摘要： Provided is a method and apparatus for encoding or decoding a signal corresponding to a high frequency band in an audio signal. The method and apparatus for encoding a high frequency band detects and encodes frequency component(s) according to a pre-set criterion from a signal corresponding to a frequency band higher than a pre-set frequency and encodes energy value(s) of a signal to reconstruct band(s) in which the detected frequency component(s) are included. The method and apparatus for decoding a high frequency band decodes the signal by adjusting a signal to reconstruct a band in which important frequency component(s) are included by considering an energy value of the important frequency component(s). Accordingly, even though encoding or decoding is performed using a small number of bits, there is no degradation in sound quality of a signal corresponding to a high frequency band, and thus coding efficiency can be maximized.

The high frequency signal can be encoded by extracting a coefficient by linear predicting a high frequency signal, and encoding the coefficient, generating a signal by using the extracted coefficient and a low frequency signal, and encoding the high frequency signal by calculating a ratio between the high frequency signal and an energy value of the generated signal. Also, the high frequency signal can be decoded by decoding a coefficient, which is extracted by linear predicting a high frequency signal, and a low frequency signal, and generating a signal by using the decoded coefficient and the decoded low frequency signal, and adjusting the generated signal by decoding a ratio between the generated signal and an energy value of the high frequency signal.
