摘要：It is possible to provide an encoding device and an encoding method capable ofrealizing encoding with a very small information amount and a very small calculationamount when encoding higher-band spectrum data according to lower-band spectrum
data in a wide-band signal . The device and the method can obtain a high-quality decodedsignal even if a large quantization distortion is caused in the lower-band spectrum data. Inthis device, when encoding higher-band spectrum data in a signal to be encoded,according to lower-band spectrum data in the signal, only for a part (a head portion) ofthe higher-band spectrum data, the lower-band spectrum data after being quantized issubjected to approximate partial search and higher-band spectrum data is generatedaccording to the search result.
