一种虚拟低音增强方法、装置、智能设备

By generating high-frequency and low-frequency signals separately in a small speaker and dynamically adjusting them using a harmonic generation algorithm, the problem of not being able to simultaneously enhance the listening experience of vocals and drum sounds in existing technologies has been solved, achieving a better listening experience for both vocals and drum sounds in a small speaker.

Abstract

本申请提供了一种虚拟低音增强方法、装置、智能设备，该方法首先分别确定出主链路生成的高音频带信号及辅链路生成的低音频带信号；然后将高音频带信号和低音频带信号进行整合，得到输出信号；其中，低音频带信号是对输入信号中各类音乐成分，分别利用相应谐波生成方式生成的；高音频带信号是依据输入信号中的预设高频信号生成的；也即本申请中的低音频带信号是通过辅链路对输入信号中各类音乐成分，分别利用相应谐波生成算法得到的，能够动态获得输入信号在不同音乐中的虚拟成分，使得输入信号的人声和鼓声都具有较好的听感，解决了现有相关方案直接利用原曲的低频成分去生成谐波成分，无法同时保证人声和鼓声的听感都有效提高的问题。
