摘要： There is provided a coding technique capable of reducing the amount of computation in coding while maintaining the efficiency of the coding. The technique uses an input signal and one of a decoded signal decoded from a first code obtained by encoding the input signal and a decoded signal obtained during generation of the first code. A gain group set includes one or more gain groups including different numbers of values corresponding to gains. A gain group is allocated to each sample by using a predetermined method. The sample is multiplied by a gain identified by a value corresponding to each gain in the allocated gain group and a gain code indicating a gain that results in the smallest difference between the product and the input signal is output.

摘要： A quantized normalization value and a normalization-value quantization index corresponding to the quantized normalization value are obtained, the quantized normalization value being obtained by quantizing a normalization value that is a value representative of samples. If a difference value that is obtained by subtracting a value corresponding to the quantized normalization value from a value corresponding to a magnitude of a value of each sample is positive and if the value of each sample is positive, the difference value is set as a quantization candidate. If the difference value is positive and if the value of each sample is negative, a value obtained by inverting positive/negative of the difference value is set as the quantization candidate. The plurality of quantization candidates respectively corresponding to the plurality of samples are collectively vector-quantized, and a vector quantization index is thus obtained and output. Sign information is output, the sign information expressing positive/negative of each sample that does not make the difference value positive, among the samples. Accordingly, encoding and decoding techniques capable of reducing musical noise and the like can be provided.
