python aac

要在Python中将音频文件保存为AAC格式，可以使用MoviePy库或pydub库。下面是两种方法的示例代码：

使用MoviePy库：
1. 安装MoviePy库：pip install moviepy
2. 导入MoviePy库：import moviepy.editor as mp
3. 定义音频剪辑：my_clip = mp.AudioFileClip("input_path.opus")
4. 将音频剪辑保存为AAC文件：my_clip.write_audiofile("output_path.aac")

使用pydub库：
1. 安装pydub库：pip install pydub
2. 导入pydub库：from pydub import AudioSegment
3. 读取MP3文件：sound = AudioSegment.from_mp3("input_path.mp3")
4. 设置开始时间和结束时间：start_time = "0:00"，stop_time = "0:42"
5. 将时间转换为毫秒：start_ms = (int(start_time.split(':'))*60 + int(start_time.split(':')))*1000，stop_ms = (int(stop_time.split(':'))*60 + int(stop_time.split(':')))*1000
6. 提取指定时间段的音频：word = sound[start_ms:stop_ms]
7. 保存音频为AAC文件：word.export("output_path.aac", format="aac", tags={'artist': 'AppLeU0', 'album': 'output_file'})

请注意，这些代码仅提供了保存音频为AAC格式的基本操作，您需要将"input_path.opus"和"input_path.mp3"替换为您实际的音频文件路径，并将"output_path.aac"替换为您想要保存的AAC文件路径。<span class="em">1</span><span class="em">2</span>
