Audio processing device and method therefor

An audio processing method, comprising:

• in an audio processing device:
• calculating corrected position information that indicates a first position of a sound source relative to a listening position at which sound from the sound source is heard, wherein
• the corrected position information is calculated based on position information and listening position information,
• the position information indicates a second position of the sound source relative to a standard listening position, and
• the listening position information indicates the listening position;
• performing three-dimensional vector base amplitude panning (VBAP) on a waveform signal of the sound source to generate reproduction signals on M channels, wherein
• the M is three or more, and
• the reproduction signals on the M channels are generated based on the corrected position information;
• and
• converting the reproduction signals on the M channels into reproduction signals on two channels.

A non-transitory computer-readable medium having stored thereon computer-executable instructions that, when executed by a processor, cause the processor to execute operations, the operations comprising:

• calculating corrected position information that indicates a first position of a sound source relative to a listening position at which sound from the sound source is heard, wherein
• the corrected position information is calculated based on position information and listening position information,
• the position information indicates a second position of the sound source relative to a standard listening position, and
• the listening position information indicates the listening position;
• performing three-dimensional vector base amplitude panning (VBAP) on a waveform signal of the sound source to generate reproduction signals on M channels, wherein
• the M is three or more, and
• the reproduction signals on the M channels are generated based on the corrected position information;
• and
• converting the reproduction signals on the M channels into reproduction signals on two channels.
