Binaural reverberators often use a tapped delay line to model early reflections, to which a delayed late reverberation tail is added. This paper introduces a reverberator structure where the early reflections are modeled using a feedback delay network (FDN) and the late reverberation is modeled by a second FDN in parallel. The impulse responses of both FDNs are highly overlapping, simulating the presence of diffuse reverberation from the beginning of the impulse response. A particular feature of this reverberator is the reproduction of first and second order reflections using only head related transfer functions (HRTFs) for the directions of the first order reflections, allowing to reduce the computational complexity.
