APPARATUS AND METHOD FOR GENERATING FILTER CHARACTERISTICS |
摘要 |
<p>An apparatus for generating filter characteristics for filters connectible to at least three loudspeakers at defined locations with respect to a sound reproduction zone comprises an impulse response reverser (10) for time-reversing impulse responses associated to the loudspeakers to obtain time-reversed impulse responses. The apparatus furthermore comprises an impulse response modifier (14) for modifying the impulse responses or the time-reversed impulse responses such that impulse response portions occurring before a maximum of a time-reversed impulse response are reduced in amplitude to obtain the filter characteristics for the filters.</p> |
