M. R. Schroeder’s scientific contributions

... Some authors [48,49] combined acoustic radiance transfer with path tracing to account for diffuse reflections (and edge diffraction) in interactive acoustic environments, both generating impulse responses and using convolution and interpolation. In [49], late reverberation is separately implemented using a Schroeder-type artificial reverberator [50]. Sound scattering at surfaces is considered in scattering delay networks (SDNs; [51,52]), which combine principles of GA and digital waveguide networks (to efficiently account for late reverberation, similar to FDNs). ...
