Resources | VB | Encoding Variable Bit Rate WMAs

Encoding Variable Bit Rate WMAs:

The following code requires the download of the Windows Media Encoder SDK.

As I've mentioned before, the Windows Media Encoder makes life a lot easier for VB developers working with audio files. However, the documentation for the SDK can be a bit sparse in certain areas.

One thing that is not mentioned in the documentation is that Visual Basic cannot handle encoding WMA files with a Variable Bit Rate (VBR) profile. VB has no problem encoding WMAs with Constant Bit Rates, but not VBRs. So if you need to encode VBRs in Visual Basic, you need to make a command line call to a .VBS (wmcmd.vbs) file that comes with the SDK.

For this tutorial, we will use the following VBR PRX (encoder Profile). Copy the text and save it in the folder with your VB Application, naming it VBRProfile.prx:

Now add a module to your VB project, which will handle the calls to the command line:

Private Type STARTUPINFO cb As Long lpReserved As String lpDesktop As String lpTitle As String dwX As Long dwY As Long dwXSize As Long dwYSize As Long dwXCountChars As Long dwYCountChars As Long dwFillAttribute As Long dwFlags As Long wShowWindow As Integer cbReserved2 As Integer lpReserved2 As Long hStdInput As Long hStdOutput As Long hStdError As Long End Type Private Type PROCESS_INFORMATION hProcess As Long hThread As Long dwProcessId As Long dwThreadId As Long End Type Declare Function CreateProcessA Lib "kernel32" _ (ByVal lpApplicationName As Long, ByVal lpCommandLine As _ String, ByVal lpProcessAttributes As Long, ByVal _ lpThreadAttributes As Long, ByVal bInheritHandles As Long, _ ByVal dwCreationFlags As Long, ByVal lpEnvironment As Long, _ ByVal lpCurrentDirectory As Long, lpStartupInfo As _ STARTUPINFO, lpProcessInformation As PROCESS_INFORMATION) _ As Long Private Declare Function WaitForSingleObject Lib _ "kernel32" (ByVal hHandle As Long, ByVal dwMilliseconds _ As Long) As Long Declare Function CloseHandle Lib "kernel32" (ByVal hObject _ As Long) As Long Private Const NORMAL_PRIORITY_CLASS = &H20& Private Const INFINITE = -1& Public Sub ExecCmd(cmdline$) On Error GoTo execErr Dim proc As PROCESS_INFORMATION Dim start As STARTUPINFO 'Shell (App.Path & "\" & cmdline) 'Initialize the STARTUPINFO structure: start.cb = Len(start) 'Start the shelled application: Ret& = CreateProcessA(0&, App.Path & "\" & cmdline$, 0&, 0&, 1&, _ NORMAL_PRIORITY_CLASS, 0&, 0&, start, proc) 'Wait for the shelled application to finish: Ret& = WaitForSingleObject(proc.hProcess, INFINITE) Ret& = CloseHandle(proc.hProcess) Exit Sub execErr: Err.Clear Exit Sub End Sub

Then add this code to your VB form to encode your audio file to a VBR WMA. The encoding object can accept either an MP3 or WAV file. Make sure you include a fully qualified path to your audio file.

Sub EncodeVBR() CScriptPath = "cscript.exe " & App.Path & "\wmcmd.vbs -input " & inputPathAndFileName & _ " -output " & outputPathAndFileName & _ " -author "" " & Author & " "" " & _ " -description "" " & Description & " "" " & _ " -copyright "" " & Copyright & " "" " & _ " -title "" " & Title & " "" " & _ " -loadprofile " & App.Path & "\VBRProfile.prx" End If 'this is a call to the function in your Module StartAppAndWait CScriptPath, vbNormalFocus End Sub

Make sure you have placed the wmcmd.vbs file in the same folder as your VB application. Here is the code for the vbs script (it comes with the SDK so you should already have it):
