如何以某种格式将文件名传递给python中的列表？

  • 772

我正在关注本教程： http: //nbviewer.jupyter.org/github/amsehili/audio-segmentation-by-classification-tutorial/blob/master/multiclass_audio_segmentation.ipynb
在教程的 [8] 块中有：

train_data = {}
train_data["silence"] = ["silence_1.wav", "silence_2.wav",   "silence_3.wav"]  
train_data["speech"]  = ["speech_1.wav", "speech_2.wav", "speech_3.wav", "speech_4.wav", "speech_5.wav"]

即我们正在传递包含在一个文件夹中的 .wav 文件的名称；

我想训练/传递我自己的音乐片段，而不是沉默/演讲。所以，我使用以下方法将一首音乐切成更小的片段：

ffmpeg -i hm1.mp3 -c copy -map 0 -segment_time 1 -f segment hm1_%03d.mp3

这生成了 1201 second long mp3 chunks个原始文件。我使用保存了这些 1 秒块的文件名 

ls >filenames.txt

无法键入 120 "abc.wav" ,what is the best way to pass the all 120+ file names of the generated music bits in the format 如上所示。

ubuntu python
