AUDIO REPRODUCING APPARATUS AND METHOD |
摘要 |
An audio reproducing apparatus includes: an obtainment unit configured to obtain a stereo audio signal including an L channel signal and an R channel signal; and a control unit configured to (i) generate a first audio signal for a speaker disposed at an upper position in a listening space and a second audio signal for a speaker disposed at a lower position in the listening space, using the L channel signal and the R channel signal and (ii) determine a gain coefficient corresponding to a degree of correlation between the L channel signal and the R channel signal and multiply by the determined gain coefficient at least one of the first audio signal and the second audio signal, to approximate a ratio between energy of sound reproduced from the first audio signal and energy of sound reproduced from the second audio signal to a predetermined value. |

1. An audio reproducing apparatus, comprising:
an obtainment unit configured to obtain a stereo audio signal including an L channel signal and an R channel signal; and a control unit configured to (i) generate a first audio signal for a speaker disposed at an upper position in a listening space and a second audio signal for a speaker disposed at a lower position in the listening space, using the L channel signal and the R channel signal and (ii) determine a gain coefficient based on the L channel signal, the R channel signal, and a degree of correlation between the L channel signal and the R channel signal and multiply by the determined gain coefficient at least one of the first audio signal and the second audio signal, to approximate a ratio between energy of sound reproduced from the first audio signal and energy of sound reproduced from the second audio signal to a predetermined value, wherein the control unit is configured to generate at least one of the first audio signal and the second audio signal by combining the L channel signal and the R channel signal. |
