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.

Abstract: The present technique relates to an encoding device and a method, a decoding device and a method, and a program capable of obtaining higher quality audio. An encoding unit encodes position information and a gain of an object in a current frame in multiple encoding modes. A compressing unit generates, for each combination of encoding modes of each pieces of position information and gains, encoded meta data including encoding mode information indicating the encoding modes and encoded data which are the encoded position information and gains, and compresses the encoding mode information included in the encoding meta data. A determining unit selects encoded meta data of which amount of data is the least from among the encoded meta data generated for each combination, thus determining the encoding mode of each pieces of position information and gains. The present technique can be applied to an encoder and a decoder.
