Audio signal reproducing method and an apparatus for reproducing the same

Abstract

A method of reproducing audio signals comprises: transforming audio signals into a plurality of frequency components; seeking the plurality of the frequency components for a reference frequency component domain; attenuating power of at least one of reference components in the reference frequency component domain to interpolate the frequency component in a frequency band higher than the reference frequency component domain, and transforming the interpolated frequency component into a time component. And an apparatus of reproducing audio signals comprising: a frequency component decoder configured to decode audio signals into frequency components; a frequency component domain seeking unit configured to seek the frequency components for a reference frequency component domain that is to be interpolated in a high frequency band; a reference frequency component extractor configured to extract a reference frequency component from the reference frequency component domain; a frequency component power transforming unit configured to attenuate power of the reference frequency component for producing a frequency component that is to be interpolated, and an inverter configured to transform the interpolated frequency component into a time component.
