I need to read metadata (song name, artist, etc.) from various audio files with ruby, mainly MP3 and Apple's AAC. I've googled and found no library that supported both formats.
我需要用ruby从各种音频文件中读取元数据(歌曲名、歌手等)，主要是MP3和苹果的AAC。我搜索了一下，发现没有支持两种格式的库。
How do you guys read audio metadata with ruby? I would prefer a solution with minimal dependencies possible.
你们怎么用ruby读音频元数据?我更喜欢一种可能具有最小依赖性的解决方案。
Thanks.

AAC files are standard QuickTime files with everything stored as Atoms which can be parsed if you can read the raw byte stream.
AAC文件是标准的QuickTime文件，所有文件都存储为原子，如果可以读取原始字节流，就可以解析这些原子。

There is id3lib-ruby gem, but I had some issue with this and some specific MP3s, some worked, some crashed the app entirely. But if you can get it to work, it's nice.
有id3lib-ruby gem，但是我有一些问题，一些特定的mp3，一些有用，一些完全崩溃了应用程序。但如果你能让它工作，那就太好了。
