Abstract
Provided is a method and apparatus for reproducing a three-dimensional (3D) sound field. A method of reproducing a 3D sound field may determine a control region based on a wavelength of an excitation frequency, set, based on a loudspeaker array, at least one candidate control point in the control region, and determine a non-uniform control point corresponding to a non-uniform loudspeaker.
Claims14
A method of reproducing a three-dimensional (3D) sound field, the method comprising:
- determining a control region based on a wavelength of an excitation frequency;
- setting, based on a loudspeaker array, at least one candidate control point in the control region;
- determining, from the at least one candidate control point, a non-uniform control point corresponding to a non-uniform loudspeaker;
- and
- determining whether to add the non-uniform control point to a control point.
An apparatus for reproducing a three-dimensional (3D) sound field, the apparatus comprising:
- a control region determining unit to determine a control region based on a wavelength of an excitation frequency;
- a setting unit to set, based on a loudspeaker array, at least one candidate control point in the control region;
- and
- a control point determining unit to determine, from the at least one candidate control point, a non-uniform control point corresponding to a non-uniform loudspeaker.
