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

我的功能

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：

During handling of the above exception, another exception occurred:

我下载了 sox-14-4-2 并将其添加到 PATH 我使用 PyCharm

【解决方案1】：

First reason

第二个 - 需要文件的完整路径

【讨论】：

好吧，你赢是为了简洁，但这不是解决我遇到同样错误的原因。

【解决方案2】：

尝试从命令行运行 sox。它会给你更多的信息错误。

$ sox --i -c data/stereo-test.mp3

就我而言，它告诉我没有 mp3 文件的库：

$ sox --i -c data/stereo-test.mp3 
sox FAIL formats: no handler for file extension `mp3'

在 Windows 系统上，您必须install the correct DLLs。

在 linux 系统上：

$ sudo apt-get install libsox-fmt-mp3
