How to stop sound in MATLAB?

When playing a sound using e.g:

sound(x,fs);

I sometimes by accident play the wrong one. If x is of substantial length, I currently try to wait until the sound has completed. Any suggestions on how to "abort" the playback? I've already tried

sound(mute,fs); % Mute is a short vector containi开发者_JAVA技巧ng all zeroes

But that didn't work. I'm using Windows by the way.

UPDATE:

The following solution proposed by kigurai seems to do the trick:

sound(x,fs); % Start the audio

Now kill audio by

clear playsnd


Try this command Definitely works !!

clear sound


Mathworks says (and this applies to sound as well),

There is no function in MATLAB that can pause or stop audio playback once initiated by WAVPLAY. Instead of using WAVPLAY, an alternative is to create an AUDIOPLAYER object. This type of object has methods which allow pausing, resuming and stopping the audio playback. For example:

player = audioplayer(Y, Fs)

% start the playback
play(player);

% pause the playback
pause(player);

% resume the playback
resume(player)

% stop the playback
stop(player)


Never used "sound()" but when I have played audio using wavplay(..., ..., 'async') I can stop the sound by issuing

clear playsnd

Maybe that works with sound() as well? Note: This is when playing asynchronously. For synchronous playback I assume that CTRL-C should break it, but I had issues with wavplay() last time I tried that.


Use the audioplayer object instead - it gives you the full control on what you do with the sound. I.e:

player = audioplayer(x, fs);
play(player)   % start the player
stop(player)   % stop whenever you like...

Audioplayer has a lot of other useful stuff: http://www.mathworks.com/help/techdoc/ref/audioplayer.html
