Modulation Discovery with Differentiable Digital Signal Processing

This week I’ll be at @waspaa.com presenting our work on discovering synthesizer modulation signals in arbitrary audio.

Lol the Nobels can't even acknowledge women's contribution to discovery. But sure let's acknowledge The Machines.

Headline from an article in Nature this week that states "Prizes must recognize machine contributions to discovery. The future of science will be written by humans and machines together. Awards should reflect that reality."

written with PhD student Yuexuan Kong and her advisors, both at @researchdeezer.bsky.social (G. Meseguer-Brocal, R. Hennequin), and @cnrs.fr (M. Lagrange)

+ special thanks to @ethanhein.bsky.social for this insightful blog post, which we credit in Section II

We also prove that STONE induces spontaneous symmetry breaking, since modes of limited transposition (e.g., augmented, diminished, whole-tone) are multistable in the circle of fifths, the associated CPSD gradient is driven towards more "tonal" (i.e., asymmetric) scales, e.g., diatonic or pentatonic.

Vincent Lostanlen @lostanlen.bsky.social · 6d

Our main result. If the frequency of cross-power spectral density is set to be coprime with Q=12, STONE does not collapse: the self-supervised objective is well-posed and sparsity-inducing in pitch class space.

Vincent Lostanlen @lostanlen.bsky.social · 6d

"Understanding equivariant self-supervised learning in musical pitch class space" is out on IEEE Signal Processing Letters!

in which we revisit STONE (Kong et al., ISMIR 2024) from a more theoretical standpoint
