[Qt-interest] Waveform of audio tracks

[Vijay Kansal]

Hi,
I want to create an audio editor,
in which i have to create a widget that shows waveforms of audio tracks.
For this, i think i should use Qpainter to draw lines proportional to audio
amplitude.
Problems:How to get the ampliude of my audio track.
Secondly, on which widget shall i paste the waveform (lines produced by
Qpainter object  )
Is there any way of producing ths waveform (may be any built-in widget of
QT or so)?

Thanks.
