用ASP实现对MP3曲目信息的操作(转)

原创 Linux操作系统 作者:jcszjswkzhou 时间:2019-04-07 10:24:06 0 删除 编辑
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
