Loudness regulation method and device

Abstract

The embodiment of the invention provides a loudness regulation method and device, wherein the method includes the steps of: obtaining the first loudness of the sound signal at the current processing time of the on-line live multimedia file in an electronic device; determining the regulating variable of the first target loudness based on the first loudness and the preset threshold of the first loudness; applying the regulating variable of the first target loudness to the sound signal of the multimedia file sent at the current processing time; compared with the prior art, for an on-line live broadcast process, no matter what the original loudness of the sound signal of the multimedia document is, after the calculation and application of the regulating variable of the first loudness, the actual loudness finally heard by the user is the first loudness threshold. Therefore, the loudness regulation method and device can favorably ensure the loudness consistency during the on-line live broadcast of multimedia files, thereby bringing better experience in hearing to users.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a loudness adjustment method and device. Background technique [0002] In the field of Internet technology, multimedia (audio / video) files have gradually become an important part of online entertainment for users. According to statistics, the flow of multimedia files has accounted for more than 80% of the entire Internet flow. Generally speaking, multimedia files on the Internet mainly include: user-created multimedia files and multimedia files produced by professional production organizations. Generally speaking, if the multimedia file is the content created by the user, the quality of the multimedia file cannot be guaranteed because the original user who produced the multimedia file may not be professional enough; Professional production, so the multimedia file is well-made, and its quality can generally be better guaranteed. [0003] Whether it is an original multimedia...

Problems solved by technology

Specifically, for original multimedia files, since the loudness (i.e. volume) of multimedia files is specified by the original users, and the production levels of original users are uneven, many original users will not consider how to determine the volume of multimedia files. The loudness at each time point can give users a better listening experience, which may cause the loudness of the sound heard by users watching the live broadcast of the multimedia file to fluctuate.

For multimedia files produced by professional organizations, since different multimedia files may originate from different production organizations or be produced by different professionals, the loudness of each multimedia file may also be different. When switching between multimedia files, the loudness of the sound heard by the user is also different, which will also bring a very bad listening experience to the users watching the live broadcast
