python - 有没有以下问题的解决方案

Question

这是代码，我得到以下问题文件名是“ply_audio.py”

    from pydub import AudioSegment
    ># read/write data
    > data = AudioSegment.from_file(file="one.wav",format="wav")
    >data.export("new_test.wav")
 > python ply_audio.py

Answer 1

您使用的库需要 ffmpeg(或 avconv)。我建议使用 ffmepg (但如果需要，您应该检查项目的许可证限制)。
您可以从 official 下载它然后确保 bin下载的 ffmpeg 应用程序的文件夹在您的路径中(例如，参见 https://www.wikihow.com/Install-FFmpeg-on-Windows)
然后您上面的代码将同时看到 ffmpeg 和 ffprobe 二进制文件。
