how to make a perceptual spectrum analyzer? the magnitude output of rfft~ seems to need some tweaking, like: 1) correcting amplitude of bins 2) spacing the bins from equally linearly spaced to equally logarithmic spaced (for outputting a set of frequencies like: 62 125 250 500 1000 2000 4000 8000 16000)
does anyone already did it? in part 2), apart I don't know how to do it, I'm not sure if I need to sum up all the bins belonging to a frequency band, or to average them ...? ~
