signal processing systems for the reproduction of audio data on virtual loudspeaker arrays

摘要

electronic device that is configured in a left loudspeaker and a right ear of a human listener to reproducewith the loudspeaker of a variety of virtual loudspeakers are generated, and the electronic device includes: a memory; and memory related steuerschaltungen,with the steuerschaltungen are configured for the following: a sound reproduction, prozessorschaltungen computer which is configuredthe loudspeaker in the left and the right ear of the head of the human listener to reproduce a variety of external ear - impulse responses. these (hrirs)each of the large number of hrirs with a virtual speaker from the variety of virtual speakers and one ear of the human listener is associatedeach of the large number of hrirs samples of klangfelds includes, at a specific samplingrate in a left or right ear is producedin response to a audioimpuls is generated of the virtual speaker is produced; creating a first zustandsraumdarstellung each by the number of hrirs,with the first zustandsraumdarstellung a matrix, a spaltenvektor and a row vector includes, using both the matrix and the spaltenvektor,and the row vector of the first zustandsraumdarstellung a first size; performing a zustandsraum - cannot accurately be passed.a second zustandsraumdarstellung each by the number of hrirs to produce, with the second zustandsraumdarstellung a matrix, a spaltenvektor and a row vector includesusing both the matrix and the spaltenvektor and the row vector of the second zustandsraumdarstellung a second size.the lower than a first size; underzeugen a variety of auu00dfenohru00fcbertragungsfunktionen (hrtfs) based on the second zustandsraumdarstellung,each of the large number of hrtfs a respective hrir from the variety of hrirs corresponding to a hrtf a respective hrir corresponds to theas soon as you with a frequency range - sound field is multiplied by the virtual speakers, is generated with the corresponding hrir is associateda component of a klangfelds produces in the ear of the human listener is rendered.
