Ok, new problem

[polmc]

Ok, thanks for all your help!

I have a new problem though:

When I try to write the wav (with wavwrite), 2 things can happen:

1. It writes, but when I try playing the sound, it says that the format is
damaged or that it doesn't have propper codec.

or

2.Octave sends an error saying that it has too many colums...

This is my script: 


function sinte(f)
  
Fs = 44100;

t = 0:1/Fs:2;

  
  tau1 = 0.044;
  A1 = 28184;
  f1 = f;
  x1 = A1*exp(-t/tau1).*sin(2*pi*f1*t/Fs);
  
    tau2 = 0.036;
  A2 = 7943.3;
  f2 = f*2;
  x2 = A2*exp(-t/tau2).*sin(2*pi*f2*t/Fs);
  
    tau3    = 0.048;
  A3 = 2818.4;
  f3 = f*6;
  x3 = A3*exp(-t/tau3).*sin(2*pi*f3*t/Fs);
  
    tau4 = 0.015;
  A4 = 7943.3;
  f4 = f*4;
  x4 = A4*exp(-t/tau4).*sin(2*pi*f4*t/Fs);
  
    tau5 = 0.021;
  A5 = 1778.3;
  f5 = f*5;
  x5 = A5*exp(-t/tau5).*sin(2*pi*f5*t/Fs);

  tau6 = 0.018;
  A6 = 2818.4;
  f6 = f*6;
  x6 = A6*exp(-t/tau6).*sin(2*pi*f6*t/Fs);
  
  
  tau7 = 0.016;
  A7 = 1258.9;
  f7 = f*7;
  x7 = A7*exp(-t/tau7).*sin(2*pi*f7*t/Fs);
  
  tau8 = 0.017;
  A8 = 794.3;
  f8 = f*8;
  x8 = A8*exp(-t/tau8).*sin(2*pi*f8*t/Fs);
  
  tau9 = 0.038;
  A9 = 100.0;
  f9 = f*9;
  x9 = A9*exp(-t/tau9).*sin(2*pi*f9*t/Fs);
  
  tau10 = 0.017;
  A10 = 562.3;
  f10 = f*10;
  x10 = A10*exp(-t/tau10).*sin(2*pi*f10*t/Fs);
  
  x = x1+ x2 + x3 + x4 + x5 + x6 + x7 + x8 + x9 + x10;

  wavwrite(x,Fs,16,"senyal.wav")
  
  endfunction

What can I do?
