Title:
SOUND SIGNAL PROCESSING METHOD AND APPARATUS
Document Type and Number:
Japanese Patent JP2016052117
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a sound signal processing method and apparatus.SOLUTION: Embodiments of the present invention disclose a sound signal processing method and apparatus, relate to an audio signal processing field and can collect and process signals in a three-dimensional sound field surrounding a terminal. The method in the present invention includes: acquiring, by a mobile terminal, signals from a three-dimensional sound field, where at least three microphones are disposed on the mobile terminal and one microphone is configured to receive a sound signal in at least one direction; acquiring, according to the acquired sound signals, a direction of a sound source relative to the mobile terminal; and obtaining spatial audio signals according to the direction of the sound source relative to the mobile terminal and the acquired sound signals where the spatial audio signals are used for simulating the three-dimensional sound field. The present invention is applicable to a process of collecting and processing signals in a three-dimensional sound field surrounding a terminal.SELECTED DRAWING: Figure 1
