The output selection unit supplies the MDCT coefficient to an IMDCT unit in the case where the priority degree indicated in the priority information is more than or equal to a predetermined degree, and supplies 0 as the MDCT coefficient to a 0-value output unit in the case where the priority degree is less than the predetermined degree. The 0-value output unit generates an audio signal on the basis of 0 supplied as the MDCT coefficient. In addition, the IMDCT unit performs IMDCT on the basis of the MDCT coefficient to generate an audio signal. The present technology can be applied to an encoder and a decoder.
