Hi everyone

My problem is about estimation of TDOA by the function Pseudo spectrum MUSIC.

I have 2 real signals that I recorded with two separated microphones. My signal is in fact a sinus 500 Hz. I try to plot the spectral estimation with this function but the result is not clear for me: The x axis is in rad/sample??? I want to show this in degree. What can I do???

Thanks.
