Abstract

The invention relates to an audio loudness balancing method and device. The method comprises the following steps: acquiring a to-be-balanced audio; framing the audio to be balanced, and determining the loudness of each frame of audio according to a preset loudness calculation mode; determining the global average loudness, the global maximum loudness and the global minimum loudness of the to-be-balanced audio according to the loudness of each frame of audio; determining a level fluctuation zoom ratio of each frame of audio according to the global average loudness, the global maximum loudness, the global minimum loudness and preset loudness fluctuation; determining a global level scaling ratio of the audio to be balanced according to the global average loudness and a preset average loudness; and according to the level fluctuation scaling ratio and the global level scaling ratio, carrying out loudness equalization on the audio to be equalized. According to the scheme disclosed by the invention, the audio loudness can be balanced through combination of mean migration and fluctuation range scaling according to the loudness fluctuation and the average loudness expected by the user, so that the stimulation of accent to human ears is reduced while the improvement of the gentle sound hearing feeling is ensured, and the hearing experience is improved.

Description

technical field [0001] The present disclosure generally relates to the technical field of audio signal processing. More specifically, the present disclosure relates to audio loudness equalization methods and devices. Background technique [0002] At present, with the development of audio processing technology, the audio after audio processing brings better and better auditory experience to people. However, in the same audio or video file, there are often large-scale loudness fluctuations, making soft sounds difficult to be felt by human ears or heavy sounds that are irritating to human ears. Therefore, it is necessary to perform loudness equalization on audio files or audio in video files. However, the existing loudness equalization technology is still unsatisfactory. [0003] Therefore, how to obtain a better audio loudness equalization method is a problem to be solved in the prior art. Contents of the invention [0004] In order to at least partly solve the technical...
