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 

<!--METADATA TYPE="typelib" 
UUID="00000205-0000-0010-8000-00AA006D2EA4" 
NAME="ADODB Type Library" 
--> 

<% 
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 "<table><tr><td colspan=2><h3>" & _ 
"ID3 Tag info for:</td></tr><tr>" & _ 
"<td colspan=2>" & objFile.Name & "</td></tr>" 
response.write "<tr><td><b>Artist: </b></td>" & _ 
"<td>" & strArtist & "</td></tr>" 
response.write "<tr><td><b>Track: </b></td>" & _ 
"<td>" & strSongName & "</td></tr>" 
response.write "<tr><td><b>Album: </b></td>" & _ 
<td>" & strAlbum & "</td></tr>" 
response.write "<tr><td><b>Year: </b></td>" & _ 
"<td>" & strYear & "</td></tr>" 
response.write "<tr><td><b>Comment: </b>" & _ 
"</td><td>" & strComment & "</td></tr>" 
response.write "</table>" 

objStream.Close 

Response.Write "<p><hr><p>" 
Next 

Set objStream = Nothing 'Clean up... 
%> 

自己试试吧 

希望能对你有所帮助
