Hi,
I want to draw the 2D diagram of digital wave forms. Am new to Qt. Am having Qt 4.4 with Visual Studio 2008. How could i start with? for 0 the waveform should be lower and for 1 the waveform should be higher. I need to set up zoom, pan e.t.c.,

Have a look at the Qwt library (http://qwt.sourceforge.net/).
Will save you some work.
(Of course, if you want to learn Qt... have a look at the tutorials and implement your own waveform widget. Appreciate the learned things and then still use Qwt.)

Hi,
But suggest some other links other than QWT.

In this case QWT is not the better option. I did a small audio editor where, after decoded, I drawn the audio samples
over a widget inherited from QWidget.
Hi, which tool are you using to decode the audio files? ffmpeg?
