Recirculationless concert hall simulation and enhancement system

摘要

A recirculationless concert hall simulation and enhancement system includes a reproduction system having a primary loudspeaker driven from a signal source and a number of auxiliary loudspeakers driven by sequentially delayed replicas of the original signal so as to reproduce the ambience associated with large size concert halls in a considerably smaller listening room without tonal discoloration. In a preferred embodiment total cumulative sequential delays exceed 50 milliseconds to give enhanced ambience, while individual inter-speaker delays are limited to less than 50 milliseconds, so that distinguishable, distinct echoes are not generated.
