Description

TECHNICAL FIELD

[0002] With the rapid development of digital media technology and the wide popularity of intelligent terminals, users' demand for high-quality audio experience is growing. As an important carrier of information transmission and entertainment enjoyment, the sound quality level of audio playback equipment has become one of the key indicators for measuring user experience. In the processing link of audio signals, volume adjustment and dynamic range control are important links to ensure clear and comfortable listening in different scenarios.

[0003] In the prior art, the volume and dynamic range during the audio playback process are controlled mainly by using an audio equalizer. The equalizer changes the frequency response characteristics of the audio signal by adjusting the gain or attenuation of different frequency bands (such as bass, midrange, and treble). However, it also has corresponding deficiencies, including: (1) non-automation: manual intervention is required to control and adjust the audio with the audio equalizer; (2) non-real-time: when there is no manual intervention, but the audio needs to be controlled and adjusted, a preset fixed audio equalizer parameter is used for non-real-time static control and adjustment of the played audio; (3) unable to automatically control the volume reciprocally: the parameters of the traditional audio equalizer are usually fixed after being set, or change unidirectionally according to a preset rule, and cannot generate a dynamic volume curve with periodicity and reversibility.

[0004] Therefore, how to provide an effective technical solution to solve the problems of non-automation, non-real-time, and inability to automatically control the volume reciprocally in the prior art has become a difficult problem to be solved in the prior art. SUMMARY
