analyze

frequency plot of a sound signal

Arguments

fmin,fmax,rate,points

scalars. default values fmin=100,fmax=1500,rate=22050,points=8192;

Description

Make a frequency plot of the signal w with sampling rate rate. The data must be at least points long. The maximal frequency plotted will be fmax, the minimal fmin.

Examples

// 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));
analyze(s);
