Helicality: An Isomap-based Measure of Octave Equivalence in Audio Data
Sripathi Sridhar, Vincent Lostanlen
Octave equivalence serves as domain-knowledge in MIR systems, including chromagram, spiral convolutional networks, and harmonic CQT. Prior work has applied the Isomap manifold lear…

Learning the helix topology of musical pitch
Vincent Lostanlen, Sripathi Sridhar, Brian McFee +2
To explain the consonance of octaves, music psychologists represent pitch as a helix where azimuth and axial coordinate correspond to pitch class and pitch height respectively. Thi…
