Method and apparatus for applying waveform prediction to subbands of a perceptual coding system |
摘要 |
A split-band perceptual coding system utilizes generalized waveform predictive coding in frequency bands to further reduce coded signal information requirements. The system including frequency subband each having a bandwidth commensurate with or less than a corresponding critical band of human perception. The order of the predictors are selected to balance requirements for prediction accuracy and rapid response time. Predictive coding may be adaptively inhibited in a band during intervals in which no predictive coding gain is realized. |
