Bit-Weighted Inter-Channel Prediction for Subband Audio Coding
An efficient algorithm for removing inter-channel redundancy in subband audio coding is presented in this paper. In our approach, the bit-weighted inter-channel prediction is applied to the Modified Discrete Cosine Transform (MDCT) coefficients. Similar to the INT-DCT based approach, no audio quality degradation will be induced by our method. In addition, the bit rate reduction performance of our method is about 8% better than that of the INT-DCT based approach for the cases that inter-channel prediction is useful.
