MATLAB: What function to display the result of wavread

audio

[x,fs] = wavread('E:\Example\tes.wav');

if i use plot(x); there will be a graph of sine wave.

But the display i wanted is in array of the data/sample data or something?

Anyone know what function should i use?

Do you mean like

x(1:100,1)

to display the numeric values of the first 100 samples?

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);
