Abstract:
An audio apparatus and an audio providing method thereof are provided. 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.

Claim (Index 1):
A method of rendering an audio signal, the method comprising:\n receiving a plurality of input channel signals including a height input channel signal; identifying an output layout of two dimensions, wherein the output layout is formed of a plurality of output channel signals; obtaining a type of filter based on a position of the height input channel signal; obtaining a set of panning gains based on a frequency range and the position of the height input channel signal; and generating the plurality of output channel signals by elevation rendering the plurality of input channel signals, based on the type of filter and the set of panning gains, to provide elevated sound images, wherein the position of the height input channel signal comprises elevation information and azimuth information, and wherein the set of panning gains is comprised a first group or a second group according to the frequency range.
