Abstract
An apparatus and method for generating a panoramic sound are provided. The panoramic sound generation apparatus may include a panning coefficient calculation unit to calculate a panning coefficient that represents directivity of a sound source using an input signal, a masker determination unit to determine a direction masker that extracts a sound source of a desired direction based on the panning coefficient, and a channel separation unit to separate to be used as an output signal, output to a sound output device, using the direction masker.
Claims22
A panoramic sound generation apparatus comprising:
- a panning coefficient calculation unit, using at least one processor, to calculate a panning coefficient that represents directivity of a sound source using an input signal;
- a masker determination unit to determine a direction masker that extracts a sound source of a desired direction based on the panning coefficient;
- and
- a channel separation unit to separate the input signal to be used as an output signal, and to output the output signal to a sound output device, using the direction masker.
A panoramic sound generation method comprising:
- calculating, using at least one processor, a panning coefficient that represents directivity of a sound source using an input signal;
- determining a direction masker that extracts a sound source of a desired direction based on the panning coefficient;
- and
- separating the input signal to be used as an output signal, and outputting the output signal to a sound output device, using the direction masker.
