| 摘要 | Surround audio decoding for selectively generating an audio signal from a multi-channel signal. In the surround audio decoding, a down-mixed signal, e.g., as down-mixed by an encoding terminal, is selectively up-mixed to a stereo signal or a multi-channel signal, by generating spatial information for generating the stereo signal, using spatial information for up-mixing the down-mixed signal to the multi-channel signal. | ||

| 主权项 | 1. A method for generating a stereo signal, comprising: calculating, using at least one processor, first spatial information for up-mixing a down-mixed mono signal to the stereo signal, using second spatial information for up-mixing the down-mixed mono signal to a multi-channel signal other than the stereo signal; and up-mixing the down-mixed mono signal to the stereo signal using the calculated first spatial information for up-mixing the down-mixed mono signal to the stereo signal, wherein the second spatial information for up-mixing the down-mixed mono signal to the multi-channel signal other than the stereo signal pre-exists as being generated by an encoder that generates the down-mixed mono signal. | ||
