如何在librosa中找到自定义帧列表的能量？

Question

我试图找到帧列表的能量。我想把它们分为四个标准。例如“弱、正常、强、太强”和使混合数组像

normal_frames_array = [
   6, 34, 52, 71, 88, 107, 125, 143, 161, 198, 216, 234, 271, 289,
   352, 397, 416, 434, 461, 479, 498, 516, 552, 571, 589, 644, 662, 716,
   .
   .
   .
   8204, 8222, 8241, 8259, 8277, 8295, 8313, 8332, 8350, 8368, 8386, 8404, 8423, 8441
]

classified_array = [
   [6, "weak"],
   [34, "normal"],
   [52, "strong"],
   [71, "very strong"],
   .
   .
   .
   [8167, "weak"]
]

我怎样才能在librosa做到这一点
