Analyze audio using Fast Fourier Transform
...e above 25hz).
Depending on how many bars you want, you divide the whole range into 1/X octave ranges.
Based on a given center frequency of A on the bar, you get the upper and lower limits of the bar from:
upper limit = A * 2 ^ ( 1 / 2X )
lower limit = A / 2 ^ ( 1 / 2X )
To calculate the next a...
