WoLoSoft MP3Info Control

Dim analyzer
Set analyzer = WScript.CreateObject( "MP3Info.Control" )
analyzer.max_frames = 100
AnalyzeFolder( "P:\Sound\Files\MP3\Demo" )

Function AnalyzeFolder( folderspec )
  Dim fso, folder, file, filescollection
  Set fso = CreateObject("Scripting.FileSystemObject")
  Set folder = fso.GetFolder(folderspec)
  Set filescollection = folder.Files
  For Each file in filescollection
    AnalyzeFile( file.Path )
  Next
End Function

Function AnalyzeFile( filespec )
  WScript.Echo( filespec )

  analyzer.OpenFile( filespec )
  WScript.Echo( "Duration=" & analyzer.Duration )
  WScript.Echo( "Title=" & analyzer.Title )
  WScript.Echo( "Artist=" & analyzer.Artist )
  WScript.Echo
End Function

The MP3Info package contains 2 additional samples that demonstrate how to use the control with JScript and how to embed it in an HTML page.

Distribution

The control (mp3info.dll) may be used and distributed with your application as is. There are no license fees and distribution fees. The control uses the Xaudio Xanalyze SDK and the xanalyze.dll. In order to distribute the xanalyze.dll file you must sign a license agreement with Xaudio.

If you need the source code of the control (ATL project) you can order it from WoLoSoft for $199.00.

Installation

The MP3Info.dll is a self-registering control. You must install both files, MP3Info.dll and xanalyze.dll to the same directory. It is important that you install the xaudio.dll file before you register the MP3Info control.
