Dispersion curves and wavenumbers

Hola,

I have vibration signal measured on rotating machinery consiting of 1D values (length 13000), measured by 2 sensors at different edns of the machines which get stored as wave files. I would like to compare both sensor signals in the following ways, however I am stuck on a few things.

I would like to analyse the dispersion differences between sensor 1 and sensor 2. To do this, I believe I need to plot dispersion curves for both sensors? Does anyone know how to get dispersion curves for signals, based on .wav input?

I believe wavenumber K=2pi/lambda.

I would also like to analyse frequency velocity, I beleive this can be done by taking freq/wavenumber. Please direct me if this is incorrect.

Gracias,

Ben
