Hi,

during my experimenting I connected the qt freq display just directly to
an audio source. sample_rate is set to 44.1k, center freq to 22.05k.

I absolutely did not see what I expected to see, so I connected the
display to a signal source, sending a 1k sinus tone.

Instead of seeing one spike pretty much left on the display, I saw a
spike in the center.
Next I took a 2nd signal source at 5k, put both sources through an add
operator into the display and instead of 2 spikes, there still was only
one spike in the center.

What do I miss here?
