Audio signal processing method and device and readable storage medium

Abstract

The embodiment of the invention provides an audio signal processing method and device and a readable storage medium, and the method comprises the steps: obtaining an audio signal, carrying out the spectral analysis of the audio signal, and obtaining a first frequency spectrum corresponding to the audio signal; determining a target frequency component according to the amplitude of each frequency component in the first frequency spectrum and a masking curve of a target object, the target frequency component being a frequency component of which the amplitude is smaller than that of the masking curve in each frequency component; and adjusting the amplitude of the target frequency component according to the masking signal ratio of the target frequency component to obtain a processed audio signal. According to the scheme, by suppressing the amplitude of the frequency component of which the intensity is smaller than that of the masking curve and the masking signal is relatively high, the masking effect of the frequency component which cannot be heard clearly originally on other effective frequency components is reduced, so that the sound clarity is improved, and a user can obtain a betterhearing effect.

Description

technical field [0001] The embodiments of the present application relate to audio processing technologies, and in particular, to an audio signal processing method, device, and readable storage medium. Background technique [0002] At present, there are more and more devices with audio playback functions, such as TV sets, smart phones, earphones, MP3, MP4 and so on. For a device with an audio playback function, it is a crucial task to process the audio signal to obtain a better hearing effect. In order to obtain better auditory effects for different types of objects, people put forward the concept of "exclusive human voice effect". Type object to specify the sound effect. [0003] In the prior art, the hearing threshold of the target object is usually obtained first, and then according to the masking curve between different frequency bands of the audio signal and the hearing threshold of the target object, compensation is made for frequency components whose audio signal int...

[0004] However, using the above method to compensate the frequency component whose audio signal intensity is lower than the hearing threshold of the target object, although the frequency component can be heard clearly, due to the auditory masking effect between the signals of different frequency components, the frequency component after compensation The masking effect on other frequency components may be enhanced, resulting in the signal of other frequency components may not be heard, resulting in poor hearing effect
