FirstFreqIndex
index of the first filter; the exact centre filter frequency in Hertz
according to its index is given by the following formula:
f = 1000 · G
i/b
– for odd value b
f = 1000 · G
(2i+1)/(2b)
– for even value b
where:
G = 2 – for filter base 2
G = 10
0.3
– for filter base 10
i – filter index
b – octave division
