Abstract
An encoding device includes a control circuit which, when it has been determined that an input stereo signal is suitable to be encoded using a mid-side stereo technique, decides, according to a condition, whether to convert the input stereo signal into a mid-side signal in a time domain and apply first encoding or apply second encoding; a first encoding circuit that encodes the mid-side signal when the first encoding is to be applied; and a second encoding circuit that encodes the input stereo signal in a frequency domain when the second encoding is to be applied.
