Question

Python初学者寻求一些帮助。

我正在使用pydub的silence模块来分割和导出音频文件的块。我正在使用对此问题的最高回复中找到的方法：

Using pyDub to chop up a long audio file

chunks = split_on_silence(sound, 
    # length of silence in ms
    min_silence_len=325,

    # consider it silent if quieter than -60 dBFS
    silence_thresh=-60
)

for i, chunk in enumerate(chunks):
    chunk.export(os.path.join(full_path, transcript_filename + "{0}.wav".format("%02d" % i)), format="wav")

现在，沉默不包括在块中。我希望他们留在最后。我假设我要做的修改是pydub.silence函数，但我不知道需要做什么改变。现在是split_on_silence：

def split_on_silence(audio_segment, min_silence_len=1000, silence_thresh=-16, keep_silence=100):

    """
    audio_segment - original pydub.AudioSegment() object
    min_silence_len - (in ms) minimum length of a silence to be used for a split. default: 1000ms
    silence_thresh - (in dBFS) anything quieter than this will be considered silence. default: -16dBFS
    keep_silence - (in ms) amount of silence to leave at the beginning and end of the chunks. Keeps the sound from sounding like it is abruptly cut off. (default: 100ms)
    """

    not_silence_ranges = detect_nonsilent(audio_segment, min_silence_len, silence_thresh)

    chunks = []
    for start_i, end_i in not_silence_ranges:
        start_i = max(0, start_i - keep_silence)
        end_i += keep_silence

        chunks.append(audio_segment[start_i:end_i])

感谢您的帮助。

您可能会发现pydub.silence.detect_silence() function很有用。它返回一个检测到静音的范围列表（它在静音功能的分割中使用）

如果更有帮助，还有pydub.silence.detect_nonsilent（）

如何使用pydub在静音结束时拆分音频文件而不删除静音？
