I'm trying to learn, for the first time, to work on matlab (which I'm starting to find an amazing tool), because I need to analyze the two microphone signals of an Impedance Tube that I've built.

Now, I have the ISO standard and I'm trying to start implementing the transfer function between the two audio signals, but I really don't know how to do it.

Shall I pass am fft analysis to the signals and then "tf"? When I do this the PC frezz. As a complex signal, shall I "tf" the complex and real part separatly, or something else?

I'm really confused with this.. (Worried)

I someone can help me in this endeavor(Wink) , I would be greatly apreciated.
