Do not use wavrecord, since it is removed. If anyone has a newer version of MATLAB, he/she can not use your code. http://www.mathworks.com/help/matlab/ref/wavrecord.html

MATLAB: How to change wavrecord to audiorecorder

Poison - just replace your line of code

 x=wavrecord(Fs,Fs);

with the following

 % create the recorder
 recorder=audiorecorder(Fs,8,1);
 % record one second of data
 record(recorder,1);
 % get the samples
 x = getaudiodata(recorder);

And you should be able to continue as before. See audio recorder for details.

MATLAB: What is the difference between Sound & Soundsc? And How can i play an audio file asynchronously

Is there something from the description that you don't understand: " soundsc(y) scales the values of audio signal y to fit in the range from –1.0 to 1.0, and then sends the data to the speaker at the default sample rate of 8192 hertz. By first scaling the data, soundsc plays the audio as loudly as possible without clipping. The mean of the dynamic range of the data is set to zero."

So soundsc() scales the sound to the max dynamic range while sound() does not. A quiet sound will sound quiet with sound(), but will sound louder with soundsc(). In other words, sound plays y, while soundsc does something like this:

maxy = max(abs(y));
louder_y = y / maxy;
sound(louder_y);
