need help on impedance tube signal analysis

Feb 2010
Hello to all,

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.
