  • Audio decoding method and apparatus for reconstructing high frequency components with less computation
    Patent number: 7444289
    Abstract: An audio decoding method and apparatus for reconstructing high frequency components with less computation are provided. The audio decoding apparatus includes a decoder, a channel similarity determination unit, a high frequency component generation unit, and an audio synthesizing unit. The audio decoding method generates high frequency components of frames while skipping every other frame for each channel signal; when right and left channel signals are similar to each other, generates high frequency components of the skipped frame for any one channel signal by using the generated high frequency components of the corresponding frame for the other channel signal; and when the right and left channel signals are not similar to each other, generates high frequency components of the skipped frames for each channel signal by using previous frames for the relevant channel signal.
