Hi everyone,

I’m in the process of learning Octave and one of my tasks is to output an audio signal. Before that I wrote a function and this should then emit a sound. But when I use the sound function, I get the following error message:

error: audioplayer: NBITS must be 8, 16, or 24

error: called from

audioplayer at line 112 column 19

sound at line 64 column 8

this is the function in the edit window:

```
function x = MySinus(Nsamp);
Fs = 8000;
Ts=1/Fs;
t = [0:Ts:Ts*(Nsamp-1)];
n = [1:Nsamp];
f1 = 500; f2 = 1250; f3 = 2000;
x1 = 0.5 * sin(2*pi*f1*t);
x2 = 0.25 * sin(2*pi*f2*t);
x3 = 0.25 * sin(2*pi*f3*t);
x = x1 + x2 + x3;
plot(t,x);
end;
```

Command window:

```
y = MySinus(8000);
sound(y);
```

Maybe someone has an example that works on a Mac.
