Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for performing residual quantization are described. One example of the methods includes performing a first residual quantization on a first target residual signal at a first bit rate to generate a first quantized residual signal. A second target residual signal is generated based at least on the first quantized residual signal and the first target residual signal. A second residual quantization is performed on the second target residual signal at a second bit rate to generate a second quantized residual signal, where the first bit rate is different from the second bit rate.
