Plots a sound map
mapsound (w,dt,fmin,fmax,simpl,rate)
scalars. default values dt=0.1,fmin=100,fmax=1500,simpl=1,rate=22050;
Plots a sound map for a sound. It does FFT at time increments dt.
rate
is the sampling rate. simpl
points are collected for
speed reasons. fmin
and fmax
are used for graphic
boundaries.
// At first we create 0.5 seconds of sound parameters. t=soundsec(0.5); // Then we generate the sound. s=sin(440*t)+sin(220*t)/2+sin(880*t)/2; [nr,nc]=size(t); s(nc/2:nc)=sin(330*t(nc/2:nc)); mapsound(s); | ![]() | ![]() |
