Abstract:
1. A method for generating a sideband residual signal comprising: obtaining a quantized value (CLD_Q) of a stereophonic parameter (CLD); comparing energy of a first signal input by a first sound channel with energy of a second signal input by a second sound channel by determining whether the CLD_Q is greater than or less than one; generating the sideband residual signal by allocating a monophonic quantization error to the first signal when the CLD_Q is greater than one and the energy of the first signal is greater than the energy of the second signal; and generating the sideband residual signal by allocating the monophonic quantization error to the second signal when the CLD_Q is less than one and the energy of the first signal is smaller than the energy of the second signal.
