converting a frequency to audible tone?

hey can you help me...i got a frequency by applying fft to a signal and selecting max peak of it..can i convert that frequency to an audible tone? While i was searching through, i got a code like this but it is not working .

Fs = 1000;  
nSeconds = 5;  

frequency = 100;  
y1 = 100*sin(linspace(0, nSeconds*frequency*2*pi, round(nSeconds*Fs)));  
aud1 = audioplayer(y1, Fs);  

frequency = 200;  
y2 = 100*sin(linspace(0, nSeconds*frequency*2*pi, round(nSeconds*Fs)));  
aud2 = audioplayer(y2, Fs);  

% overlapping sound impossible  
sound(y1, Fs);  
pause(1)  
sound(y2, Fs);  

% overlapping sound possible  
play(aud1);  
pause(1);  
disp('can compute here');
play(aud2);  

pause(1);  
stop(aud1);  
pause(1);  
stop(aud2);  
end

.plz reply

Here's my demo code on how to make a sound.

I don’t know what you mean by ‘is not working’. You can play one sound at a time or both simultaneously in stereo. I found that using the sound function worked well, and audioplayer and play did also.

Creating and playing a stereo sound with your vectors:

y12 = [y1; y2]';                % Create Stereo

sound(y12,Fs)

If you want to hear the full effect, introduce a time offset in both signals. This will start by playing the right channel, then both channels, then the left channel:

y12 = [zeros(1,1000) y1; y2 zeros(1,1000)]';
sound(y12,Fs)
