Subjective comparisons of room acoustics require high-fidelity auralizations. Earlier
research has shown that room impulse response measurements and directional analysis
with the Spatial decomposition method provides accurate reproductions of concert hall
acoustics in multi-channel listening. Moreover, timbral aspects have been found important
for the overall audio quality, even more than spatial fidelity. This paper explores the effect by
the number of true and virtual loudspeakers, and application of amplitude panning, to …
