Auralization in room acoustics is created by the convolution of an anechoic audio signal with the RIR (room impulse response), either computed or measured at the receiver location. This paper addresses the directional RIRs computed by ray tracing and presents a technique to improve the directionality of the DRIR (directional room impulse response) introduced in . This improvement consists in providing each component of the direct sound and first reflections (up to a given order) separately of directional late reverberation which is still computed as in .
