mapsound

Plots a sound map

Calling Sequence

mapsound (w,dt,fmin,fmax,simpl,rate)

Arguments

:dt,fmin,fmax,simpl,rate scalars. default values

dt=0.1,fmin=100,fmax=1500,simpl=1,rate=22050;

:

Description

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.

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));
mapsound(s);
