  • You just plot the sample values against time - which part of this are you having difficulty with ? – Paul R Dec 18 '12 at 08:44
  • I have a problem with parsing song... I found ringdroid app which draw aplitude curve, but in some reason (I still dont know why...), loud song have less frame gains against to soundless song. – Jakub Apr 13 '13 at 10:06
