wavread and wavplay

Hi,

I have 2 sound files in .wav format. I need to run those two files.
When i am playing first sound file, if i want to stop it and want to play the second, what do i do??

Just have look at the following:
[y, Fs] = wavread('F:\sound_1.wav');
[y1, Fs1] = wavread('F:\sound_2.wav');
wavplay(y,Fs,'async') ;
wavplay(y1,Fs1,'async') ;

Here, 1st sound file which is running has to be stopped as soon i execute the 4th line code.

Any help would be greatly appreciated ..

The problem is that you put a whole block of data into y and y1.
Lets say it is a 2min Track then it need 2min till it will finished. To solve this problem, you have to write an m-file wich puts only small blocks into y and y1 and everytime time the data is done, refill/put again the y or y1.

Hope that helps a bit.

try slipping in a 'clear playsnd' statement before you want to play the second sound.
