尝试将 AudioSegment 用于 .wav 文件时出错

Question

我正在尝试遍历文件夹“audios”中的所有 .wav 文件，但收到以下错误。我发现安装 ffmpeg 解决了类似的问题，但没有帮助。

    FileNotFoundError                         Traceback (most recent call last)

          4 
          5     # pass audio file, start time, end time & chunk path to create chunk

FileNotFoundError: [Errno 2] No such file or directory: 'name_of_file.wav'

Answer 1

os.listdir 不会 return 您提供的目录中文件的完整路径，只是它们在该目录中的名称。您需要将此目录名称添加到您传递给 AudioSegment.from_wav.

的文件名之前

尝试替换行

     audio = AudioSegment.from_wav(audio_file)

与

     audio = AudioSegment.from_wav(os.path.join(base_path+"audios", audio_file))

尝试将 AudioSegment 用于 .wav 文件时出错
