用ASP實現對MP3曲目資訊的操作

先簡單說一下MP3的ID3 標記，因為主要是操作這個玩意

MP3最開始的時候沒有我們今天看到的那樣，有歌手、年代，專集等等資訊

只有一些簡單的參數如yes/no來表示是不是privated或者copyrighted等資訊，這樣對MP3的相關工作帶來了很多不便，1996年的時候有個老外提出來在每個MP3後面追加一段資料，用以存放上述的那些資訊，後來就發展成為id3 v1 據我所知的現在已經到1.1了，具體的還是自己去查一下吧

還是老習慣，用metadata來引入DLL，我以前有文章貼過的，不知道的請自己去查

看代碼

<!--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>Comment: </b>" & _

response.write "</table>"

objStream.Close

Response.Write "<p><hr><p>"

Next

Set objStream = Nothing 'Clean up...
