 Now, we extract brut data (PCM, Pulse Code Modulation, each points is between 1 and -1) to detect peaks.

 To do this job, we start with a thresold setted to 0.9 (on the amplitude axis) and we search a minimal peak number (~15) by decrementing this thresold by 0.05 through all the AudioBuffer.
 When we find a peak, we jump 10000 peaks index (1/4 second) to ignore the descendant phase of the peak...
