    • An apparatus for processing an audio signal and method thereof are disclosed. The present invention includes receiving a spectral data of lower band and type information indicating a particular band extension scheme for a current frame of the audio signal from among a plurality of band extension schemes including a first band extension scheme and a second band extension scheme, by an audio processing apparatus; when the type information indicates the first band extension scheme for the current frame, generating a spectral data of higher band in the current frame using the spectral data of lower band by performing the first band extension scheme; and when the type information indicates the second band extension scheme for the current frame, generating the spectral data of higher band in the current frame using the spectral data of lower band by performing the second band extension scheme, wherein the first band extension scheme is based on a first data area of the spectral data of lower band, and wherein the second band extension scheme is based on a second data area of the spectral data of lower band.
    • 公开了一种用于处理音频信号的装置及其方法。 本发明包括从包括第一频带扩展方案和第二频带扩展方案在内的多个频带扩展方案中接收指示用于音频信号的当前帧的特定频带扩展方案的较低频带的频谱数据和类型信息,由 音频处理装置; 当类型信息指示当前帧的第一频带扩展方案时,通过执行第一频带扩展方案,使用较低频带的频谱数据在当前帧中产生较高频带的频谱数据; 并且当类型信息指示当前帧的第二频带扩展方案时,通过执行第二频带扩展方案,使用较低频带的频谱数据生成当前帧中较高频带的频谱数据,其中第一频带扩展方案基于 在较低频带的频谱数据的第一数据区上,并且其中第二频带扩展方案基于较低频带的频谱数据的第二数据区。
