This article started with an question from John Nell [http://bose.infopop.cc/eve/forums/a/tpc/f/7521050644/m/5011087105?r=5011087105#5011087105 T1 Newbie Questions/Solutions] | |||
:I understand the concept of notch filters. I'm thinking the ParaEQ works in a similar way, and I understand Level and Freq options. I'm having trouble understanding the Width function. I understand the bell curve concept around a center frequency, but can someone diagram for me the .20 to 5.00 octave width? Exactly, what does this look like on the bell curve? What do the values, .20 and 5.00 mean visually? A diagram to explain it would be great, but I don't understand the "octave" part of it. | |||

The following are extremely rough approximations. For anyone reading - there is nothing scientific about these plots. The appearance suggests a level of precision that is way beyond what I did to create these images. (Normal distribution curve, manipulated the standard deviation). Just go for the rough visual impression. Thanks! | The following are extremely rough approximations. For anyone reading - there is nothing scientific about these plots.
