How to convert wav to mp3 using VB?

Expand Post »
Dear gurus and members,
I am a newbie in VB and programming. I have created an exe that allows to record, play and save user's speech onto his computer. The file is saved as wav. I wonder is it possible to convert the files to mp3 format when user clicks on Save button? I use VB6 to create the MCI and currently stucked in the convertion of wav to mp3. The following is the code of my Save button

Visual Basic 4 / 5 / 6 Syntax (Toggle Plain Text)
  1. Private Sub cmdSave_Click(ByVal eventSender As System.Object, ByVal eventArgs As System.EventArgs) Handles cmdSave.Click
  2.  
  3.         Dim sName As String
  4.         counter = counter + 1
  5.         sName = "Test" & counter
  6.  
  7.         WaveSaveAs((VB6.GetPath & "\" & sName & ".wav"))
  8.         cmdRecord.Enabled = True
  9.         cmdStop.Enabled = True
  10.         cmdPlay.Enabled = True
  11.         cmdSave.Enabled = False
  12.         cmdReset.Enabled = False
  13.         Exit Sub
  14.  
  15. End Sub

I would be very glad if someone could share the knowledge and expertise in this area with me. Looking forward to some replies soon.

Thanks in advance,
Janice

Re: How to convert wav to mp3 using VB?

The short answer is "You can't". It *is* possible, but the MP3 format is proprietary, so if you created an MP3 you could be facing a lawsuit. There are plugins and libraries that offer MP3 export functions, but you'll probably pay quite a bit for them, since they also had to pay for a license to use the MP3 format.

I can't help you with this either, but you might consider OGG (Ogg Vorbis) format. It's a smaller file, and slightly better quality than MP3. Plus it's OGL, so it's free.
