All-pole centroids in the Wasserstein metric with applications to clustering of spectral densities
Rumeshika Pallewela, Filip Elvander
In this work, we propose a method for computing centroids, or barycenters, in the spectral Wasserstein-2 metric for sets of power spectral densities, where the barycenters are rest…

Inverse harmonic clustering for multi-pitch estimation: an optimal transport approach
Anton Björkman, Filip Elvander
In this work, we consider the problem of multi-pitch estimation, i.e., identifying super-imposed truncated harmonic series from noisy measurements. We phrase this as recovering a h…

A Diffusion-Based Generative Equalizer for Music Restoration
Eloi Moliner, Maija Turunen, Filip Elvander +1
This paper presents a novel approach to audio restoration, focusing on the enhancement of low-quality music recordings, and in particular historical ones. Building upon a previous…
