推荐答案

使用本机Flash声音类，可以读取声音对象的ID3元数据属性，但是这取决于软件的EN codeD的MP3将在元数据中的编码信息。没有什么固有的MP3本身报告给声音类和元数据通常丢失或不可靠的。

Using the native flash sound class, you can read the id3 metadata property of the sound object, however this depends on the software that encoded the mp3 putting the encoding information in the metadata. there's nothing inherent to the mp3 itself that reports this to the sound class, and the metadata is often missing or unreliable.

另外还有用于读取实际MP3头信息，这是更为精确的这个第三方工具。

alternatively there's this 3rd party utility for reading actual mp3 header information, which is much more accurate.
