第一次碰到Ogg文件是在安卓系统的/system/media/audio/目录下的一些文件夹(alarms/notifications/ringtones/ui等文件夹)里，尽管后缀名非常奇怪，但这种格式的文件已经被广泛传播和使用了。使用十六进制文件查看器任意打开一个OGG文件，可以看到它的文件头的Magic Number为：0x4F676753，转换为文本就是OggS，即这种文件的后缀名的全称：OggSquish [1]。
这种文件格式的优势在于开源，支持多种编码类型，且压缩率高。
我们可以使用Python的一个库 mutagen，简单修改包括Ogg这种文件格式在内的音频文件的元数据（如，标题、作者等……）。
安装mutagen：
python -m pip install mutagen
安装mutagen之后，即可借助这个库简单查看OGG文件的一些基础数据：
import mutagen audio = mutagen.File('ping.ogg') print(audio.pprint()) """输出： Ogg Vorbis, 0.27 seconds, 120000 bps (audio/vorbis) ANDROID_LOOP=false TITLE=android.resource://com.google.android.soundpicker/string/ping """
以及，修改文件的数据：
import mutagen audio = mutagen.File('ping.ogg') print(audio.pprint()) audio['TITLE'] = "Ping" # 修改标题 audio['ARTIST'] = "Google Pixel" # 修改作者 audio.save() # 保存修改 print() print("""--- AFTER MODIFIED ---""") print() modified = mutagen.File('ping.ogg') print(modified.pprint()) """输出： Ogg Vorbis, 0.27 seconds, 120000 bps (audio/vorbis) ANDROID_LOOP=false TITLE=android.resource://com.google.android.soundpicker/string/ping --- AFTER MODIFIED --- Ogg Vorbis, 0.27 seconds, 120000 bps (audio/vorbis) ANDROID_LOOP=false TITLE=Ping ARTIST=Google Pixel """
假设目录都是后缀为ogg的文件，文件命名格式都是xxx_yyy.ogg之类，目标是修改其元数据信息的标题TITLE为Xxx Yyy，可以写出一个批量修改OGG文件标题和作者等元数据的脚本：
import os import re import sys import time import mutagen try: _path = input('Please input ogg files folder path: ') _path = _path.strip('\' ') except KeyboardInterrupt as e: print() print('Good bye.') sys.exit(0) if len(_path) <= 0: print('Param error.') sys.exit(1) print('Ogg files folder path is: [%s]' % (_path, )) print() print('---') print() t0 = time.time() def format_name_str(s: str): parts = s.split('_') capitalized_parts = [part.capitalize() for part in parts] return ' '.join(capitalized_parts) tasks = [] successed_tasks = [] def modify_metadata(file_path: str, title: str, artist: str): try: audio = mutagen.File(file_path) audio['TITLE'] = title audio['ARTIST'] = artist audio.save() print(f'Metadata updated for {file_path}') successed_tasks.append(file_path) except Exception as e: print(f'Error processing {file_path}: {e}') for root, _, files in os.walk(_path): for file in files: if file.lower().endswith('.ogg'): file_path = os.path.join(root, file) tasks.append(file_path) modify_metadata(file_path, format_name_str(re.sub(r'\.ogg$', '', file)), 'Google Pixel') print() print('---') print() print('Processed %d /%d file(s).' % (len(successed_tasks), len(tasks))) print('Cost: %.4f s.' % (time.time()-t0, ))
脚本将会递归遍历指定文件夹下的所有OGG文件，并根据文件名称相应修改文件元数据的标题、修改作者为Google Pixel。
运行结果如下：
