Abstract
An encoding method and apparatus and a decoding method and apparatus are provided. The decoding method includes extracting an arbitrary down-mix signal and compensation information necessary for compensating for the arbitrary down-mix signal from the input bitstream, compensating for the arbitrary down-mix signal using the compensation information, and generating a three-dimensional (3D) down-mix signal by performing a 3D rendering operation on the compensated arbitrary down-mix signal. Accordingly, it is possible to efficiently encode multi-channel signals with 3D effects and to adaptively restore and reproduce audio signals with optimum sound quality according to the characteristics of an audio reproduction environment.
