Audio information transforming method, audio information transforming program, and audio information transforming device

摘要

The present invention provides an audio information transforming device, an audio information transforming method, and an audio information transforming program, which are capable changing a listening point freely only by one audio stream and also achieving multiple channels only by the 1-channel audio information. In the provided method, a virtual listening point 105 is decided, and then an allocation ratio of the audio to a plurality of loudspeakers is changed based on a ratio of a distance between the virtual listening point 105 and an object 103 and a distance between the object 103 and a basic listening point 102 . Accordingly, a large number of audio environments can be produced by changing information of the virtual listening point 105 based on one audio information.
