music_point's Introduction

音乐卡点

由于对数字信号处理方面了解较少，主要使用librosa处理音频

  1. 分析整个音频，找到节奏区域（能量强度变化最大的区域）（暂未找到适合方法确定节奏区间）
  2. 在节奏内跟踪节拍，确定卡点时间
    • 程序判断beat与演奏者不一定合拍，需对节拍做误差分析
    • 节拍的1/4、2/4、3/4、4/4均可能为卡点，将其与信号峰值做交集，为卡点

遗留问题：

  1. 不能判断出哪段音乐更适合卡点
  2. 准确率不高，容易受杂音干扰，人声影响特别大（尤其是连续的节奏较快的高音）

基于上述问题，深耕《数字信号处理》寻找解决办法
