I have loaded the spectrum-meter in my master track and the Pro EQ² in my bass-drum track. When I solo this bass-drum track, I expect both to display the same frequencies, since the same sound is playing through. Nevertheless, you can see on the screen-shoot that the spectrum-meter shows a peak at around 70 Hz, while the Pro EQ² shows this peak at around 30 Hz. Why are these two curves different and which of the two is the valid one?
