Audio apparatus and method of converting audio signal thereof

摘要

An audio apparatus and a method of converting an audio signal are provided. The method includes: receiving a first audio signal including a plurality of channels (S810); comparing audio signals of the plurality of channels to estimate a source position of the first audio signal (S830); localizing a source of the first audio signal toward a three-dimensional (3D) position having an elevation component based on the estimated source position (S840); converting the first audio signal into a second audio signal including the plurality of channels and at least one channel having, based on the localized source, a different elevation from the plurality of channels (S850); and outputting the second audio signal (S860).
