Probably a stupid question

Probably a stupid question

But here goes anyway:

So when I'm looking at my mix with a RTA plug-in on the 2-bus, I notice that the top end of the graph rolls off at 20K but still goes off the graph albeit at around -80dB or so while commercial mixes seem to drop off the chart completely right at about 20kH with absolutely no carry-over beyond.

Even if I low pass everything at 20k or even 18k, I still see it bleed out off the chart.

I'm assuming this is something that's done in mastering but I'm curious as to how or if I'm missing something.

Thanks

You may be seeing a characteristic of your low pass filter. It depends on how much roll off per octave your filtering is set at as to how steep of a cutoff you will see on either hi pass or low pass filtering. Some filters are have set slopes around (just throwing this out there) 18dB per octave or something around that and selectable to a steeper slope (the higher the dB per octave, the more severe the cutoff is). Mastering engineers have a plethora of options at their disposal for filtering purposes. Just my thoughts.
