I need to program a function that records an audio response, but when the voice of the person speaking reaches a certain intensity I need to know it on-line. Currently I am using this for recording:

PsychPortAudio('GetAudioData')

I can't analyze the intensity of the voice (using norm for example) on-line.

You should be able to do this with the analoginput command.

AI = analoginput('winsound');
addchannel(AI,1);

Then use:

x = getdata(AI, t);

To collect it. You'll need to set up some buffer length (say 1 second) and get the data, then perform whatever amplitude analysis you want.
