Embodiment Construction

[0049] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0050] The inventor found through research that in order to improve the three-dimensional sound effect of the sound field, a two-channel or multi-channel system is usually used to enhance the three-dimensional sound effect of the sound field. The phenomenon of strong sound influence makes the human ear only hear strong sound but not weak sound, t...

Abstract

The present application relates to a sound field expansion method, computer equipment, and a computer-readable storage medium. The method includes the following steps: acquiring at least two channel signals, wherein the at least two channel signals include a first channel signal and a first channel signal. second channel signal; acquiring a first gain signal and a third gain signal corresponding to the first channel signal, and a second gain signal corresponding to the second channel signal; according to the first gain signal and the obtained obtaining a first loudness compensation signal through the second gain signal; obtaining an output signal of the first channel signal according to the third gain signal and the first loudness compensation signal. Loudness compensation is used to remove strong sounds, and to amplify and enhance weaker sounds that cannot be detected by the human ear due to the masking effect, so that they can be perceived by the human ear, improving the three-dimensional sound effect and restoring the real sound field.

Description

technical field [0001] The present application relates to the technical field of sound processing, in particular to a method for expanding a sound field, computer equipment, and a computer-readable storage medium. Background technique [0002] Televisions and cinemas are audio-visual products, and the picture quality and sound quality have always been the content that consumers pay attention to. In terms of sound, in addition to the quality of the output sound, the sense of presence is also an aspect that users are paying more and more attention to. The sound system of a TV is generally two-channel, which can only reproduce part of the spatial information of the sound. The sound heard by the user feels that it is transmitted from the TV, and cannot reproduce the three-dimensional spatial effect. Usually, a multi-channel playback system is used to enhance the three-dimensional spatial effect, but special program sources and multi-speaker playback conditions are required, whi...
