@flo-l

I'm not at all sure exactly what you are wanting to do or ask but yes, the pitch difference between 50Hz and 300Hz is about 2.5 octaves. Double the frequency is a change of one octave, so 50Hz x 2 = 100Hz (one octave), 100Hz x 2 = 200Hz (two octaves), 200Hz x 1.5 = 300Hz.

I am not sure what @flo-l is stating either, but the 'atypical' frequency range for the human voice is 100 to 10,000 Hz, Most engineers roll off frequencies above and below that.. there is not much sense for including frequencies that do not exist in dialog tracks. As an added benefit, it attenuates plosives, sibilance and extraneous noise in those frequencies as well for a cleaner sound track.

Thanks a lot to explain, the calcul is more clear now. It's to use band pass on voices in a speech. Maybe I need the analysis spectrum to be more precise for the range of frequencies I want to boost.

Off hand, I do not know if AS has a spectrum display tool like SFP. Voxengo's 'Span' a free VST plug-in, is a spectrum display tool and may useful. I do not recall it will freeze a selection though.
