Abstract

The invention discloses an angle-based sound field reconstruction method and apparatus, an audio device, and a storage medium. The angle-based sound field reconstruction method disclosed by the invention comprises the following steps: when an object to be measured is identified, extracting a plurality of measurement points from a position area where the object to be measured is located, and determining a center point corresponding to the plurality of measurement points; when a rotation operation is monitored, extracting a target rotation angle from the rotation operation; generating a corresponding target distribution weight in a preset sound field reconstruction model according to the target rotation angle; and adjusting a reconstructed sound signal according to the target distribution weight to complete the reconstruction of a sound field. In the angle-based sound field reconstruction method disclosed by the invention, the possible rotation operation is considered, and the reconstruction of the sound field is completed based on the target rotation angle in the rotation operation, so that the reconstructed sound field has a better hearing effect for the rotated object to be measured, thereby solving the technical problem that the change of a sound listening point is not considered during the sound field reconstruction of the existing three-dimensional audio technology.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional audio, in particular to an angle-based sound field reconstruction method, audio equipment, a storage medium and a device. Background technique [0002] With the continuous development and gradual application of virtual reality (Virtual Reality, VR) technology, 3D audio technology, as a technology that can bring users a better sense of auditory immersion, has gradually become a research hotspot. [0003] The three-dimensional audio technology mainly refers to the technology that restores sound from the three-dimensional level to bring more realistic auditory effects to users. However, the current three-dimensional audio technology still has certain technical defects. [0004] Specifically, in order to restore the sound on the three-dimensional level, the sound field reconstruction of virtual perception is mostly realized based on the physical properties of the sound. However, the ...
