摘要： Encoding and/or decoding a wideband signal produces high frequency band spectra from low frequency band spectral information. Linear prediction filter coefficients are determined for the entire wideband spectrum of an input signal. An energy value in each of a plurality of sub-bands in the high frequency band is determined and encoded. The short-term correlation removed input signal is then down-sampled to form a low frequency band signal. At a decoder, the high frequency band signal is generated using the encoded low frequency band signal. The energy in each sub-band of the high frequency band is adjusted using the encoded energy value. Thus, the spectral envelope for the entire wideband signal is synthesized and decoded using linear predictive synthesis.

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.
