A Compact Spherical Loudspeaker Array for Efficiently Recreating Instrument Directivities

Document Thumbnail

High levels of realism can be achieved using measurement-based auralizations of concert halls, but typical measurement loudspeakers limit source realism. A compact spherical loudspeaker array was designed to reconstruct the frequency-dependent radiation patterns of different orchestral instruments. A filter bank for each instrument was designed to preprocess measurement signals with built-in source radiation patterns for room impulse response measurements.
