So, what resolution of the drawed curve do you want?<br>
If you want to parametrize freq. resp. curve with small set of numbers, it's just conventional equalizer that lets you do so.<br>
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).<br>
Resynthesis just adds an fft.<br>
AFAIC.<br>
