Problems solved by technology

[0003] However, the smaller the size of smart audio products, the lower the bass resonant frequency will not be low enough to achieve better low-frequency sound effects
In related technologies, an equalizer is usually used to boost the output power of low-frequency signals. However, the low-frequency boost in this way is limited, and there is a problem of serious distortion of the audio signal, which cannot achieve a better low-frequency sound effect.
In addition, this method will also cause damage to the speaker

Abstract

The embodiment of the invention disclose an audio signal processing method and device, and an electronic equipment. The audio signal processing method comprises the steps of obtaining a to-be-processed audio signal; dividing the to-be-processed audio signal into two paths to obtain a first path of audio signal and a second path of audio signal; obtaining a low-frequency processing mode which comprises a target low-frequency type and a target processing mode; determining whether the second path of audio signal contains an audio signal corresponding to the target low-frequency type, and if so, processing the second path of audio signal according to the target processing mode to obtain a processed second path of audio signal; and carrying out superposition processing on the first path of audio signal and the processed second path of audio signal to obtain a target audio signal.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of signal processing, and more specifically, embodiments of the present disclosure relate to an audio signal processing method, device, and electronic equipment. Background technique [0002] At present, people have higher and higher requirements for the performance of smart audio products. On the one hand, smart audio products are required to be compact and portable, and on the other hand, smart audio products are required to have better sound quality. [0003] However, the smaller the size of smart audio products, the lower the bass resonance frequency will not be low enough to achieve better low-frequency sound effects. In the related art, an equalizer is usually used to boost the output power of the low-frequency signal. However, the low-frequency boost in this way is limited, and there is a problem of serious distortion of the audio signal, which cannot achieve a better low-freque...
