使用 Pydub 剪切音频文件返回空文件问题排查与解决

from pydub import AudioSegment
import os

path = input("Enter path of mp3 file: ")
song = AudioSegment.from_mp3(path)
start = input("At which second shall the new file begin?: ")
start = int(start) * 1000
end = input("At which second shall the new file end?: ")
end = int(end) * 1000
newmp3 = song[start:end]

# 更健壮的文件名修改方式
file_name, file_ext = os.path.splitext(path)
new_path = file_name + "_new" + file_ext

newmp3.export(new_path, format="mp3")
print("New Audio File is created and saved")

from pydub import AudioSegment

path = input("Enter path of mp3 file: ")
song = AudioSegment.from_mp3(path)
audio_length = len(song) # 获取音频文件的长度（毫秒）

start = int(input("At which second shall the new file begin?: ")) * 1000
end = int(input("At which second shall the new file end?: ")) * 1000

# 检查时间参数的有效性
if start < 0:
    start = 0
if end > audio_length:
    end = audio_length
if start >= end:
    print("Error: Start time must be less than end time.")
else:
    newmp3 = song[start:end]
    newmp3.export("new.mp3", format="mp3")
    print("New Audio File is created and saved")

import os
from pydub import AudioSegment

path = input("Enter path of mp3 file: ")

# 检查文件是否存在
if not os.path.exists(path):
    print(f"Error: File not found at {path}")
else:
    try:
        song = AudioSegment.from_mp3(path)
        # ... 剩余代码
    except Exception as e:
        print(f"Error: Could not load audio file: {e}")
