There is something broken in the way it generates the ramp.

I think this is what is happening:

I use qAbs(m_ramp -1) to get the amplitude and that wraps when m_ramp is 
-32767. This happens at the very end of the ramp up period and injects a 
single sample of zero amplitude into the full output sine wave. This is 
making the distortion.

I need to fix my ramp logic so that I don't have to subtract 1 from it.
