Supplementary data for: A Low-Dimensional Projection of Sound Absorption Coefficients for a Scattering Delay Network Reverberator

Supplementary research data to the paper (under review): Marco Fontana, Davide Fantini, Giorgio Presti, Marco Tiraboschi, and Federico Avanzini. A Low-Dimensional Projection of Sound Absorption Coefficients for a Scattering Delay Network Reverberator. Submitted to the Journal of the Audio Engineering Society. December 2024. The repository provides additional research data for the paper. In particular, the repository includes: README.md: instructions for the data 2d_parameter_space.rar: additional data for the proposed 2D parameter space (2PS) obtained by the dimensionality reduction of an absorption coefficients dataset. reverb_matching.rar: detailed results of the reverb matching method for the estimation of absorption coefficients. These results include the comparison between the target and estimated absorption coefficients, the generated SRIRs, and the corresponding acoustic features. usability_test.rar: additional data for the usability test, including the target sets of absorption coefficients and the questionnaires submitted to the users. The paper builds upon an implementation of a Scattering Delay Network (SDN), which is available here.
