[mehboob_iiui]

Can I record audio in matlab , plugging my microphone into the line in of my sound card,
actually I want to record from two microphones, simultaneously,

how can it be possible?

Hi
You can use Matlab's Data aquisition toolbox.

this toolbox provides you the necessary functions for capturing audio signals from your soundcard.

This code acquires and plots 5000 samples of two-channel audio at sample rate 22050.
It works in Windows. I don't think it requires any toolbox.
You may need to configure your sound card and/or mixer for two-microphone input.

y = wavrecord(5000, 22050, 2);
subplot(2,1,1); plot(y,1));
subplot(2,1,2); plot(y,2));
