Abstract

Audio files for an audio piece are stored in cross-scene optimized manner, so that when reading out audio files for a scene entailing high utilization of a wave field synthesis system, very short memory access times are achieved, whereas for scenes not entailing such a high utilization of the wave field synthesis system, longer memory access times in turn are accepted.
