Sound field reconstruction method and device, electronic equipment and storage medium

Abstract

The invention provides a sound field reconstruction method and apparatus, an electronic device and a storage medium. The method comprises the steps: determining an original sound source signal; performing frequency domain filtering on the original sound source signal based on a crosstalk filter to obtain a loudspeaker playing signal in each reconstruction area, wherein the loudspeaker playing signal in each reconstruction area is used for sound field reconstruction of the corresponding reconstruction area, and the crosstalk filter is used for filtering sound source signals except the sound source signal corresponding to any reconstruction area in the original sound source signals to obtain a loudspeaker playing signal in any reconstruction area. According to the sound field reconstructionmethod and device, the electronic equipment and the storage medium provided by the invention, the original sound source signal is subjected to frequency domain filtering by using the crosstalk filter,and the sound source signal except the sound source signal corresponding to any reconstruction area in the original sound source signal is filtered to obtain the loudspeaker playing signal in any reconstruction area; and the sound field reconstruction accuracy is improved.

Description

technical field [0001] The present invention relates to the technical field of audio signal processing, in particular to a sound field reconstruction method, device, electronic equipment and storage medium. Background technique [0002] With the rapid development of 3D movies, virtual reality and other technologies, 3D audio technology has become one of the key technologies to provide users with high-fidelity immersive experience, and has gained more and more attention. As the core of 3D audio technology, sound field reconstruction technology is also playing an increasingly important role. [0003] However, the existing sound field reconstruction methods usually need to decompose the sound field into the spherical harmonic domain, and there are truncation errors, resulting in poor accuracy of the reconstructed sound field. Contents of the invention [0004] The invention provides a sound field reconstruction method, device, electronic equipment and storage medium to solve...
