Title:
LOUDNESS ADJUSTMENT METHOD AND APPARATUS, AND ELECTRONIC DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/103527
Kind Code:
A1
Abstract:
The present application relates to a loudness adjustment method and apparatus, and an electronic device and a storage medium, mainly relating to the technical field of multimedia. The method comprises: converting a sound signal of a multimedia resource into a first frequency domain signal; acquiring a second frequency domain signal based on the first frequency domain signal and frequency response information of a current electronic device, wherein the second frequency domain signal is used for reflecting the loudness of the first frequency domain signal when same is played on the current electronic device; and adjusting the loudness of the sound signal based on the second frequency domain signal and a target loudness, so as to obtain a target sound signal of the multimedia resource. In the present application, frequency response information of a current electronic device is taken into consideration, and an original signal is converted into a frequency domain signal capable of reflecting the loudness of the signal when same is played on the current electronic device, so that the loudness of an adjusted sound signal when same is played on the current electronic device is approximate to a target loudness, without only adjusting the loudness of the sound signal itself, and the loudness matches a hearing characteristic of a user, and there is a good loudness adjustment effect.
