This paper introduces a reverberator structure where the early reections aremodeled using a feedback delay network (FDN) and the late reverberation is modeled by a second FDNin parallel. The impulse responses of both FDNs are highly overlapping, simulating the presence of di usereverberation from the beginning of the impulse response. A particular feature of this reverberator is thereproduction of rst and second order reections using only head related transfer functions (HRTFs) for thedirections of the rst order reections, allowing to reduce the computational complexity.
