Abstract: A method of encoding stereo audio that minimizes a number of pieces of side information required for parametric-encoding and parametric-decoding of the stereo audio. The side information may include parameters about interchannel intensity difference (IID), interchannel correlation (IC), overall phase difference (OPD), and interchannel phase difference (IPD), which are required to restore the mono audio to the stereo audio.

Abstract: An audio encoding method and apparatus, and an audio decoding method and apparatus, for processing a death sinusoid and a general continuation sinusoid. Using the unique characteristic of a death sinusoid, in that the death sinusoid has a tendency such that an amplitude component of the death sinusoid is less than that of a previous sinusoid, a method of adding an encoding syntax by distinguishing a general continuation sinusoid from a death sinusoid is provided. That is, when difference coding of the amplitude component of a death sinusoid is performed, the number of bits used when a negative number is coded is less than the number of bits used when a positive number is coded, in a Huffman table. By using this method, a bit rate in an entire coding decreases.
