    摘要: Provided is a method and apparatus for encoding/decoding an audio signal. Sections which are not used to output noise components near important spectral components and sub-bands which are not used to output noise components, are determined to be encoded or decoded, so that the efficiency of encoding and decoding an audio signal increases, and sound quality can be improved using less bits.

    摘要: A method and apparatus to encode and decode an audio signal. In the encoding method and apparatus, one or more important frequency components may be detected from an audio signal, the frequency components may be encoded, and then an envelope of the audio signal may be encoded. In the decoding method and apparatus, an audio signal may be decoded by adjusting envelopes at one or more bands containing one or more important frequency components in consideration of the energy values of the frequency components. Accordingly, it is possible to maximize the coding efficiency without degrading the sound quality of the audio signal even if the audio signal is encoded or decoded using a small amount of bits.
