我使用Librosa函数librosa.output.write_wav输出时间序列作为.wav文件，然后尝试在pydub中打开它，但是pydub正在抛出FileNotFoundError消息（见下文） ）。 * .wav文件肯定与我的Jupyter笔记本（convert_spect_to_wav.ipynb）位于同一目录中。奇怪的是，如果我输入由Librosa生成的不的* .wav文件，我的代码就可以正常工作。我能够收听Librosa * .wav文件，所以我不知道Librosa正在做什么奇怪的事情让pydub找不到Librosa * .wav文件。

我不知道为什么pydub找不到Librosa输出的* .wav文件。使用Librosa * .wav文件的问题是 ，因为其他* .wav文件可以正常工作。有没有其他人遇到过这个？
这里有一些相关代码：write_time_series_to_wav创建Librosa * .wav文件，stitch_wavs_together是我尝试使用pydub和{{1}读取Librosa * .wav文件的地方调用这两个函数。
convert_spect_to_wav感谢任何帮助或意见!!
