    Abstract: An audio processing apparatus may obtain second audio signals corresponding to channels included in a second channel group from first audio signals corresponding to channels included in a first channel group, downsample at least one third audio signal corresponding to at least one channel identified based on a correlation with the second channel group from among the channels included in the first channel group, by using an artificial intelligence (AI) model, and generate a bitstream including the second audio signals corresponding to the channels included in the second channel group and the downsampled at least one third audio signal. The first channel group includes a channel group of an original audio signal, and the second channel group is constructed by combining at least two channels from among the channels included in the first channel group.

    Abstract: An apparatus for outputting an audio signal includes: a channel processor configured to generate two or more channel signals from audio data; a signal processor configured to render the generated two or more channel signals; and a directional speaker configured to reproduced a rendered channel signal as an audible sound. The signal processor may include a frequency converter configured to generate a channel signal of a frequency domain by converting the generated two or more channel signals through frequency conversion, and a re-panner configured to change a channel gain of at least one of the generated channel signals by as much as an adjustment value for the channel gain, wherein the adjustment value is monotonically changed as a frequency of the channel signal of the frequency domain increases.
