GFDNs connect multiple spaces with different T60 characteristics and a parameterized mixing matrix to control inter- and intra-group coupling. In this plugin, 2 coupled rooms are implemented with the GFDN. For more details, see
- Delay Network Architectures for Room and Coupled Space Modeling - Das et al. in Proc. of International Conference on Digital Audio Effects, DAFx 2020.
- Grouped Feedback Delay Networks for Modeling of Coupled Spaces - Das and Abel, Journal of the Audio Engineering Society, JAES 2021.
The plugin now simulates diffraction through the aperture connecting the two rooms by adding filters to the mixing matrix.
