how to make a perceptual spectrum analyzer?
the magnitude output of rfft~ seems to need some tweaking, like:
- correcting amplitude of bins
- 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 ...?
