Signed Wasserstein distance for room impulse response comparison
Linda Fabiani, Sebastian J. Schlecht, Filip Elvander
The nature of room impulse response signals is often adverse to a clear evaluation of similarity: they are sparse, rapidly varying, signed signals resulting from the complex intera…

pyFDN: A Python Toolbox for Feedback Delay Network Design, Analysis, and Optimization
Sebastian J. Schlecht, Facundo Franchino, Jeremy B. Bai
Feedback delay networks (FDNs) provide a compact representation of recursive audio systems for artificial reverberation and decorrelation. Their practical use spans structured matr…

Joint Estimation of Common-Slope Decay Rates and Spatial Amplitudes Using Parameterized Nonnegative Matrix Factorization
Jeremy B. Bai, Filip Elvander, Sebastian J. Schlecht
We formulate joint estimation of common-slope decay rates and amplitudes from room impulse responses (RIRs) as parameterized nonnegative matrix factorization with the Itakura--Sait…
