Abstract

Embodiments of the present application provide an audio signal processing method and an electronic device. In this method, for the audio signal to be played, the optimization model generates the filter coefficient corresponding to the audio signal according to the audio content analysis result corresponding to the audio signal, the preference information input by the user and the feedback information of the Smart PA; the filtering optimization model After filtering and optimizing the audio signal to be played according to the filter coefficient, the audio signal is output to the speaker for playback, so as to reduce the power consumption and temperature when the speaker plays audio. In this way, it not only reduces the power consumption and heat generation of electronic devices, but also ensures the user's hearing experience. Since the filter optimization also combines the Smart PA feedback information, there will be no obvious fluctuation in the audio playback performance that the user can perceive.

Description

technical field [0001] The present application relates to the technical field of intelligent terminals, and in particular, to an audio signal processing method and electronic device. Background technique [0002] Although the functions of smart terminals (such as mobile phones, etc.) are increasingly rich, audio services (calls, incoming calls, music, videos, etc.) have always been the basic and important functions of smart terminals. [0003] With the increasing demand for stereo speakers of smart terminals, dual-speaker terminals and even multi-speaker terminals are becoming more and more popular. At this time, the stereo external amplifier greatly consumes the battery power of the terminal, and due to the low electro-acoustic conversion efficiency, the terminal heats up seriously. Therefore, how to reduce the power consumption of the intelligent terminal is an urgent problem to be solved when the intelligent terminal plays audio. SUMMARY OF THE INVENTION [0004] In o...
