Windows記得要先下載ffmpeg，不然會發生錯誤
代碼如下：

import os
import json
from pydub import AudioSegment

# 指定MP3文件所在的文件夹路徑
folder_path = r'path'

mp3_lengths = []

# 取得長度
for i in range(53):
    mp3_path = os.path.join(folder_path, "{}.mp3".format(i))
    audio = AudioSegment.from_file(mp3_path)
    length_in_seconds = len(audio) / 1000
    mp3_lengths.append(length_in_seconds)

# 将字典保存为JSON文件
output_json_path = r'save path'
with open(output_json_path, 'w') as json_file:
    json.dump(mp3_lengths, json_file, indent=4)

print(f'MP3長度已保存到 {output_json_path}')
