Abstract
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; comparing audio signals of the plurality of channels to estimate a source position of the first audio signal; localizing a source of the first audio signal toward a three-dimensional (3D) position having an elevation component based on the estimated source position; 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; and outputting the second audio signal.

A method of converting an audio signal of an audio apparatus, the method comprising:
- receiving a first audio signal comprising a plurality of channels;
- comparing audio signals of the plurality of channels to estimate a source position of the first audio signal;
- localizing a source of the first audio signal toward a three-dimensional (3D) position having an elevation component based on the estimated source position;
- converting the first audio signal into a second audio signal comprising the plurality of channels and at least one channel having, based on the localized source, a different elevation from the plurality of channels;
- and
- outputting the second audio signal.
An audio apparatus comprising:
- a receiver which receives a first audio signal comprising a plurality of channels;
- a source position estimator which compares audio signals of the plurality of channels to estimate of a source position of the first audio signal;
- an audio signal converter which localizes a source of the first audio signal toward a three-dimensional (3D) position having an elevation component based on the estimated source position, and converts the first audio signal into a second audio signal comprising the plurality of channels and at least one channel having, based on the localized source, a different elevation from the plurality of channels;
- and
- an output part which outputs the second audio signal.
