    • Disclosed are an audio apparatus and an audio providing method thereof. The audio providing method includes receiving an audio signal including a plurality of channels, applying an audio signal having a channel, from among the plurality of channels, giving a sense of elevation to a filter to generate a plurality of virtual audio signals to be respectively output to a plurality of speakers, applying a combination gain value and a delay value to the plurality of virtual audio signals so that the plurality of virtual audio signals respectively output through the plurality of speakers form a sound field having a plane wave, and respectively outputting the plurality of virtual audio signals, to which the combination gain value and the delay value are applied, through the plurality of speakers. The filter processes the audio signal to have a sense of elevation.

    • In cases of rendering a multichannel signal such as a 22.2 channel signal as a 5.1 channel signal, a three dimensional (3D) audio signal may be reproduced using a two dimensional (2D) output channel, but rendered audio signals are sensitively affected by a layout of speakers and may cause distortion of a sound image when the layout of arranged speakers is different from a standard layout.
      The present invention may solve the aforementioned problem of the prior art. The audio signal rendering method for reducing distortion of a sound image even when the layout of the arranged speakers is different from the standard layout, according to one embodiment of the present invention, includes: receiving a multi-channel signal including a plurality of input channels that are to be converted to a plurality of output channels; obtaining deviation information about at least one output channel, from a location of a speaker and a standard location corresponding to each of the plurality of output channels; and modifying a panning gain from a height channel included in the plurality of input channels to the output channel having the deviation information, based on obtained deviation information.
    • 在渲染的多声道信号的情况下:例如作为5.1声道信号,一个三维(3D)音频信号可使用二维(2D)输出通道被再现,但呈现的音频信号中的22.2信道信号是敏感的影响的布局 扬声器的,并且可能导致声音图像的失真当布置扬声器的布局是从标准布局不同。 本发明可以解决上述问题的现有技术。 用于减少一个声音图像的失真即使当布置扬声器的布局是从标准布局,雅鼎在本发明一个实施例,不同的音频信号渲染方法,包括:接收多通道信号包括输入信道与多个 没有被转换为输出信道与多个; 获得关于至少一个输出通道偏差信息,从一个扬声器和一个标准的位置对应于每个输出信道的多个的位置; 和包括在输入信道的多元性到具有偏差信息的输出通道修改从一个高度信道摇摄增益,基于偏差获得的信息。
