Acoustic processing device, acoustic processing method, acoustic processing program, and acoustic processing system

An acoustic processing method, comprising:

• by a computer,
• acquiring a recommended environment defined for each content, the recommended environment including an ideal arrangement of speakers in a space in which the content is reproduced;
• measuring a position of a listener located in the space, a number and arrangement of the speakers, and a space shape;
• and
• correcting audio that is observed at the position of the listener, the audio included in the content emitted from a speaker located in the space, to audio to be emitted from a virtual speaker ideally disposed in the recommended environment on a basis of information that has been measured.

A computer implemented method for acoustic processing, comprising:

• providing a program for causing a computer to function as:
• an acquisition unit that acquires a recommended environment defined for each content, the recommended environment including an ideal arrangement of speakers in a space in which the content is reproduced, wherein the acquisition unit includes an acquisition unit software module;
• a measurement unit that measures a position of a listener located in the space, a number and arrangement of the speakers, and a space shape, wherein the measurement unit includes a measurement unit software module;
• and
• a correction unit that corrects audio that is observed at the position of the listener, the audio included in the content emitted from a speaker located in the space, to audio to be emitted from a virtual speaker ideally disposed in the recommended environment on a basis of information measured by the measurement unit, wherein the correction unit includes a correction unit software module.

An acoustic processing system comprising an acoustic processing device and a speaker,

• wherein the acoustic processing device comprises:
• an acquisition unit that acquires a recommended environment defined for each content, the recommended environment including an ideal arrangement of speakers in a space in which the content is reproduced, wherein the acquisition unit includes an input;
• a measurement unit that measures a position of a listener located in the space, a number and arrangement of the speakers, and a space shape, wherein the measurement unit includes a sensor;
• and
• a correction unit that corrects audio that is observed at the position of the listener, the audio included in the content emitted from a speaker located in the space, to audio to be emitted from a virtual speaker ideally disposed in the recommended environment on a basis of information measured by the measurement unit, wherein the correction unit includes a correction unit software module,
• the speaker comprises:
• an audio emission unit that emits an audio signal toward a predetermined portion of the space;
• and
• an observation unit that observes reflected sound of the audio signal emitted by the audio emission unit, and
• the measurement unit measures the space shape on a basis of a time having elapsed from emission of the audio signal by the audio emission unit to observation of the reflected sound by the observation unit.
