I want to record, analysis and plot the audio signal simultaneously from sound card.

I execute demoai_fft.m program and try to store the plotted signal. But the store result only have partially audio signal not all signal.

How do I accomplish this feature?

When using wavrecord/record functions, could I get some audio frame to analysis and plot while recording?

Thanks, Adrian.
