is it possible to perform real time processing on matlab..i mean can processing on speech signal be done while i am recording my speech signal?

I want to perform real time operation on speech signal...i want to apply fft on my speech signal but in real time...suppose i want to record speech for 10 sec..and i have completed recording for 2 sec...so while i am recording the remaining part of my speech signal can i get the fft of the signal that is been recorded for 2 sec? if yes, please guide me...thanks

post your code of reoording

This can be done in a couple different ways depending on your application.

If you want to be able to actively perform this process while recording you may want to utilize Simulink with data acquisition

If you are simply interested in the results you can record the signal and then feed it into the FFT function in MATLAB.

thanks...i will try simulink with data acquisition
