Question

我无法理解如何正确使用PyDub。我想将较大的mp3剪切为较小的文件，尽管我无法实现使用起点和终点正确剪切每个曲目的方法。

我使用了一种方法，将定义的端点传递到数组中，然后使用该方法来剪切轨道。但是，这就引入了问题，即歌曲每次从0开始播放，即0-2：34、0-5：34、0-9：32等。

我尝试运行时也会遇到内存错误

global tracks

# track list no. array
tracklisting = []
# track list song endpoint array
tracklisting_range = []
# the mp3 file
sound = AudioSegment.from_mp3("somemix.mp3")

def track():
    tracks = int(input("How many tracks?"))
    while True:
        if (tracks > 0):
            return tracks
        else:
            tracks = int(input("Invalid number, please try again:"))


if __name__ == "__main__":
    no_track = track()

    # takes amount of tracks, ask endpoint for each, stores them in a list

    for i in range(no_track):
        temp_val = int(input("Select endpoint for for Track {0} ".format(i)))
        tracklisting.append(temp_val)

    tracklisting_range = pd.Series(tracklisting)
    tracklisting_range = tracklisting_range.astype(int)

    # know we have an array full of end points in milliseconds
    print((tracklisting_range * 100000).to_list())

# pass list so it can cut music
# TODO figure out how to cut song from last endpoint

for i in range(tracklisting_range):
    x = x + 1
    track = sound[i:]
    track.export("Track %x", format="mp3")

我想要的结果是已经能够知道最后一个切割点在哪里，然后从那里开始。但是，浏览文档时，我看不到如何进行设置。从我的角度来看，这首歌是从0开始的，您只能设置要剪切的位置，而不是剪切的位置。
