harmonic mask for better fitness values and a
data augmentation process for improving the training
stage. The proposed approach achieves competitive
results using F-measure metrics when compared to
state-of-the-art algorithms. Then, we go beyond piano
and show how it can be directly applied to other
musical instruments, achieving even better results. Our
system's architecture is also described to show the
feasibility of its parallelization and its
implementation as a real-time system. Our methodology
is also a white-box optimisation approach that allows
for clear analysis of the solutions found and for
researchers to learn and test improvements based on the
new findings.",
