Abstract
This paper investigates the effect of the grid resolution of binaural room acoustic auralization on spatial and timbral fidelity. Binaural concert hall stimuli were generated using a virtual acoustics program utilizing image source and ray tracing techniques. Each image source and ray were binaurally synthesized using Lebedev grids of increasing resolution from 6 to 5810 (reference) points. A MUSHRA test was performed where subjects rated the magnitudes of spatial and timbral differences of each stimulus to the reference. Overall, it was found that on the MUSHRA scale, 6 points were perceived to be "Fair," 14 points "Good," and 26 points and above all "Excellent" on the grading scale, for both spatial and timbral fidelity.
