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

【解决方案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，然后确保下载的 ffmpeg 应用程序的 bin 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。
