New Post: Stuck in no mans land -> but yet so close :-/

In a mix of trying to alter code fom this tutorial:  https://www.youtube.com/watch?v=ZnFoVuOVrUQ

 - and trying to get the peak values of a recorded wave I ended up with this:

while (wave.Position < wave.Length )
            {
                read = wave.Read(buffer, 0, 16384);

                for (int i = 0; i < read / 4; i++)
                {                  
                            if (i < 5000){   
                            chart1.Series["wave"].Points.Add(BitConverter.ToSingle(buffer, i * 4));

                            liste.Add(chart1.Series["wave"].Points[Convert.ToInt32(wave.Position/4096)].YValues[0]);
                                         }

                            if (wave.Position % 16384 == 0 && i % 4096 == 0)
                            {
                                Console.WriteLine("Values!!: "+ liste[i]);
                                Console.WriteLine("values: " + chart1.Series["wave"].Points[Convert.ToInt32(BitConverter.ToDouble(buffer, i / 4))].YValues[0]);
                            }                      
                }
                textBox1.Text = Convert.ToString(optaelPeaks);
                textBox2.Text = Convert.ToString(wp);
            }

-  but the output of this code doesn't really makes sense in the console as all the values lays between 0.027 and 0.089 (in a very looping-like pattern, that doesn't resembles the .wav I am analyzing/loading), as opposed to the chart1 that shows values from -1.0 to 1.0.

I have also been checking up on Voicerecorder and this link: http://stackoverflow.com/questions/14350790/naudio-peak-volume-meter

- without getting further (as a Dane I have trouble with more in depth math English terms like: "take the log base 10 of the maximum value") ... Hope you can help me /on before hand thx /Thomas
