Abstract:
The present technology relates to an encoding device and a method, a decoding device and a method, and a program that enables acquisitions of high-quality sound even in a resource-poor setting. A demultiplexer demultiplexes a supplied code string, to obtain the quantized low-band spectrum, the spectral characteristic code, and the quantized expansion coefficient(s). At this point, the code string includes a single quantized expansion coefficient or quantized expansion coefficients of the respective bands in the high band depending on the spectral characteristic code. A spectral inverse quantization unit obtains the low-band spectrum by inversely quantizing the quantized low-band spectrum. An expansion coefficient inverse quantization unit obtains the expansion coefficient(s) by inversely quantizing the quantized expansion coefficient(s). An expanded spectrum generation unit generates an expanded spectrum, in accordance with the low-band spectrum and the expansion coefficient(s) depending on the spectral characteristic code. An IMDCT unit generates a band-expanded time-series signal from the low-band spectrum and the expanded spectrum. The present technology can be applied to decoding devices.

Claim (Index 7):
A non-transitory computer-readable medium containing computer-executable instructions that, when executed by a processing device, perform a process,\n the process comprising: acquiring a low-band spectrum, and a single expansion coefficient of an expanded band or a plurality of expansion coefficients of respective bands constituting the expanded band, the expanded band being different from a low band, the single expansion coefficient or the plurality of expansion coefficients being for obtaining an expanded spectrum of the expanded band; generating the expanded spectrum by adjusting a level of a seed spectrum or a random noise in accordance with the expansion coefficients or envelope coefficients corresponding to spectral characteristics; and combining the low-band spectrum and the expanded spectrum.
