A Fully Convolutional Deep Auditory Model for Musical Chord Recognition
Chord recognition systems depend on robust feature extraction pipelines.
While these pipelines are traditionally hand-crafted, recent advances in
end-to-end machine learning have begun to inspire researchers to explore
data-driven methods for such tasks. In this paper, we present a chord
recognition system that uses a fully convolutional deep auditory model for
feature extraction. The extracted features are processed by a Conditional
Random Field that decodes the final chord sequence. Both processing stages are
trained automatically and do not require expert knowledge for optimising
parameters. We show that the learned auditory system extracts musically
interpretable features, and that the proposed chord recognition system achieves
results on par or better than state-of-the-art algorithms.Comment: In Proceedings of the 2016 IEEE 26th International Workshop on
