generationsound wave

how can i generate a sound wave through matlab?

Best Answer

Fs = 4.41E+4;
t = linspace(0, Fs*5, Fs*5);
f1 = 1E+3;
f2 = 1E+1;
s = sin(2*pi*f1*t/Fs) .* cos(2*pi*f2*t/(5*Fs));
sound(s, Fs)

Experiment to get the result you want.

MATLAB: Not enough input arguments

Is this what you mean?

    y = 2*cos(2*pi*((f1+f2)/2)*t)*cos(2*pi*((f1-f2)/2)*t);

MATLAB: Plot the STFT spectrogram

The function tutorials of matlab normally give code examples and results. For you to reproduce the result you just need to run the exactly same given code. In this case, just copy the code lines before and you will get the same picture:

fs = 10e3;
t = 0:1/fs:2;
x = vco(sin(2*pi*t),[0.1 0.4]*fs,fs);
stft(x,fs,'Window',kaiser(256,5),'OverlapLength',220,'FFTLength',512);
