Sound mixing method and device and terminal equipment

Abstract

The invention provides a sound mixing method, a sound mixing device and terminal equipment. The method comprises the following steps: acquiring a current system volume parameter of terminal equipment,adjusting a sound mixing parameter of the sound material according to the system volume parameter and the frequency range of the sound material, performing sound mixing processing on the sound materials according to the sound mixing parameters, and playing the sound material after sound mixing processing. According to the invention, the sound mixing parameter of the sound material can be adjustedaccording to the acquired current system volume parameter of the terminal device and the frequency of the sound material, different sound mixing parameters can be adopted for the sound material underdifferent system volume parameters, and the sound material is played according to the sound mixing parameters. According to the method, the hearing difference of the sound in each frequency range under different volumes can be reduced, a user can obtain comfortable hearing under various volumes, and the hearing experience of the user is improved.

Description

technical field [0001] The present invention relates to the technical field of audio processing, in particular to a sound mixing method, device and terminal equipment. Background technique [0002] In related technologies, when engineers mix multiple sound materials, they mostly adjust a set of fixed sound mixing schemes based on the human ear's sense of hearing when the device plays sound; The volume of sound playback in each frequency band usually changes linearly with the volume of the system. However, the human ear has different sensitivity to sounds in different frequency bands. For the same hearing effect, the volume of high-frequency sounds is lower than that of low-frequency sounds; at the same time, the sensitivity is also affected by the system volume and playback hardware. The hearing effect of the sound in each frequency band reaching the human ear will not change linearly with the change of the system volume, and the inherent disadvantages of the hardware will ...

However, the human ear has different sensitivity to sounds in different frequency bands. For the same hearing effect, the volume of high-frequency sounds is lower than that of low-frequency sounds; at the same time, the sensitivity is also affected by the system volume and playback hardware. The hearing effect of the sound in each frequency band reaching the human ear will not change linearly with the change of the system volume, and the inherent disadvantages of the hardware will exacerbate this difference

For example, at the same playback volume, the loudness of the high frequency band of the sound material played by the external speaker of the mobile phone reaches the human ear is higher than that of the low frequency band; when the user adjusts the system volume, the change trend of the loudness of the sound of each frequency band reaches the human ear different, resulting in differences in the sense of hearing of the sound of each frequency band at different volumes, thus affecting the user's hearing experience
