So if you were to play a tone, say at 440Hz there should appear a spike at 440 along the x-axis in the graph. So it does give you some interesting insights into the audio waveform. Adding FFTW to the Qt Project. If the FFTW3 libraries are installed then all that is needed should be to add the following line to your Qt project .pro file.

The audiolevels example shows how feed real-time dynamic data to a graph using Q3DBars. This example reads the audio levels from a microphone and displays those levels in a bar graph. To increase the load for demonstration purposes, and to make the graph little fancier, slightly modified data is used to fill multiple rows.
