先简单说一下MP3的ID3 标记,因为主要是操作这个玩意
MP3最开始的时候没有我们今天看到的那样,有歌手、年代,专集等等信息
只有一些简单的参数如yes/no来表示是不是privated或者copyrighted等信息,这样对MP3的相关工作带来了很多不便,1996年的时候有个老外提出来在每个MP3后面追加一段数据,用以存放上述的那些信息,后来就发展成为id3 v1 据我所知的现在已经到1.1了,具体的还是自己去查一下吧
还是老习惯,用metadata来引入DLL,我以前有文章贴过的,不知道的请自己去查
看代码

for i = 1 to LenB(Binary)
strChar = chr(AscB(MidB(Binary,i,1)))
ConvertBin = ConvertBin & strChar
Next
End Function

if ucase(strTag) = “TAG” then
strSongName = ConvertBin(objStream.Read(30))
strArtist = ConvertBin(objStream.Read(30))
strAlbum = ConvertBin(objStream.Read(30))
strYear = ConvertBin(objStream.Read(4))
strComment = ConvertBin(objStream.Read(30))
end if
‘Display the results

自己试试吧
