New Post: Can't make spectrum to work - VB 2010

Ok, the issue was solved but now I want to create the wave..

I read that I need to read until the end but didn't understand. I check the codes, even the WPF one, but still. I'm working with VB 2010 and maybe I can't understand exactly

mp3Reader = New Mp3FileReader(archivo)
waveChannel = New SampleChannel(mp3Reader, True)

Dim frame As Mp3Frame
Dim x As Integer = 1

While x < 50 ' just 50 for test
     frame = mp3Reader.ReadNextFrame()

     WaveformPainter1.AddMax( ???? )

      x = x + 1
End While
