1-16. (canceled)
An audio processing method comprising:
- providing a first audio signal;
- setting a range according to a size of a virtual sound source, from among a plurality of points each in a different position relative to a listening point;
- generating a second audio signal by imparting, to the first audio signal, a plurality of head-related transfer characteristics corresponding to multiple points within the set range for:
- a right channel by imparting to the first audio signal a plurality of right head-related transfer characteristics for a right ear corresponding to respective points within the set range;
- and
- a left channel by imparting to the first audio signal a plurality of left head-related transfer characteristics for a left ear corresponding to respective points within the set range.
