How can I record my voice without pause?

I made a voice control ping-pong game with matlab gui.

In the middle of the game, pressing "r" initiates recording for 1 sec.

Problem is, the game stops just for 1 sec if I press "r" which means, nothing happens during recording.

Since the title of my project is "real-time voice control ping-pong game", this problem should be solved.

Any ideas???

You need to use the facilities of the Audio System Toolbox. audiorecord() is not suitable for this purpose.

Yes, I used audiorecord()... Is there any ways to solve my problem without buying Audio system toolbox??

[Walter Roberson]

audiorecorder() has a record() method that is not blocking. However it cannot be used for continuous voice input, as the data is not available until the end of the recording period. You cannot just keep calling the record method repeatedly because of the setup time -- that is, you would get gaps in the input.

The DSP toolbox has a continuous audio input function.

sry, I have one more question. How can I stop record function? I mean, I want to record just for 1 second, but I have no idea how to do this...
