SoXI失败，退出代码为1

Question

我想将mp3文件转换为wav 16khz（这些是来自Mozilla Common Voice的文件）

我的职能

def one_sample(mp3_filename):
    """ Take an audio file, and optionally convert it to 16kHz WAV """
    if not os.path.splitext(mp3_filename.lower())[1] == ".mp3":
        mp3_filename += ".mp3"
    # Storing wav files next to the mp3 ones - just with a different suffix
    wav_filename = os.path.splitext(mp3_filename)[0] + ".wav"
    if not os.path.exists(wav_filename):
        transformer = sox.Transformer()
        transformer.convert(samplerate=SAMPLE_RATE, n_channels=CHANNELS)
        try:
            transformer.build(mp3_filename, wav_filename)
        except sox.core.SoxError:
            pass

我收到所有文件的错误信息：
