Spatial room response rendering is a recent technique to reproduce the acoustics of an enclosed space in a spatial form. In this technique the original sound field is not precisely reproduced but based on psychoacoustics concepts for human localization and physics of sound, the originalsound field is analyzed, and a kind of sound field is synthesized that is perceptually correspondedto the original one. To reach this goal, the room response is first measured and then desired responseis synthesized. In this method, the loudspeaker system is not limited to a specific structureand any loudspeaker setup can be used for reproduction.In this paper, we report the results of applying spatial room response rendering technique to measured data of a room. In this work, an Exponential Sine Sweep (ESS) was used as excitation signal that ranges all audio frequencies, B–format microphone technique was used for the firsttime for room response measurement, and reproduction setup is based on three full band loudspeakersassembly. Time dependency of arrival direction and diffuseness of the measured room responses are analyzed and based on the results of this analysis, a multichannel response is synthesized for the loudspeaker setup<\div>
