So, what resolution of the drawed curve do you want?
If you want to parametrize freq. resp. curve with small set of numbers, it's
just conventional equalizer that lets you do so.
When you want a curve with arbitrary many points that represents A(F) as
precisely as possible, then you can't avoid rfft of the curve (to convolute
with the audio stream; the convolution in integral form in itself requires
element-by-element vector multiplication).
Resynthesis just adds an fft.
AFAIC.
