Abstract

The present disclosure relates to a loudness adjustment method, device, electronic equipment, and storage medium, and mainly relates to the field of multimedia technology. The method includes: converting a sound signal of a multimedia resource into a first frequency domain signal; based on the first frequency domain signal and Based on the frequency response information of the current electronic device, the second frequency domain signal is obtained, and the second frequency domain signal is used to reflect the loudness of the first frequency domain signal when played on the current electronic device; based on the second frequency domain signal and the target loudness, the sound is The loudness of the signal is adjusted to obtain the target sound signal of the multimedia resource. This disclosure takes into account the frequency response information of the current electronic device, and converts the original signal into a frequency domain signal that can reflect the loudness of the signal when it is played on the current electronic device, so that the adjusted sound signal is played on the current electronic device. The loudness is close to the target loudness, instead of just adjusting the loudness of the sound signal itself, it matches the user's hearing characteristics, and the effect of loudness adjustment is good.

Description

technical field [0001] The present disclosure relates to the field of multimedia technology, and in particular to a loudness adjustment method, device, electronic equipment and storage medium. Background technique [0002] With the development of multimedia technology, people usually watch or listen to various multimedia resources through multimedia applications, wherein a short video application is a multimedia application. In this kind of multimedia application, most of the multimedia resources are user generated content (User Generated Content, UGC), and the internal sound loudness of a multimedia resource may be different, resulting in the loudness of the sound heard by the user. The loudness of the sound may also be different. During the switching process of the multimedia resource, the user may hear the loudness of the sound fluctuating. Therefore, the loudness of the multimedia resource is usually adjusted. [0003] In the related art, the first loudness adjustment m...
