Abstract: The present technique relates to a frequency band extension apparatus, a frequency band extension method, and a program which are configured to more easily obtain a high quality sound signal. An input signal may be divided into sub-band signals of a plurality of sub-bands, powers of high frequency sub-bands of the input signal may be estimated based on feature values extracted from the input signal to obtain high frequency sub-band power estimation values, the high frequency sub-band powers obtained from the sub-band signals of high-frequency sub-bands of the input signal may be compared with the high frequency sub-band power estimation values, and a high-frequency signal of the input signal may be generated based on a result of the comparison and the sub-band signals.

Abstract: The present technology relates to an encoding device and method, a decoding device and method, and a program therefor capable of improving audio signal transmission efficiency.An identification information generation unit determines whether or not an audio signal is to be encoded on the basis of the audio signal, and generates identification information indicating the determination result. An encoding unit encodes only audio signals determined to be encoded. A packing unit generates a bit stream containing the identification information and encoded audio signals. As a result of storing only encoded audio signals in the bit stream and storing the identification information indicating whether or not the respective audio signals are to be encoded in the bit stream in this manner, the transmission efficiency of audio signals can be improved. The present technology can be applied to an encoder and a decoder.
