I need to represent time-frequency diagram using
a personalized frequency scale and not the one by defalut.
How I could do?
you can do :
s=fmlin(128);
[tfr, t, f]=tfrsp(s);
pcolor(t,f(1:64).^2,tfr(1:64,:));
shading("flat");
which produces a spectrogram with the frequency remapped
to frequency squared.
