将音频拆分为更小的 5 秒块，但元组索引错误超出范围

Question

我想将音频拆分成更小的 5 秒块

import librosa
import librosa.display
from pydub import AudioSegment
import IPython.display as ipd
import soundfile as sf
from pydub.silence import split_on_silence

filename= "/content/drive/MyDrive/Colab Notebooks/22__19_07_13_adventure_maniobra.wav"
y,sr = librosa.load(filename, sr=None)
for i in range(0, len(filename), 5 * sr):
  u = filename[5 * sr * i: 5 * sr *(i+1)]
  sf.write("dest_audio"+str(i)+".wav", u, sr) 

我遵循的代码 https://groups.google.com/g/librosa/c/6UE47GMz0aM 但在

sf.write

函数中出现错误：
