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"

  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>" & _

    response.write "<tr><td><b>Track: </b></td>" & _

    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
