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.
