用ASP实现对MP3曲目信息的操作
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
<%
Function ConvertBin(Binary)
'This function converts a binary byte into an ASCII byte.
for i = 1 to LenB(Binary)
strChar = chr(AscB(MidB(Binary,i,1)))
ConvertBin = ConvertBin & strChar
Next
End Function
dim objStream
dim strTag, strSongName, strArtist, strAlbum, strYear, _
strComment, strGenre, strFile
'Specify the folder to iterate through, displaying all the MP3s
Const folder = "C:\mp3s\"
'Grab the folder information
Dim objFSO, objFolder, objFile
Set objFSO = Server.CreateObject("Scripting.FileSYstemObject")
Set objFolder = objFSO.GetFolder(folder)
'Create the Stream object
set objStream = Server.CreateObject("ADODB.Stream")
objStream.Type = adTypeBinary
'Loop through the files in the folder
For Each objFile in objFolder.Files
'Open the stream
objStream.Open
objStream.LoadFromFile objFile.Path
'Read the last 128 bytes
objStream.Position = objStream.size - 128
'Read the ID3 v1 tag info
strTag = ConvertBin(objStream.Read(3))
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
response.write "" & _
"ID3 Tag info for: |

"| " & objFile.Name & " |

response.write "| Artist: | " & _

objStream.Close

%>
自己试试吧
