Abstract

본 발명은 보다 효율적인 음장을 생성할 수 있는 음장재생장치에 관한 것이다. 본 발명의 장치는 디지탈 음향신호를 입력받기 위한 입력수단과, 입력되는 디지탈 음향신호의 샘플링주파수레이트를 제어하는 제어수단과, 제어수단의 제어에 따라 입력되는 디지탈 음향신호 중 특정위치에 해당하는 음향신호만을 저장하는 메모리와, 입력되는 디지탈 음향신호와 메모리에 저장된 디지탈 음향신호를 조합하여 원하는 음장의 음향신호를 생성하는 디지탈신호처리부, 및 생성된 음장의 음향신호를 청취가능한 형태로 출력하는 출력수단으로 구성된다.The present invention relates to a sound field reproducing apparatus capable of generating a more efficient sound field. The apparatus of the present invention comprises an input means for receiving a digital sound signal, a control means for controlling a sampling frequency rate of the input digital sound signal, and a sound corresponding to a specific position among the digital sound signals input under the control of the control means. A digital signal processor for generating a sound signal of a desired sound field by combining a memory for storing only a signal, an input digital sound signal and a digital sound signal stored in the memory, and output means for outputting the generated sound signal in an audible form. It consists of.

따라서, 본 발명은 음장생성에 필요한 메모리의 용량을 줄일 수 있는 효과를 제공한다.Therefore, the present invention provides an effect of reducing the capacity of the memory required for sound field generation.
