    • PROBLEM TO BE SOLVED: To provide a device and a method for reproducing a multichannel audio signal by using only two speakers. SOLUTION: The device is equipped with a data restoration part 40 which restores multichannel audio data of a frequency range by decoding a received multichannel audio signal, a directivity storage processing part 45 which outputs left and right main-channel audio data holding directivity, by mixing with audio data of the left and right main channels audio data of a center and stereo surround channels obtained, by multiplying the audio signals of the center and stereo surround channels using by a head-related transfer function representing frequency variation characteristics, based upon the head of the listener by a function, and a processing area conversion part 50, which converts the left and right main-channel audio data after directivity holding processing into data of a time area.
    • 要解决的问题:提供通过仅使用两个扬声器再现多声道音频信号的装置和方法。 解决方案:该装置配备有数据恢复部分40,其通过解码接收的多声道音频信号来恢复频率范围的多声道音频数据;方向性存储处理部分45,其通过混合输出左和右主声道音频数据保持方向性 通过利用表示频率变化特性的与头相关的传递函数乘以中心和立体声环绕声道的音频信号,获得中心和立体声环绕声道的左和右主要声道音频数据的音频数据,基于头部 以及处理区转换部50,其将方向性保持处理之后的左右主声道音频数据转换为时区的数据。
