To provide an audio information converting method, a video/audio format, an encoder, an audio information converting program, and an audio information converting device such that a listening point can freely be changed and Doppler effect generated by the movement of an object can be adjusted according to the change of the listening point only with one audio stream.
In the audio information converting method, a virtual listening point 101 is determined at a position different from basic positions where sounds of objects 1, 2, and 3 can be listened to, the speed of the object 1 viewed at the virtual listening point 101 is found with position information on the virtual listening point 101 and position information on the object 1, and the audio frequency of a sound listened to at the virtual listening point 101 is varied according to the found speed. For example, when the object 1 approaches the virtual listening point 101, the audio frequency of the sound is increased and when the object 1 moves away from the virtual listening point 101, the audio frequency of the sound is lowered.
