哪位高手知道怎么获得mp3中的id3信息
谁知道如何获得mp3中的id3信息?
最好给个源程序,谢谢
------解决方案--------------------

http://id3lib.sourceforge.net/
这个需要一个id3lib.dll的库
http://www.codeproject.com/audio/cmp3tags.asp
这个不需要库，但是算法比较简单
------解决方案--------------------
下面是ID3V1和V2的定义，很简单的
不过ID3 V2的WXXX tag有点古怪，tag的记录内容大小的长度和内容实际长度不一样，总要多1，2个字节，你自己可以测试一下
-------------------------
ID3v1
ID3V1比较简单，它是存放在MP3文件的末尾，用16进制的编辑器打开一个MP3文件，查看其末尾的128个顺序存放字节，数据结构定义如下：
char Header[3]; /*标签头必须是 "TAG "否则认为没有标签*/
char Title[30]; /*标题*/
char Artist[30]; /*作者*/
char Album[30]; /*专集*/
char Year[4]; /*出品年代*/
char Comment[30]; /*备注*/
char Genre; /*类型*/
ID3V1的各项信息都是顺序存放，没有任何标识将其分开，比如标题信息不足30个字节，则使用 '\0 '补足，否则将造成信息错误。Genre使用原码表示，对照表如下：
/* Standard genres */
0= "Blues ";
1= "ClassicRock ";
