Audio apparatus, method of processing audio signal, and a computer-readable recording medium storing program for performing the method

An audio apparatus comprising:

• an input device to receive a main audio and an interactive audio;
• a panning device to pan the interactive audio by using position information of a user, position information of a sound source of the interactive audio, and speaker position information;
• a renderer to render the panned interactive audio according to a space characteristic of the main audio;
• and
• an output device to mix and output the rendered interactive audio and the main audio.

An audio apparatus comprising:

• a panning device to pan interactive audio in a three dimensional (3D) space using relative position information of a sound source and a panning coefficient table based on a user position;
• a renderer device to render the panned interactive audio by using space information of a main audio;
• and
• an output device to mix and output the rendered interactive audio and the main audio.
