Embodiment Construction

[0020] In order to make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions of the present application will be described clearly and completely in conjunction with specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of this application.

[0021] In the prior art, physical structures such as foam pads are usually used to reduce the abnormal sound of audio playback products through buffering methods. However, the production process of this method is complicated and the production cost is relatively high. In some embodiments of the present application: before the audio signal is broadcast, accordin...

Abstract

An embodiment of the invention provides an audio signal processing method and equipment and a storage medium. The method includes: acquiring a frequency distribution range of an audio signal to be played by audio playing equipment; if target frequency matched with resonant frequency of the audio playing equipment exists in the frequency distribution range, determining amplitude reduction amount corresponding to the target frequency according to a corresponding relationship between the resonant frequency and the amplitude reduction amount; adjusting an amplitude value of the audio signal at thetarget frequency according to the amplitude reduction amount corresponding to the target frequency; outputting an audio signal after the amplitude value is adjusted through the audio playing equipment. Abnormal sound generated by the audio playing equipment due to resonance when the audio signal is broadcasted can be reduced by lowering the amplitude value at the target frequency causing resonance in the audio signal and broadcasting the audio signal after amplitude adjusting.

Description

Technical field [0001] This application relates to the field of sound processing technology, and in particular to an audio signal processing method, device and storage medium. Background technique [0002] At present, when the audio playback products on the market play audio, when the frequency of the audio is within the resonance frequency range of the audio playback products, it will cause the audio playback products to produce abnormal sounds such as tremolo, which will affect the user experience. For example, resonance can cause a lot of abnormal sounds from the speakers. [0003] In the prior art, physical structures such as foam pads are usually used to reduce the abnormal sound of audio playback products through buffering methods. However, the production process of this method is complicated and the production cost is relatively high. Summary of the invention [0004] Various aspects of the present application provide an audio signal processing method, device, and storage m...
